FOREWORD 

Section 304 (a)(1) of the Clean Water Act of 1977 (P.L. 95-217), 

requires the Administrator of the Environmental Protection Agency to 

publish criteria for water quality accurately reflecting the latest 

scientific knowledge on the kind and extent of all identifiable effects 

on health and welfare which may be expected from the presence of 

pollutants in any body of water, including ground water. Proposed water 

quality criteria for the 65 toxic pollutants listed under section 307 

(a)(1) of the Clean Water Act were developed and a notice of their 

availability was published for public comment on March 15, 1979 (44 FR 

15926), July 25, 1979 (44 FR 43660), and October 1, 1979 (44 FR 56628). 

This document is a revision of those proposed criteria based upon a 

consideration of comments received from other Federal Agencies, State 

agencies, special interest groups, and individual scientists. The 

criteria contained in this document replace any previously published EPA 

criteria for the 65 pollutants. This criterion document is also 

published in satisfaction of paragraph 11 of the Settlement Agreement 

in Natural Resources Defense Council, et. al. vs. Train, 8 ERC 2120 

(D.D.C. 1976), modified, 12 ERC 1833 (D.D.C. 1979). 

The term "water quality criteria" is used in two sections of the 

Clean Water Act, section 304 (a)(1) and section 303 (c)(2). The term has 

a different program impact in each section. In section 304, the term 

represents a non-regulatory, scientific assessment of ecological effects. The criteria presented in this publication are such scientific 

assessments. Such water quality criteria associated with specific 

stream uses when adopted as State water quality standards under section 

303 become enforceable maximum acceptable levels of a pollutant in 

ambient waters. The water quality criteria adopted in the State water 

quality standards could have the same numerical limits as the criteria 

developed under section 304. However, in many situations States may want 

to adjust water quality criteria developed under section 304 to reflect 

local environmental conditions and human exposure patterns before 

incorporation into water quality standards. It is not until their 

adoption as part of the State water quality standards that the criteria 

become regulatory. 

Guide lines to assist the States in the modification of criteria 

presented in this document, in the development of water quality 

standards and in other water-related programs of this Agency, are being 

developed by EPA.

COPPER 

CRITERIA 

Aquatic Life 

For total recoverable cooper the criterion to protect freshwater aquatic 

life as derived using the Guidelines is 5.4 μg/l as a 24-hour average and 

the concentration (in μg/l) should not exceed the numerical value given by 

e(0.94[ln(hardness)]-1.23) at any time. For example, at hardnesses of 50, 

100, and 200 mg/l as CaCO3 the concentration of total recoverable copper 

should not exceed 12, 22, and 43 μg/l at any time. 

For total recoverable copper the criterion to protect saltwater aquatic 

life as derived using the Guidelines is 4.0 μg/l as a 24-hour average and 

the concentration should not exceed 23 μg/l at any time. 

Human Health 

Sufficient data are not available for copper to derive a level which 

would protect against the potential toxicity of this compound. 

Using available organoleptic data, for controlling undesirable taste and 

odor quality of ambient water, the estimated level is 1 mg/l. It should be 

recognized that organoleptic data as a basis for establishing a water quality criteria have limitations and have no demonstrated relationship to potential adverse human health effects. 

vi 
Copper is a soft heavy metal, atomic number 29, with an atomic weight of 

63.54, a melting point of 1,083°C, a boiling point of 2,595°C, and a density 

in elemental form at 20°C of 8.9 g/cc (Stecher, 1968). Elemental copper is 

readily attacked by organic and mineral acids that contain an oxidizing 

agent and is slowly soluble in dilute ammonia. The halogens attack copper 

slowly at room temperature to yield the corresponding copper halide. Oxides 

and sulfides are also reactive with copper. 

Copper has two oxidation states: Cu I (cuprous) and Cu II (cupric). Cuprous copper is unstable in aerated water over the pH range of most natural 

waters (6 to 8) and will oxidize to the cupric state (Garrels and Christ, 

1965). Bivalent copper chloride, nitrate, and sulfate are highly soluble in 

water, whereas basic copper carbonate, cupric hydroxide, oxide, and sulfide 

will precipitate out of solution or form colloidal suspensions in the presence of excess cupric ion. Cupric ions are also adsorbed by clays, sediments, and organic particulates and form complexes with several inorganic 

and organic compounds (Riemer and Toth, 1969; Stiff, 1971). Due to the complex interactions of copper with numerous other chemical species normally 

found in natural waters, the amounts of the various copper compounds and 

complexes that actually exist in solution will depend on the pH, temperature, alkalinity, and the concentrations of bicarbonate, sulfide, and organic ligands. Based on equilibrium constants, Stumm and Morgan (1970) calculated copper solubility in a carbonate-bearing water. They found that cupric ion (Cu2+) would be the dominant copper species up to pH 6, and from 

pH 6 to 9.3 the aqueous copper carbonate complex (CuCO3 aq) would dominate. The presence of organic ligands such as humic acids, fulvic acids, 

amino acids, cyanide, certain polypeptides, and detergents would alter this 

equilibrium (Stiff, 1971). 

A-1 
Zirino and Yamamoto (1972) developed a model to predict the distribution 

of copper species in seawater. Mixed ligand complexes and organic chelates 

were not considered in the model. They predicted that the distribution of 

copper species in seawater would vary significantly with pH and that 

Cu(OH)2, CuCO3, and Cu2+ would be the dominant species over the entire 

ambient pH range. The levels of CU(OH)2 increase from about 18 percent of 

the total copper at pH 7 to 90 percent at pH 8.6. CuC03 drops from about 

30 percent at pH 7 to less than 0.1 percent at pH 8.6. Field and laboratory 

studies by Thomas and Grill (1977) indicate that copper adsorbed to sediments and particulates in freshwater may be released as soluble copper when 

it comes in contact with seawater in estuarine environments. 

Copper is ubiquitous in the rocks and minerals of the earth's crust. In 

nature, copper occurs usually as sulfides and oxides and occasionally as metallic copper. Weathering and solution of these natural copper minerals results in background levels of copper in natural surface waters at concentrations generally well below 20 μg/l. Higher concentrations of copper are usually from anthropogenic sources. These sources include corrosion of brass 

and copper pipe by acidic waters, industrial effluents and fallout, sewage 

treatment plant effluents, and the use of copper compounds as aquatic algicides. Potential industrial copper pollution sources number in the tens of 

thousands in the United States. However, the major industrial sources include the smelting and refining industries, copper wire mills, coal burning 

industries, and iron and steel producing industries. Copper may enter natural waters either directly from these sources or by atmospheric fallout of 

air pollutants produced by these industries. Precipitation of atmospheric 

fallout may be a significant source of copper to the aquatic environment in 

industrial and mining areas. 

A-2 
The levels of copper able to remain in solution are airectly depenaent 

on water chemistry. Generally, ionic copper is more soluble in low pH, 

acidfc wdters and less soluble in high pH, alkaline raters.

Aquatic Life Toxicology* 

INTRODUCTION 

concentrations of copper. Chronic data are available for only one species, 

Acute toxicity tests on cooper have been conducted with 45 freshwater 

species and chronic tests with 15 species. Although the acute toxicity of 

copper seems to be related to water hardness, chronic toxicity apparently is 

not. Freshwater plants show a wide range of sensitivities to copper, but 

few data are available concerning bioconcentration by freshwater organisms. 

Four fish and eighteen saltwater invertebrate species have been acutely 

exposed to copper. Results of these tests indicate a range of acute sensitivities from 28 μg/l for the summer flounder to 600 μg/l for the shore 

crab. Most of these tests were conducted using static procedures; however, 

seven species were exposed in flow-through tests with measurements of the 

but bioconcentration tests have been conducted with a wide variety of 

species. 

ion in free and complex forms, is a minor nutrient for both plants and aniCopper, which occurs in natural waters primarily as the divalent cupric 

mals at low concentrations but is toxic to aquatic life at concentrations 

not too much higher. Concentrations of 1 to 10 μg/l are usually reported 

for unpolluted surface waters in the United States, but concentrations in 

the vicinity of municipal and industrial outfalls, particularly from smelting, refining, or metal plating industries, may be much higher. 

*The reader is referred to the Guidelines for Deriving Water Quality Criteria for the Protection of Aquatic Life and Its Uses in order to better understand the following discussion and recommendation. The following tables 

contain the appropriate data that were found in the literature, and at the 

bottom of each table are calculations for deriving various measures of toxicity as described in the Guidelines. 

B-1 
The cupric ion is highly reactive and forms moderate to strong complexes 

and precipitates with many inorganic and organic constituents of natural 

waters, e.g., carbonate, phosphate, amino acids and humates, and is readily 

absorbed on surfaces of suspended solids. The proportion of copper present 

as the free cupric ion is generally low and may be less than 1 percent in 

eutrophic waters where complexation predominates. Various copper complexes 

and precipitates appear to be largely nontoxic and tend to mask and remove 

toxicity attributable to copper (Andrew, 1976). This fact greatly complicates the interpretation and application of available toxicity data, because 

the proportion of free cupric ion present is highly variable and is difficult to measure except under special laboratory conditions. Few toxicity 

data have been reported using measurements other than total or dissolved 

copper. 

Of the analytical measurements currently available, a water quality criterion for copper is probably best stated in terms of total recoverable 

copper, because of the variety of forms that can exist in natural waters and 

the various chemical and toxicological properties of these forms. The commonly occurring forms not measured by the total recoverable procedure, e.g., 

copper occluded in suspended mineral particulates, are farms that are less 

available to aquatic life and probably will not be converted to the more 

toxic forms readily under various natural conditions. The procedure for total recoverable copper, however, does measure those forms directly toxic to 

aquatic life, e.g., the free ion, and those labile forms (hydroxide, carbonate, and some phosphate precipitates) readily converted to more toxic forms 

under various natural conditions. Since the criteria are derived on the 

B-2 
3asis 3L tests conducted lising solubye inorganic c3Doer ja:tS, tots; Jo,: 

total recoverable cooper concentrations in the tests should be nearly equivalent, and the results are used interchangeably. 

Because a majority of the reported test results (Tables 1 and 2j nave 

been conducted with oligotrophic raters having relatively low complexing 

capacities, the criteria derived herein may be at or below ambient total 

copper concentrations in some surface waters of the United States. Season - 

ally and locally, toxicity in these waters may be mitigated by the presence 

of naturally occurring chelating, complexing, and precipitating agents. In 

addition, removal from the water column may be rapid due to normal growth of 

the more resistant aquatic organisms and settling of solids. The various 

forms of copper are in dynamic equilibrium and any change in chemical conditions, e.g., pH, could rapidly alter the proportion of the various forms 

present and, therefore, toxicity. 

Since increasing calcium hardness and associated carbonate alkalinity 

are both known to reduce the acute toxicity of copper, expression of the 

upper limit as a function of water hardness allows adjustment for these 

water quality effects, This results in a much better fit with the available 

acute toxicity data, because the upper limit is higher at high hardness to 

reflect calcium antagonism and carbonate complexation. Some data on the relationship of toxicfty to other factors, i.e., temperature, alkalinity, size 

of organism, and total organic carbon, are available for a limited number of 

soecies and wfll be dfscussed later. 

The follouing data on the effects of copper on aquatic biota (Tables I 

through 6) have been summarized front the literature from 1950 to 1980. Effqrts to.obtain residue data, or effects data on algae and other plants, 

were not exhaustive, since previous reviews have indicated. that these 

S-3 
effects are of nrinor impot:ance relative to toxicity of copper to fish and 

jnvertebrate species. 

11: concentrations are reoorted as cooper, not as the compound. 

EFFECTS 

&cute Toxicity 

Acute toxicity tests with czpper have been conducted on 18 invertebrate 

and 27 fish species (Table l), with approximately 175 acute values available 

for comparison. Most of these tests have been conducted with four salmonid 

species, fathead and bluntnose minnows, and bluegills. The acute values 

range from a low of 7.24 ug/l for Oaphnia pulicaria in soft water to 10,200 

;rg/l for bluegills tested in hard water. The majority of tests conducted 

since about 1970 have been flow-through tests with measurements of both 

total and dissolved copper. For comparative purposes, only values expected 

to be equivalent to total recoverable copper were included in the tables. 

?esults of Cairns, et al. (1978) (Table 6) indicate that daphnids are 

more resistant to copper at low temperatures in acute tests. Since such 

data were not available for other species or for longer tests, no generalizations could be made.fot criteria derivation, Chakoumakos, et al. (1979) 

and Howarth and Sprague (1978) (Tables 1 and 6) have reported that larger 

(10 to 30 g) rainbow trout are approximately 2.5 to 3.0 times more resistant 

to copper than juveniles. This factor is obviously a source of variation in 

Table 1. However, insufffcient data are available for other species to 

allow adjustment of *test results or on which to base criteria recomendations. An additional complicating factor is the general lack of knowledge 

of the range of sensitivity of various life stages of most invertebrate species, or the effects on susceptibility, of starvation and other stress factors under natural conditions. 
Lind, et al. (Yanuscrigt) (Table 1) and Brown et al, (Table 6)(1974) 

have shown quantitative relationships between the acute toxicity of copper 

and naturally occurring organic chelating agents. Although these relationships have been demonstrated for only a few species (Daphnia magna, fathead 

minnow, and rainbow trout), the effects shown should be generalizable 

through chemicai effects on cupric ion activity and bioavailability. Lind 

et al. (Yanuscript) measured the toxicity of copper in a variety of surface 

waters and found that total organic carbon (T.O.C.) is a more important 

variable than hardness, with Daphnia magna acute values varying 

approximate1.y 30-fold over the range of T.O.C. covered. Similar results 

were obtained with fathead minnows. This would indicate that the criteria 

should be adjusted upward for surface waters with T.O.C. significantly above 

the 2 to 3 mg/l usually found fn the waters used for toxicity tests. 

An exponential equatfon was used to describe the observed relationship 

of toxicity to hardness by performing a least squares regression of the 

natural logarithms of the acute values on the natural logarithms of hardness. Sufficient data were available for Daphnia maqna, Daphnia pulicaria, 

chinook salmon, cutthroat and rainbow trout, fathead minnows, and bluegills 

to show a correlation of acute toxicity and hardness. The slope of the regression equations ranged from 0.67 for chinook salmon to 1.34 for Daphnia 

magna with an arlthrnetlc mean of 0.94. The close agreement of the slopes 

and the hig)rly sfgnlffcant (p = 0.01) regressions In each case reflect the 

quality of tht toxicological data available and confirm the premise that the 

effect of hardness on the acute toxicity of copper is simflar for various 

aquatic animals. 

In the absence of the contradictory data, it is assumed that the hardness relationship holds for the acute toxicity of copper t0 all freshwater 

B-5 
aquatic animals. The mean slope (0.94) was fitted throl;gh the geomevic 

rrean toxicity value and hardness for each species to obtain a lcgarithmic 

intercept for each soecies. The species mean intercept, calculated as tne 

exponential of the logarithmic intercept, was used as a measure of rel'ative 

soecies sensitivlty to copper (Table 3). 

Daphnia pulicaria was found to be the most sensitive species. Two other 

daphnid soecies and the scud Gammarus pseudolimnaeus were only slightly less 

sensitive. Salmonids and the bluntnose minnows were nearly as sensitive as 

the daphnids, but fathead minnows and several other cyprinids were approximately 3 to 11 times more resistant. Bluegi 11s and other centrarchids are 

approximately 10 to 100 times more resistant than salmonids. 

A freshwater Final Acute Intercept of 0.29 ug/l was obtained for copper 

using the species mean acute intercepts listed in Table 3 and the calculation procedures described in the Guidelines. Thus the Final Acute Equation 

is ,(0.94[ln(hardness)]-1.23). 

The saltwater invertebrate data (Table 1) include investigations on 

three phyla: annelids, molluscs, and arthropods (crustaceans). The acute 

sensitivities of crustaceans ranged from 31 pg/l for Acartia tonsa (Sosnowski and Gentile, 1978) to 600 ug/l for shore crab, Carcinus maenus (Connors, 

1972). Adult polychaete worm +cute values ranged from 77 ug/l (Pesch and 

Morgan, 1978) to 480 *g/l (Jones, et al. 1976). Pesch and Morgan (1978) determined that the 96-hour KS0 for Yeanthes arenaceodentata increased from 

77 Ug/l in a flowing water system to 200 Ug/l in the presence of a sandy 

sediment. Jones, et al. (1976) irdicated that Nereis diversicolor exhibited 

a variable response to salinity ever a range of 5 to 34 g/kg with the 

greatest toxicity occurring at 5 gikg. The lowest reported acute value fcr 

the bivalve molluscs was 39 gg/l fzr the soft-shelled clam, +& arenaria 

3-6 
'Eisier, !977), ard the highest was 560 ug/l for the adult ?acific oyster, 

Grassostrea gigas (Okazaki, 1976). Eisler (1977) indicated that the sensitivity of Mya arenaria to coouer varied according to the seasonal tempera- 

'tJ?e -, with copper being at least 100 times more toxic at 22.C than at 4'C. 

The arthropods (crustaceans) were both the most sensitive invertebrate species tested, with an acute value of 31 Ug,'\ for Acartia tonsa (Sosnowski and 

Gentile, 1978), and the least sensitive of ali animals tested, with an acute 

value of 600 ug/l for larvae of the shore crab, Carcinus maenus (Connor, 

1972). Sosnowski, et al. (1979) showed that the sensitivity of field populations of Acartia tonsa to copper was strongly correlated with population 

density and food ration (Table 6), whereas cultured A. tonsa manifested a 

-- 

reproducible toxicalogical response to copper (Table 1) through six generations (Sosnowski and Gentile, 1978). Johnson and Gentile (1979) reported 

that lobster larvae appear to be twice as sensitive to copper as the adults. 

The acute values for saltwater fishes include data for four species and 

two different life hfstory stages (Table 1). Acute toxicity ranged from 28 

,,g/l for summer flounder embryos, Paralichthys dentatus (U.S. EPA, 1980) to 

510 Dg/l for the Florida pompano, Trachinotus carol inus (Birdsong and Avavit, 1971). The results of the acute tests on the embryos of summer and 

winter flounder were used in Table 1 because embryos of these species apparently are not resistant to copper and because other acute values are not 

available for these specfes. 

Studies err- the effect of salinity on the toxicity of copper indicate 

that it is more toxic to adult pomoano at 10 g/kg than at 30 g/kg (Birdsong 

aod Avavit 1971). Other species of saltwater fish were tested for sensitivity to copper, but the experimental conditions were not suitable for inclu8-7 
sion in either the acute or chronic tables; consequently, these data ;Irere 

placed in Table 6. Also, a number of scientists exposed anadromous species 

such as Atlantic and coho salmon to copper in freshwater. These data were 

utilized in deriving the freshwater criterion, but not the saltwater 

criterion. 

A Saltwater Final Acute Value of 22.9 ug/l was obtained for copper using 

the species mean acute values in Table 3 and the calculation procedures 

described in the Guidelines. 

Chronfc Toxicity 

The data base for chronic toxic'ty of copper to freshwater aquatic animals (Table 2) includes chronic values for four invertebrate and eleven fish 

specfes. Life cycle test results are available for two snails, Daphnia magna at three hardnesses, an amphipod, brook trout, bluntnose minnow, fathead 

- 

minnow at four hardnesses, and the bluegill. Early life stage tests have 

been conducted with several additional fish species, including channel catffsh at two hardnesses. The chronic values range from a low of 3.9 ug/l for 

early lffe stage tests wfth brook trout in soft water to 60.4 ug/l for a 

similar test with northern pike. Values for invertebrate species nearly 

overlap those for fish with a range of 6.1 to 29.0 ug/l. A series of tests 

wfth Oaphnfa magna in a hard pond water (Table 6) wfth unmeasured copper 

concentrations resulted in chronic values of about 49 ug/l. 

The data available concerning the effect of hardness on the chronic toxicfty of COQQW is somewhat nebulous. The total range of chronic values is 

3.9 to 60.4 ug/l (Table 2). which is much less than the range of 0.23 to 260 

*g/l 'for species mean acute intercepts (Table 3). This may be due to 

differences in the kinds and numbers of species and waters used in the two 

kfnds of tests, but it may also indicate that hardness affects chronic tox8-8 
iCity crf copper differently t?an it affects acute tOXic'ty. Indeed, ii 

chronic tests with Daphnia magna, Chapman, et al. (Manuscript) found that 

copper was less toxic at a medium hardness than at a low hardness but was 

most toxic at a high hardness (Table 2). They indicated that in the nigh 

hardness tests the daphnids probably ingested some precipitated copper. 

Also, some copper probably sorbed onto suspended food particles. These factors were not expected to ;aqait chronic toxicity to species whicn are not 

filter feeders, however. 

Sauter, et al. (1975) found that hardness affected the chronic toxicity 

of copper to channel catfish very little, if at all, and the four results 

available for brook trout do not show any consistent relationship. The four 

chronic tests with the fathead minnow also showed a consistent but small effect of hardness on chronic toxicity. The slope of 0.26 is not statistically significant and is much less than the acute mean slope of 0.94. A 

chronic value (Table 6) from a test conducted with the fathead minnow in a 

hard stream water contaminated with sewage effluent (8rungs, et al. 1976) 

was more than twice other values for this species. This probably indicates 

that the high levels of hardness, phosphate, and organic material reduced 

the chronic toxicity of* copper in this stream. On the other hand, a factor 

of two reduction in toxicity is rather small considering the much greater 

reductions that occur in acute toxicity of copper. 

Acute-chronic ratios for copper (Table 3) vary widely, even for tests 

with the Sam- species. The highest,.ratios (38 and '156) are for two of the 

more acutely resistant species, bluegills and Campeloma decisum (a snail). 

Ratios for three tests with 0. magna ranged from 1.2 to 7.3, and for four 

- 

tests with fathead minnows from 5.4 to 20. The more sensitive species have 

ratios below 4, whereas the less sens!tive species have ratios above 4. 

Also, the ratio seems to increase with hardness. 

B-9 
The available evidence seems to indicate that hardness affects the 

acute-chronic ratio but not the chronic toxicity of coooer. Chronic tests 

have been Conducted with quite a variety of aquatic animals and Dresent a 

good indication of the range of chronic sensitivity to copper. The 

Freshwater final Chronic Value for copper, derived from the species mean 

chronic values llsted in Table 2 using the calculatjon procedures described 

in the Guidelines, is 5.6 ug/l. 

The only chronic value reported (Table 2) for a saltwater species was 

that for the mysid shrimp, Mysidoosis bahia (U.S. EPA, 1980). The chronic 

toxicity of copper to this saltwater invertebrate was determined in a flowthrough life cycle exposure in which the concentrations of copper were 

measured by atomic absorption spectroscopy. Groups of 20 individuals were 

reared in each of ffve copper concentrations (control - 2.9 f 0.5 ug/l, 24.2 

2 7.0 ug/l, 38.5 2 6.3 ug/l, 77.4 f, 7.4 ugll, 140.2 2 11.8 ugll) for 46 days 

at 20'C and 30 g/kg salinjty. The biological responses examined included 

time of appearance of first brood, the number of spawns, mean brood size, 

and growth. The appearance of embryos in the brood sac was delayed for 6 

and 8 days at 77 ug/l and 140 ugil, respectively. The number of spawns recorded at 77 ~g/l was significantly (p < 0.05) fewer than at 38.5 ug/l. The 

number of spawns at 24 and 38 ug/l was not signiffcantly different from the 

control. Brood size was sfgnificantly (p < 0.05) reduced at 77 ugll but not 

at lower=concentratlons, and no effects on growth were detected at any of 

the coopw concentrations. Based upon reproductive data, adverse effects 

were observed at 38 ugll, but not at 77 ug/l, resulting in a chronic value 

of 54. ug/l. Using the acute value of 181 ugll, the acute-chronic ratio for 

this species is 3.4. 

The species mean acute-chronic ratios of 38 and 156 appear to be high 

(Table 3), but the other seven are al! ,dithin a factor af 10. The geometric 

3-10 
mean of :.+ese seven is 5.73. 1' the Saltwater Final acute Val3e 3; 22.3 

ug/7 is divided by the acute-chronic ratio of 5.78, a Saltwater Final 

Chronic 'Value of 4.0 ug/l is obtained, 

Dlant Effects 

Copper has been widely used as an algicide and herbicide for nuisance 

aquatic olants. Although it is known as an inhibitor of photosynthesis and 

plant growth, toxicity data on individual species (Table 4) are not numerous. The relationship of toxicity to water chemistry and the importance of 

the culttire medium on toxicity has only recently been recognized (Gachter, 

et al. 1973). 

Copper concentrations from 1 to 8,000 ug/l have been shown to inhibit 

growth of various plant species. Several of the values are near or below 

the chronic values for fish and invertebrate species, but most are much 

higher. No Final Plant Value can be obtained because none of the plant values were based on measured concentrations. 

For saltwater algae the concentrations 

cent reduction in photosynthesis or growth 

species of macro-algae and eight species of 

of copper which cause a 50 perare tabulated in Table 4 for one 

micro-algae. The most sensitive 

species were Thalassiosira pseudonana and Scrippsiella faeroense which were 

inhibited by 5 ug/l. 

Residues 

Bioconcentration factors 

2,000 for the alga Chlorella 

(Table 5) ranged from zero for the bluegill to 

regularis. Because copper is a required element for animal nutrition, the significance of copper residues has never 

been established, and few tests have been run for the purpose of determining 

bioconceotration factors. 

3-11 
Cspoer is 3~ essential eiefrent in the respiratory pi;merlts 2i sxe sa::- 

water invertebrates, especially Crustaceans, and plants have enzymes which 

csntain copper and are recessary for ohotosynthesis. However, copper is 

also Sioconcentrated in excess of any known needs by several saltwater soecjes (Table 5). The polychaete worm, Neanthes arenaceodentata, bioconcentrated copper 2,550 times (Pesch and Morgan, 1978), whereas in a series of 

measurements witn algae by Riley and Roth (1571) the highest reported concentration factor was 617 for Heterunastix Longifillis. 

The highest bioconcentration factors for copper are those for the bivalve molluscs. Shuster and Pringle (1969) found that the American oyster 

could concentrate copper 28,200 times after a 140day continuous exposure to 

50 ug/l. Even though the tissue of the oyster became bluish-green in color, 

mortalities at this level were only slightly higher than the controls. This 

amount of copper is not known to be harmful to man, but there have been instances recorded that oysters have been unmarketable because of their green 

appearance due 

Because no 

freshwater nor 

to high copper content. 

maximum permissible tissue concentration exists, neither a 

a saltwater Final Residue Value can be calculated. 

Miscellaneous 

The results of many additional tests of the effects of copper on freshwater aquatic organisms are listed in Table 6. Many of these are acute 

tests with non-standard durations for the organisms used. Many of the other 

acute tests-in Table 6 were conducted in dilution waters which were known to 

contain matvials which would significantly reduce the toxicity of copper. 

These reductfons were different from those caused by hardness, and not 

enough data exist to account for these in the derivation of the criteria. 

For example, Lind, et al. (Manuscript) conducted tests with Daphnia Pulicar3-12 
ia and fathead minnow in waters with concentrations of T.O.C. ranging up to 

34 mgll. Similarly, Geckler, et al. (1976) and Brungs, et al. (1976) conducted tests with many species in stream water which contained a iarge 

amount of effluent from a sewage treatment plant. Also, Wallen, et al. 

(1957) tested mosquitofish in a turbid pond water. Until chemical measurements which correlate well vrith the toxfcity 0.f copper in a wide variety of 

waters are identified and widely used, results of tests in unusual dilution 

waters, such as those in Table 6, will not be very useful for deriving water 

quality criteria. 

Longer exposures than the standard acute studies have been recorded in 

Table 6. Most noteworthy are the values reported for the bay scallop &- 

Jopecten irradfens (U.S. EPA, 1980). which suffered mortality and reduced 

growth at concentrations of S and 5.8 ug/l, respectively. Even though 

several studies have been reported on the sublethal effects on survival, 

growth, and reproductfon, the significance of these effects has yet to be 

evaluated. However, these studies do indicate existence of demonstrable 

lethal effects due to chronic exposure at very low concentrations of copper. 

Sumnary 

Acute toxicity data are available for 45 species of freshwater animals. 

The approximatqly 175 acute values range from 7.2 ug/l for Daphnia pulicaria 

in soft water to 10,200 vg/l for the bluegill in hard water. Statistically 

significant regressions of acute toxicity on water hardness are available 

for seven spccIcs, with toxicity decreasing as hardness increases. Additfonal data for several species indicate that toxicity also decreases with 

increases in alkalinity and total organic carbon. 

The range of acute values indicates that some of the more resistant species could survive in copper concentrations over 100 times that which would 

8-13 
be readily lethal to the more sensitive species. Among the more sensitive 

species are daphnids, scuds, midges, and snails which form the major focdwebs for both narm- and cold-water fishes. Concentrations of copper lethal 

to these sensitive organisms in soft water are only slightly above those 

chronically toxic to most fish and fnvertebrate species. 

Chronic values are available for I5 freshwater species, ranging from a 

low of 3.9 ug/l for brook trout to 60.4 ug/l for northern pike. Hardness 

does not appear to affect the chronic toxicity of copper. Fish and invertebrate species seem to be about eoually sensitfve to the chronic toxicity of 

copper. The two most sensitive species, bluntnose minnow and 5. pseudolimnea, are both important food organisms. 

Copper toxicity has been tested on a wide range of plant species, with 

results aoproximatfng those for animals. Complexing effects of the test 

media and a lack of good analytical data make interpretation and aoplication 

of these results dlfffcult. Protection of animal species, hawever, appears 

to offer adequate protection of plants as well, Coooer does not appear to 

bioconcentrate very much in the edible portion of freshwater aouatic soecies. 

The acute toxicity of copper to saltwater animals ranges from 17 ug/l 

for a calonoid cupepod to 600 ugll for the shore crab. A chronic lifecycle 

test has beer? conducted with the mysid' shrimp, and adverse effects were 

observed at 77 ug/1 but not at 38 ~g/l which resulted in an acute-chronic 

ratjo of 3.4. Several saltwater algal species have been tested, and effects 

were obsewcd between 5 and 100 ug/l. Oysters can bioaccumulate copper UP 

to 28,200 times, and become blu'sh-green, apparently without significant 

mortdlity. In long-term exposures, the bay scallop was kflled at 5 ug/?. 

CY?!WIA 

For total recoverable copper the criterion to protect freshwater aauatic 

life as derived using the Guidelines is 5.6 ugll as a 24-hour average, and 

3-14 
the concentration (in Vgll) should not exceed the numerical value given ?y 

e~0~g4~'n~hardness~~~1.23~ at any time. For example, at hardnesses of 50, 

100, and 200 mg/l as CaC03 the concentration of total recoverable copper 

should not exceed 12, 22, and 43 ugll at any time. 

For total recoverable cooper the criterion to protect saltwater aauatic 

life as derived using the Guidelines is 4.0 ug/l as a 24-hour average, and 

the concentration should not exceed 23 pg/l at any time.

Mammalian Toxicology and Human Health Effects 

INTRODUCTION 

Copper is widespread in the earth’s crust, and the extensive 

use of copper and its compounds by man since prehistoric times has 

added copper to the environment and the ecosystem in highly variable concentrations. 

From 1955 to 1958 the annual United States production of recoverable copper was about 900,000 metric tons. By 1975, the production had risen to 1,260,000 metric tons (D'Amico, 1959; U.S. 

Bur. Mines, 1976). The world trade in refined copper amounted to 

2,271,150 metric tons in 1973 (World Metal Statistics, 1974). 

Human exposure to copper can occur from water, food, and air, 

and through direct contact of tissues with items that contain copper. Copper is essential to animal life; consequently, abnormal 

levels of copper intake can range from levels so low as to induce a 

nutritional deficiency to levels so high as to be acutely toxic. 

EXPOSURE 

Ingestion from Water 

Water can be a significant source of copper intake depending 

upon geographical location, the character of the water (i.e., 

whether it is soft or hard), the temperature of the water, and the 

degree of exposure to copper-containing conduits. 

Schroeder, et al. (1966) place considerable emphasis on drinking water as a source of copper. They reported that the mean values 

of copper in human livers (56 cases) from Dallas, Denver, and Chicago varied from 410 to 456 μg/g of ash, and that the mean value 

C-1 
from Miami was 578 μg/g of ash1. The municipal water supplies of 

these cities each provided relatively hard potable waters with measured hardness ranging from 75 to 125 mg/l. On the other hand, 143 

human livers from seven cities with relatively soft waters ranging 

from 10 to 60 mg/l had mean levels of copper varying from 665 to 816 

μg/g of ash. Of the cases from soft water areas, 37.1 percent had 

hepatic copper of 700 or more μg/g of ash, compared with only 14.3 

percent of the samples from the hard water cities. Of the 56 individuals from three cities with the hardest water, only two showed 

such high values. Unfortunately no studies were made of cities 

with very hard water. 

lie in the ability of calcium or magnesium ions in hard water to 

Schroeder, et al. (1966) suggested that the higher copper 

levels in residents of cities with soft water might be due to the 

ability of soft water to corrode copper pipes and fittings, thereby 

increasing the intake of soluble copper. Another explanation may 

suppress the intestinal absorption of copper. 

Schroeder, et al. (1966) reported on the progressive increase 

of copper in water from brook to reservoir to hospital tap, and the 

considerable copper increment in soft water, compared with hard 

water, from private homes (Table 1). The authors found that 

the daily increment of copper ingested from soft water may amount 

to 10 to 20 percent of dietary intake. 

1 The values cannot readily be converted to total copper content 

present in liver on a wet weight basis since they were secured at 

autopsy. Information regarding the individuals from which samples 

came was minimal.

Zadjiznarkos (:367), on the csntrary, sugqested c,hat drinking 

water may be only a minor source of copper. He reported that the 

mean drinking water concentration of copper is 0.029 mg/l, which 

could nean a daily intake of 58 pg of copper in water, or 1 to 8 

percent of total daily intake if food intake is 3,200 ug of copper 

per day. 

It is probable that the difference in intakes estimated by 

Schroeder, et al. (1966) and Hadjimarkos (1967) is due to a difference in location. However, it is difficult to pinpoint local CODper concentrations in drinking water sources, since the only readily available information on concentrations of copper in stream 

water is from areas of 10,000 square miles or greater (Kopp and 

Kroner, 1968; Thornton, et al. 1966). 

Robinson, et al. (1973) in New Zealand have suggested that 

soft water used exclusively from the coldwater tap to make up daily 

beverages may add as much as 0.4 mg of copper per day per individual, but that if hot water from the same source is used for the 

same purposes, it would add at least 0.8 mg of copper per day to an 

individual's intake. 

The average concentration of copper in the United States water 

systems is approximately 134 ug/l [U.S. Department of Health, Education and Welfare (U.S. HEW), 19701. The highest concentration 

reported was 8,350 ug/l; a little over 1 percent of the samples exceeded the drinking water standard of 1 mg/l. 

The 1 mg/l copper standard was established not because of toxicosis but because of the taste which develops with higher levels 

of copper in the water (U.S. HEW, L970). It is most commonly exc-4 
ceeded in soft water that is acidic in nature; however, it is rare 

that the concentration of copper in drinking water is high enough 

to affect its taste or to produce toxicosis (McCabe, et al. 1970; 

Fed. water Quality Adm., 1968) l For this reason, regulatory aqenties have not treated copper in public water supplies as a siqnificant problem. In New York City, Copper is intentionally added to 

the water suPPlY to maintain a concentration of 0.059 mq/l in order 

to control algal growth (Klein, et al. 1974). 

prolonged contact of acidic beverages with copper conduits, 

such as occurred in earlier models of drink dispensing machines, 

may produce sufficient COppet concentration to cause acute copper 

toxicosis (see Acuter Subacute, and Chronic Toxicity section); however, because of taste problems, modern equipment does not contain 

copper conduits. 

The national impact of a water-borne contribution of copper is 

df f f icult to detect, predict, or evaluate because information is 

either absent or irretrievable. The current trend for recycling 

warta (animal wastes, sewage solids and liquids, channel dredging, 

and indurtrial warts) to the land offers very real possibilities 

that inbrlancw in organisms may unwittingly be created, because 

much wastes are comaonly high in trace element concentration0

9rrnufar CoPPer sulfate to the surface of Koover Reservoir, FrankC-S 
lin County, Ohio. Soluble and particulate cupric copper concentrations at several depths were measured by atomic absorption spectrophotometry for four days after application. The soluble cupric 

copper concentration decreased to near baseline values in 2 to 6 

hours when 0.2 or 0.4 qms of copper sulfate per square meter were 

added to the surface. Most of the copper sulfate was dissolved in 

tke first 1.7s meters of water column, and only 2 percent of the 

total copper sulfate reached the depth of approximately 4.5 meters. 

A concentration of 0.4 qms of copper per square meter controlled a 

diatom bloom. 

Ingestion from Food 

Levels Of copper in various foods are given in Table 2. Some 

foods, such as crustaceans and shellfish (especially oysters), 

organ meats (especially lamb or beef liver), nuts, dried legumes, 

dried vine and stone fruits, and cocoa, are particularly rich in 

copper. The copper content of these items can range from 20 vq/q to 

as high as 400 pg/q (McCance and Widdowson, 1947; Schroeder, et al. 

1966). fln an "as-cooked and as-served" basis, calves' liver, oysters, and many species of fish and green vegetables have recently 

been classed as unusually good source3 of copper (more than 100 ~q 

copper/100 kcal). 

High levels of copper may also be found in swine because of 

the practice, common in the United Kingdom and elsewhere, of feeding to swine diets that are high (up to 250 pq/q) in copper in order 

to increase daily weiqht gain. Levels of copper in swine liver 

vary greatly depending on the copper content of the feed. A high 

copper diet fed continuously until sLaughter may produce levels of

up to 400 to 600 ug/g in the liver. However, Swine will raGidly 

eliminate copper once it is removed from the diet. Sheep also acdumulate copper in direct proportion to the level of copper in the 

diet, but they eliminate excess copper very poorly [NRC-42, 1974; 

National Academy of Science (NAS), 1977: Barber, et al. 19781. 

Animal and industrial wastes (including sewage solids) commonly yield high concentrations of copper and other trace elements. 

The current emphasis on recycling these wastes may unintentionally 

supply excessive amounts of copper and these other elements to the 

soil. Such recycling could indirectly affect consumers Lf the 

yield of crops were reduced or if copper were increased in feed 

products (NILS, 1977). 

The National Academy of Science (1977) noted that the consumption of sheep or swine livers that are high in copper could result 

in excessive levels of copper, especially in baby foods where the 

actual amount of copper might exceed the copper requirements of 

very young children. 

Dairy products, white sugarr and honey rarely contain more 

than 0.5 pg copper/g. The nonleafy vegetables and most fresh 

fruits and refined cereals generally contain up to 2 ug/g. Cheese 

(except mental), milk, beef, mutton, white and brown bread, and 

many breakfast cereals (unless they are fortified) are relatively 

poor sources of.copper, i.e., they have less than 50 ug copper/100 

kcal [World Health Organization (WHO), 19731. 

The refining of cereals for human consumption results in significant losses of copper, although this loss is not so severe as 

it is for iron, manganeser and zinc. Levels of copper in wheat and 

wheat products are given in Tables 3 and 4.

Schroeder, et al. (1966) have suggested that since copper DCcurs widely in human foods, it is difficult to prepare a diet of 

natural foods that provides a daily copper intake of less than 2 

mg, the level that is considered to be adequate for normal copper 

metabolism (Adelstein, et al. 1956). 

Tompsett (1934) reported that the normal daily intake of copper from food appeared to be 2 to 2.5 my per day for human subjects. 

Daniels and Wright (1934) reported an average intake of 1.48 mg 

copper per day in young children, with a requirement of not less 

than 0.10 pg/kg of body weight per day. 

Most American and western European diets supply adults with 2 

to 4 mg of copper per day. This is evident from studies in England, 

New Zealand, and the United States. Lower estimates have been made 

for certain Dutch and poorer Scottish diets, while Indian adults 

consuming rice and wheat diets have been shown to ingest from 4.5 

to 5.8 mg of copper per day (Schroeder, et al. 1966). 

Scheinberg (1961) has contended that most adult diets supply a 

substantial excess of copper. Klevay, on the other hand, has suggested on the basis of recent food analyses that the copper content 

may be less than earlier analyses indicated and has cautioned that 

United States diets may not be adequdte to provide 2 mg of copper 

per day (Klevay, 1977; Klebay, et al. 1977). 

Dr. Walter Mertz in a personal communication reported that in 

1978 the analysis of diets of more than 20 individuals employed at 

the Institute of Nutrition of the U.S. Department of Agriculture, 

Beltsville, Md., showed that only two approached an intake of 2 mg 

of copper per day. The diets of these individuals included soft 

c-15 
drinks, water, and snacks, suggesting that food subjected to modern 

processing and preparation methods may be znuch lower in copper than 

was supposed based on earlier analyses, and that many individuals 

eating these foods may be receiving considerably less than the 2 mq 

of copper per day. 

Engel, et al. (1967) conducted studies on young girls which 

indicated that 2 P’; coppet/ cf die t was adequate for good nutrition. Petering, et al. il971) mention that the copper content of 

hair appears to be related to the age of the individual and suggest 

that the need for copper may differ between the sexes. 

Because of the essentiality of copper, the copper balance in 

newborn infants has been examined (Cave11 and Widdowson, 1964). It 

was noted that breast milk ranged from 0.051 to 0.077 mg/lOO ml and 

that total copper intakes of the babies ranqed from 0.065 to 0.1 

w/Wday l In the first week of life, some infants excreted more 

copper than was contained in the milk that they consumed. of 16 

babies, 14 were in negative balance. 

As a general statement it would appear that, at least in the 

United States, there is a greater risk of inadequate copper intake 

than of an excess above requirements. 

A bioconcentrationlfactor (BCF) relates the concentration of a 

chemical in aquatic animals to the concentration in the water in 

which they live. An appropriate BCF can be used with data concerning food intake to calculate the amount of cooper which might be 

ingested from the consumption of fish and shellfish. Residue data 

for a variety of inorganic compounds indicate that bioconcentration 

factors for the edible portion of most aquatic animals is similar, 

c-16 
except that for some compounds, bivalve molluscs (clams, oysters, 

scallops, and mussels) should be considered a separate group. An 

analysis (U.S. EPA, 1980) of data from a food survey was used to 

estimate that the per capita consumption of freshwater and estuarine fish and shellfish is 6.5 g/day (Stephan, 1980). The per capita consumption of bivalve molluscs is 0.8 g/day and that of all 

other freshwater and estuarine fish and shellfish is 5.7 g/day. 

A bioconcentration factor of zero was reported for copper in 

the muscle of bluegill sunfish (Benoit, 1975). Data are available 

for several species of saltwater molluscs:

If the values of zero and 290 are used with the consumption 

data, the weighted average bioconcentration factor for copper and 

the edible portion of all freshwater and estuarine aquatic organisms consumed by Americans is calculated to be 36. The geometric 

means for scallops, oysters, clams, and mussels are 3,708, 24,157, 

539, and 200, respectively, and the overall mean is 290. 

Inhalation 

The principal sourca of elevated copper levels in air is copper dust generated by copper-processing operations. However, since 

the economic value of copper encourages its capture from industrial 

processes, extraneous emissions are reduced. Other possible 

sources of copper in air may be tobacco smoke and stack emissions 

of coal-burning

not been considered a particularly hazardous indusbecause the conditions that would produce excessive 

concentrations of copper dust or mist in a particle size that could 

be absorbed and generate toxic effects are apparently quite rare. 

Investigations of Chilean copper miners have shown that liver and 

serum concentrations of copper are normal, despite years of exposure to copper sulfide and copper oxide dust, both of which are insoluble (Scheinberg and Sternlieb, 1969). However, workers can be 

exposed to excess concentrations of copper in any of its forms, and 

when this occurs, undesirable health effects can result. A 240 to 

28-hour illness characterized by chills, fever, aching muscles, 

dryness in the mouth and throat, and headache, has been noted where 

workers are exposed to metal fumes within closed areas zis a result 

of the welding of copper structures (McCord, 1960). 

C-18 
The U.S. Occupational Safety and Health Administration (OSHA) 

has adopted standards of exposure to airborne copper at work. The 

time-weighted average for 8-hour daily exposure to copper dust is 

limited to 1 mg/m3 of air. The standard for copper fume was changed 

in 1975 to 0.2 mg/m3 (Gleason, 1968; NAS, 1977). 

In 1966, a National Air Sampling Network survey showed that 

the airborne copper concentrations were 0.01 and 0.257 pg/m3 in 

rural and urban communities, respectively (Natl. Air Pollut. Control Admin., 1968). Even near copper smelters, where high levels 

(1 to 2 ug/m3) are reached, the dose of metal that would be acquired 

through inhalation of ambient air would comprise only about I percent of the total normal daily intake (Schroeder, 1970). 

Generally speaking, inhalation of copper or copper compounds 

is of minor significance compared to other sources, e.g., copper in 

foods, drinking water, and other fluids, and use of copper for medical purposes. 

Dermal 

Copper toxicity has resulted from the application of copper 

salts to large areas of burned skin or from introduction of copper 

into the circulation during hemodialysis. The source of the copper 

in hemodialysis may be the membranes fabricated with copper* the 

copper tubing, or the heating coils of the equipment. Copper stopcocks in circuits can also cause potentially hazardous infusions of 

copper (Holtzman, et al. 1966; Lyle, et al. 1976). 

Studies with monkeys indicated that copper used as dental 

fillings and placed in cavities in the deciduous teeth of the monkey caused more severe pulp damage than any of the other materials 

c-19 
studied. This is additional evidence that tissues exposed directly 

to copper or copper salts will suffer adverse effects due to the 

direct absorption of the copper by the tissues (Yjor, et al. 1977). 

Recent papers from Australia (Walker, 1977: Walker, et al. 

1977) suggest the possibility of copper absorption through the skin 

as a result of perspiration action on the copper bracelet, sometimes worn as treatment for arthritis, although the therapeutic 

value of this has little support. 

Concern has been directed toward the absorption of copper as a 

result of the use of the intrauterine device (IUD) as a contraceptive measure (NAS, 1977). Analysis of IUDs that have been in utero _Ifor months to years shows that about 25 to 30 mq of copper are lost 

each year. Some of the metal is excreted with endometrial secretions. Experimental evidence to date does not indicate that use of 

an IUD results in harmful accumulations of copper (see Absorption 

section for additional information). 

PHARMACOKINETICS2 

Absorption 

Tracer studies provide the basis for the conclusions that most 

absorption in man takes place in the stomach and the duodenum. 

Copper absorption appears to be regulated by the intestinal mucosa, 

and maximum copper levels occur in the blood serum within one to 

three hours after oral intake.

Much of the information on copper absorption in humans has 

come from studies of patients with Wilson’s disease. studies conducted with these patients using radioactive copper indicate that 

about one-half of the copper in the diet is not absorbed but is excreted directly into the feces. The average absorption in these 

individuals has been reported to be approximately 40 percent 

(Sternlieb, 1967; Strickland, et al. i972a). Investigations by 

Cartwright and Wintrobe (1964a) indicated that the daily intake of 

copper in Wilson’s disease patients was 2 to 5 mq, of which 0.6 to 

1.6 mq were absorbed, 0.5 to 1.2 mq were excreted in the bile, 0.1 

to 0.3 mg passed directly into the bowel, and 0.01 to 0.06 mg appeared in the urine. 

Information from these studies indicates that absorbed copper 

is rapidly transported to blood serum and taken up by the liver, 

from which it is released and incorporated into ceruloplasmin. Any 

copper remaining in the serum is attached to albumin or amino acids 

or is used to maintain erythrocyte copper levels (Weber, et al. 

1969; Bearn and Runktl, 1954, 1955; Beckner, et al. 1969; Bush, et 

al. 1955; Jensen and Ramin, 1957). 

Estimates of the amount of the copper that is actually absorbed by normal individuals vary considerably and must be considered inconclusive. The values obtained have ranged from as low as 

15 percent ta as high as 97 percent (weber, et al. 1969), although 

it seems probable that subjects having these extreme values were 

not in a steady state. The uncertainty of these values is confounded by the lack of accurate information regarding the excretion 

of copper in its various forms by way of the biliary system. Even 

c-21 
less information is available regarding the reabsorption of copper 

or copper compounds from the intestine after they have been excreted in the bile. Most of the values that have been obtained with 

normal subjeats lsuqqest that 40 to 60 percent of the dietary copper 

is absorbed (Van Ravenstcyn, 1944: Cartwright and Wintrobe, 1964a; 

Bush, et al. 1955; Matthews, 1954: Weber, et al. 1969: Strickland, 

et al. 1972a,b; Sternlieb, 1967). 

Animal studies have shown that copper is absorbed by at least 

two mechanisms, an energy-dependent mechanism and an enzymatic 

mechanism (Crampton, et al. 1965), and that many factors may interfere with copper absorption, including competition for binding 

sites as with zinc, interactions with molybdenum and with sulphates, chelation with phytates, and the influence of ascorbic acid. 

Ascorbic acid will aggravate copper deficiency by decreasing copper 

absorption. In cases of excess copper intake, ascorbic acid can 

reduce the toxic effects (Gipp, et al. 1974: Hunt, et al. 1970: 

Voelker and Carlton, 1969). 

Studies with laboratory animals have shown that once copper 

enters the epithelial cells, it is taken up by a cellular protein 

similar to liver metallothionein (Evans, et al. 1973; Evans, 1973; 

Starcher, 1969). Absorbed copper is bound to albumin and transported in the plasma. Approximately 80 percent of the absorbed 

copper is bound in the liver to metallothionein. The remaining 

copper is incorporated into compounds such as cytochrome-c-oxidase 

or is sequestered by lysosomes (Bearn and Kunkel, 1954, 1955) l 

Little information is available concerning absorption of copper 

into the lymphatics, although in pathological conditions this may 

be significant (Trip, et al. 19691. 

c-22 
Several studies have been conducted on humans and laboratory 

animals concerning absorption of copper as a result of the use of 

copper IUDs. Studies with the IUD in rats have suggested that as 

much as 10 to 20 mg of copper may be absorbed (Oreke, et al. 1972). 

This amount, which is small compared to the dietary copper usually 

ingested, may or may not be metabolized and excreted by the same 

homeostatic mechanisms that operate with ingested copper. If an 

IUD were used for many decades and the absorbed copper were retained, it would result in amounts of copper similar to those retained from dietary copper by patients with Wilson's disease. Such 

levels could result in chronic toxicosis. 

Japanese investigators (Okuyama, et al. 1977) have compared 

effects of using the IUD with copper and the IUD without copper in 

two groups of womenr using a third group as controls. Pregnant 

women with an IUD in place were also examined. No significant dif& 

ference was found in the endometrial copper levels in the three 

groups. There was a tendency toward an increase above controls in 

the endometrial level of copper during the secretory phase in those 

women using the IUD wfth or without copper. No significant difference was found between women who had used an IUD more than 13 months 

and those who had used it less than 13 months. The copper content 

of the chotion and the decidua of the pregnant women with IUDs in 

place did notdiffer from the levels noted in pregnant women without IUDs. Apparently, the long-term use of copper-containing IUD3 

did not lead to an accumulation of copper in the uterus. 

Tamaya, et al. (1978) have studied the effect of the copper 

IUD on the histology of the endometrium in the proliferative and

Distribution 

The amount and distribution of copper in body tissues varies 

with sexr ager and the amount of copper in the diet. Copper content 

of fat-free tissues of most animals ranges upward from about 2 

w/g l The highest concentrations of copper in both animal and 

human tissues are found in the liver and the brain, with lesser 

amounts in the heart, the spleen, the kidneys, and blood (Cartwright and Wintrobe, 1964a,b: Smith, 1967; Schroeder, et al. 1966). 

Some tissues are very high in copper, e.g., the iris and the choroid of the eye , which may contain as much as 100 ~g/gm (Bowness and 

Morton, 1952; Bowness, et al. 1952). 

Estimates of the total amount of copper in a 70 kg man have 

ranged from 70 to 120 mg. Approximately one-third of body copper 

is found in the liver and the brain, one-third is found in the musculature, and the remaining one-third is dispersed in other tissues. It has been estimated that, on the average, about 15 percent 

of the total body copper is contained in the liver (Tipton and 

Cook, 1963: Sumino, et al. 1975; Sass-Kortsak and Bearn, 1978). 

The relatively high percentage of liver copper is related to the 

liver’s function as a storage organ for conper and a8 the only site 

for the synthesis and release of ceruloplasmin, the most abundant 

copper protein in the blood. 

In the brain, the striatum and both components of the cortex 

(gray matter) have the highest copper content, with the cerebellum 

(white matter) being the lowest (Hui, et al. 1977; Cumings, 1948: 

Earl, 1961). The brain appears to be the only tissue in which there 

is a consistent increase in copper content with age. clther tissues 

appear to be under a homeostatic control. 

c-25 
Copper levels in hair vary widely with respect to age, sex, 

and other factors, and therefore have little meaningfulness in 

evaluating copper levels in man (Underwood, 1977). Rowever, Jacob, 

et al. (1978) have suggested that the copper in hair may be useful 

in evaluating the total liver content of copper. Engel, et al. 

(1967) surveyed over 180 adolescent girls in the 6th to 8th grades 

for dietary intake and nut:iticnal status. They found that the 

mean concentration of copper in hair samples was 31 2 23 vg/g. No 

significant difference was found between girls who had experienced 

menarche and those who had not. 

Levels of copper in the blood of normal adults average 103 

ug/lOO ml of blood. The amount of copper in blood serum can range 

widely from S ug/lOO ml to 130 pg/lOO ml. In practically all species, copper deficiency is first manifested by a slow depletion of 

body copper stores, including the blood plasma, eventually resulting in a severe anemia identical to that caused by iron deficiency 

(Cartwright, et al. 1956). 

Both the plasma and the erythrocytes have two pools of copperr 

a labile pool and a stable pool, which contain approximately 40 and 

60 percent respectively, of the copper in the blood (Bush, et al. 

195s). Ceruloplasmin represents the predominant portion of cooper 

in the serum pool. There appears to be little or no interchange 

between ceruloplasmin copper and other forms of copper in the blood 

stream (Sternlieb, et al. 1961). Mondorf, et al. (1971) indicate 

that the blood contains an average of 30 ug of ceruloplasmin/lOO ml 

of blood. This is in reasonable accord with accepted levels of 

copper in the blood of normal adults (approximately 103 ug total 

C-26 
copper/100 ml of blood). White blood cells contain a small arr.cunt 

of copper f about one-fourth the concentration in erythrocytes 

(Cartwright, 1950). 

The distribution of copper in the fetus and in infants is 

quite different from that in the adult. The percentage of copper 

in the body increases progressively during fetal life (Shaw, 1973). 

Chex, a% al. (1978) found that concentrations of copper in amniotic 

fluid increased between the 26th and 33rd weeks of pregnancy, but 

that there did not appear to be a correlation between maternal and 

fetal copper Concentrations. 

At birth, the liver and spleen contain about one-half the copper of the whole body (Widdowson and Spray, 1951). A newborn infant contains about 4 mg/kg as compared to approximately 1.4 mg/kg 

in the 70 kg man (Widdowson and Dickerson, 1964). The liver of the 

newborn has approximately 6 to 10 times the amount of copper in the 

liver of an adult man on a per gram basis (Bruckmann and Zondek, 

1939; Nusbaum and Zettner, 1973; Widdowson, et al. 1951). 

The concentration of copper in the serum of newborn infants is 

significantly lower than in 6- to 120year-old healthy children, but 

by five months of age the serum concentration of copper is approximately the same as in older children. Ther.e is no difference between copper levels in male and female infants, although breast-fed 

infants see, to have somewhat higher copper levels by one month 

than bottle-fed infants (Ohtake, 1977). The liver copper content 

of the fetus is several times higher than maternal liver copper 

(Seeling, et al. 1977). 

C-27 
Hetabolism 

The copper content of red blood cells remains remarkedly constant, but the plasma copper is subject to striking changes asgociated with the synthesis and release of ceruloplasmin, which fs 

the most abundant copper protein that responds to deficiencies or 

excesses (Gubler, et al. 1953: Lahey, et al. 1953). 

Some 20 mammalian copPer proteins have been isolated, but at 

least three are identical and others have more than one name. Most 

of this information has come from animal studies, and its applicability to humans is uncertain. Evans (1973) and others have reviewed this subject (Mann and Keilin, 1938t Osborn, et al. 1963; 

Morell, et al. 1961; Sternlieb, et al. 1962). 

Copper plasma levels during pregnancy may be two to three 

times the normal nonpregnant level. This is almo8t entirely due to 

the increased synthesis of ceruloplasmin (Henkin, et al. 1972; 

Markowitz, et al. 1955; Scheinberg, et al. 1954). The source of 

this copper appears to be the maternal liver. The increase in 

maternal plasma copper levels appears to be assooiated with estrogen, since either sex receiving estrogen shows an increase in copper level of the plasma (Elsner and Hornykiewicz, 1954: Gault, et 

al. 1966: Humoller, et al. 1960: Russ and Raymunt, 1956). 

The use of oral contraceptives causes a marked increase in 

serum copper lavels that may be greater than those observed during 

pregnancy (Oster and Salgo, 1977; Smith and Brown, 1976; Tatum, 

1974). 

Infant levels of serum copper are low at birth but promptly 

increase due to the synthesis of ceruloplasmin by the infant’s 

liver (Henkin, et al. 1973; Schorr, et al. 1958). 

C-28 
There are two inherited diseases that represent abnormal copper metabolism, Menkes' disease and Wilson’s disease. Yenkes' disease is a progressive brain disease caused by an inherited sexlinked recessive trait. It is often referred to as the “kinky 

hair” disease or "steely hair" disease (Danks, et al. 1972). The 

primary characteristic of Menkes' disease appears to be a diminished ability to transfer copper across the absorptive cells of the 

intcstinalmucosa (Danks, et al. 1972, 1973). The general symptoms 

of the disease are similar to those observed in animals suffering 

from copper deficiency (Oakes, et al. 1976). The prospects for 

more effective therapeutic measures as a result of early diagnosis 

appear to be limited. 

Wilson*s disease, which has also been designated “hepatolent fcular degeneration, a is caused by an autosomal recessive trait 

(Beam, 1953). The disease is actually a copper toxicosis with 

abnormally high levels of copper in the liver and brain (Cumings, 

1948). Symptoms include increased urinary excretion of copper 

(Spillane, et al. 1952: Porter, 1951), low serum copper levels due 

to low ceruloplasmin (Scheinberg and Gitlin, 1952), decreased intestinal excretion of copper, and occurrence of Kayser-Fleischer 

rings due to excessive accumulation of copper around the cornea. 

If therapy witb d-penicillamine is instituted during the early 

phases of Wflronls disease, it can assure a normal life expectancy, 

especially when accompanied by a low-copper diet (Deias, et 31. 

1971: Sternlieb and Scheinberq, 1964, 1968; WaSshe, 1956). 

Other abnormalities of copper metabolism are primarily associated with low levels of copper. Ayoocupremia, which is defined as 

c-29 
80 'Jg or less of copper/100 ml (Cartwright and Wintrobe, 1964a), 

usually refers to a low ceruloplasmin level. In most cases it is 

probably due to a dietary deficiency of copper or to a failure to 

synthesize the apoenzyme of ceruloplasmin (Kleinbaum, 1963). HYPOcupremia can also result from malabsorption that occurs during a 

small bowel disease (Sternlieb and Janowitz, 1964). 

Hypercupremia, abnormally hiqh levels of copper, occurs with a 

number of neoplasms (Delves, et al. 1973; Herring, et al. 1960; 

Goodman, et al. 1967; Janes, et al. 1972). Elevated serum copper 

levels occur in psoriasis (Kekki, et al. 1966; Molokhia and Portnoy, 1970). 

It is well recognized that copper is necessary for the utilization of iron. Much of this work has been done in animals, and the 

subject is well covered by Underwood (1977). It appears that ceruloplasmin is essential for the movement of iron from cells to plasma (Osaki, et al. 1966). Reticulocytes from copper-deficient animals can neither pick up iron from transferrin normally nor synthesize heme from ferric iron and protoporphyrin at the normal rate 

(Williams, et al. 1973). 

The ratio of copper to other dietary components, e.q.# zinc, 

iron, sulfate, and molybdenum, may be almost as important a3 the 

actual level of copper in the diet in influencing the metabolic 

response of mammalian species (Smith and Largon, 1946). The cardiovascular disorder "falling disease", reported by Bennetts, et 

al. (1942), is associated with a copper deficiency in cattle. Similar conditions have been observed in pigs and chicken3 (O'Dell, et 

al. 1961; Shields, et al. 1961). In this disorder the elastic tisc-30 
sue of major blood vessels Is deranged, markedly reducing zhe tensile strength of the aorta. This appears to be associated with a 

biochemical lesion, the reduced activity of lysyl oxidase, a copper-requiring enzyme necessary for elastic tissue formation and 

maintenance (Hill, et al. 1967). 

Evans has discussed the metabolic disorders of copper metabolism including nutriticnal disorders, inborn order errors of proper 

homeostasis, and disorders due to the lack of copper-requiring enzymes (Evans, 1977). 

Particular attention has been given to the role of copper as 

associated with cardiovascular diseases (Vallee, 1952; Adelstein, 

et al. 1956). More recently there has been considerable interest 

in the role of copper and its ratio to zinc as a factor in the level 

of cholesterol and cholesterol metabolism as it nay relate to ischemic heart disease (Klevay, 1977). It has been suggested that a 

low copper-high zinc ratio may result in an increased level of 

cholesterol, particularly that part of the blood cholesterol in the 

serum low density lipoprotein whic.h has been associated with increased susceptibility to ischemic heart disease (Allen and Klevay, 

1978a,b; Petering, 1974; Lei, 1978; Klevay, et al. 1977). In a 

different context, Barman (1970) has suggested that copper in the 

diet in excess of needs may result in free radicals that cause adverse effects fn the cardiovascular system. 

Excretion 

It has been noted that perhaps 40 percent of dietary copper is 

actually absorbed (Cartwright and Wintrobe, 1964a). These estimates are largely based on the difference between oral intake and 

c-31 
fecal excretion. S’rinary excretion of copper ?Lays a very minor 

role. The fecal excretion represents unabsorbed dietary copper and 

the copper that is excreted by the biliary tract, the salivary 

glands, and the gastric and intestinal mucosae (Gollan and Deller, 

1973). It should be noted that some of the excreted copper is reabsorbed in the course of its movement down the intestinal tract. 

Some loss of copper may occur by way of sweat and in the female 

menses. 

One of the principal routes of excretion is by way of the 

bile; however, because of the difficulty in studying biliary excretion in normal subjects, the evidence for quantitative values of 

copper excretion by this route is fragmentary. Cartwr ight and Wintrobe (1964a) suqqest that 0.5 to 1.2 mq per day is excreted in the 

bile. This is in reasonable accord with the report (Frommer, 1974) 

that excretion was approximately 1.2 mq/day in ten control subjects. It is possible that very little of the copper excreted in 

the bile is reabsorbed (Lewis, 1973). 

Some copper (approximately 0.38 to 0.47 mq/day) is excreted in 

the saliva, but there is little evidence as to whether this copper 

is or is not absorbed in the intestine (DeJorge, et al. 1964). 

It is possible that the gastric secretion of copper approximates 1 mq of copper per day, but there is very little published 

information on this subject (Gollan, 1975). 

The amount of copper excreted in the urine is small. Estimates range from 10 to 60 ug/day and average 18 ug/day (Cartwright 

and Wintrobe, 1964a; Zak, 1958). It is possible, of courser that 

copper may be reabsorbed from the kidney tubules (Davidson, et al. 

1974). 

C-32 
Studies in New Zealand conducted on young women with a copper 

intake of 1.8 to 2.09 mg/day showed an excretion in the feces of 

between 65 and 94 percent of the intake. The urinary excretion 

amounted to 1.7 to 2.2 percent of the intake (Robinson, et al. 

1973). 

Under some conditions a considerable amount of copper may be 

lost through sweat, perhaps as much as 1.6 mg of copper per day or 

about 45 percent of the total dietary intake (Consolazio, et al. 

1964). 

There is very little information on the loss of copper by way 

of the menstrual flow, but an average value of 0.11 f 0.07 mg per 

period seems reasonable (Ohlson and Daum, 1935; Leverton and Binkley, 1944). 

Sternlieb, et al. (1973) note that 0.5 to 1.0 mg of copper is 

catabolized daily by the adult liver, and about 30 mg of ceruloplasmfn, which contains 0.3 percent copper, is excreted into the 

intestine (Waldmann, et al. 1967). The copper excreted into the 

intestine in the bile may not be readily available for reabsorption 

because it is bound to protein: the copper found in the feces seems 

to come from various secretions, as well as the copper that is not 

absorbed from food (Gollan and Deller, 1973). 

In summary it may be said that most copper is excreted by way 

of the Uliary system with additional amounts in sweat, urine, 

saliva, gastric and intestinal mucosae, and menstrual discharge. 

Examination of the pharmokinetic data points up the fact that 

the biological half-life of copper is very short. This provides 

significant protection against accumulations of copper even with 

intakes considerably above levels considered adequate. 

c-33 
EFFECTS 

Acute, Subacute, and Chronic Toxicity 

Copper toxicity produces a metallic taste in the mouth, nausea, vomiting, epigastric pain, diarrhea, and depending on the 

severity, jaundice, hemolysis, hemoglobinuria, hematuria, and oliguria. The stool and saliva may appear green or blue. In severe 

cases anuria, hypotension, and coma can occur. 

Toxic levels of copper ingested are promptly absorbed from the 

upper gut, and the copper level in the blood is rapidly increased, 

primarily because of its accumulation in the blood cells. Hemolysis occurs at high copper levels. A high level in the blood can 

also result from absorption through the denuded skin, as when applied to burns, because of dialysis procedures, or because of exchange transfusions. The hemolysis is due to the sudden release of 

copper into the blood stream from the liver that has been damaged 

by an increasing load of copper and is unable to utilize the copper 

in the synthesis of ceruloplasmin, which in turn can be excreted by 

way of the biliary system (Chuttani, et al. 1965; Bremner, 1974: 

Cohen, 1974; Deiss, et al. 1970; Roberts, 1956; Bloomfield, et al. 

1971; Ivanovich, et. al. 1969; Bloomfield, 1969). 

Chatterji and Ganguly (1950) describe a nonfatal type of copper poisoning in which the symptoms are laryngitis, bronchitis, 

intestinal colic with catarrh, diarrhea, general emaciation, and 

anemia. 

Burch,. et al. (1975) have estimated that the toxic intake 

level of inorganic copper for an adult man is greater than 15 mg per 

dose. The vomiting and diarrhea induced by ingesting small quantic-34 
ties of ionic copper generally protect the patient from the serious 

systemic toxic effects which include hemolysis, hepatic necrosis, 

gastrointedtinal bleeding, oliguria, azotemia, hemoglobinuria, 

hematuria, proteinuria, hypotension, tachycardia, convulsions, or 

death (Chuttani, et al. 1965; Davenport, 1953). 

Because most of the information about acute copper toxicity in 

humans has come from attempts at suicide or from the accidental 

intake of large quantities of copper salts, the information about 

the changes occurring with acute toxicity are meager. 

Acute copper poisoning does occur in man when several grams of 

copper sulfate are eaten with acidic food or beverages such as vinegah carbonated beverages, or citrus juices (Walsh, et al. 1977). 

Some cases of acute poisoning have occurred when tablets containing 

copper sulfate were given to children (Forbes, 1947). 

When carbonated water remains in copper check valves or drinkdispensing machines overnight, the copper content of the first 

drink of the day may be increased enough to cause a metallic taste, 

nausear vomiting, epigastric burning, and diarrhea (Hooper and 

Adams, 1958). Drinks that are stored in copper-lined cocktail 

shakers or vessels can have the same effect (Pennsylvania Morbidity 

and Mortality Weekly Reports, 1975: McMullen, 1971). 

Salmon and Wright (1971) have reported the possibility of 

chronic comr poisoning as a-result of water moving through copper 

pipes. They-document a case in which a family moved into a house in 

North London with a hot water system entirely composed of copper. 

The water was stored in a 40-gallon copper tank which reached a 

temperature of 93OC at night. The family used hot water for all 

c-35 
cooking and beverages. After two rr,ontfis, the electric kettle was 

coated inside with a thick green film of the copper complex. The 

child in the family was admitted to the hospital after five weeks 

of behavior change, diarrhea, and progressive marasmus. When it 

was first seen, the clinical picture was that of "pink" disease 

with prostration, misery, red extremities, hypotonia, photophobia, 

and peripheral edema. The liver was palpable 2 cm below the costal 

margin. The serum copper level was 286 pg/lOO ml, compared to a 

normal range of 164 2 70 ug/lOO ml. Analysis of water in the home 

found 350 pg/l of copper in the cold water and 790 ug/l of copper in 

the hot water. Cold and hot water levels in the hospital were 40 

and 300 ug/l, respectively, and in North London the values were 80 

and 160 ug/l. 

Walker-Smith and Blomfield (1973) treated the male infant described in the preceeding paragraph, who had received high levels 

of copper from contaminated water over a period of three months, 

with d-penicillamine and prednisolone. The infant made a slow recovery. The method of Eden and Green (1940) was used to determine 

copper levels. It is possible that the infant was exhibiting Wilson's disease and responded to the appropriate treatment. 

Eden and Green (1940) reported on a male infant 'who received 

high levels of copper frosn contaminated water ingested over a period of three months. The result was chronic copper poisoning. 

Treated with d-penicilliamine and prednisolone, the infant made a 

slow recovery. 

In general, however, the problems associated with high levels 

of copper in drinking water are more or Less controlled because of 

C-36 
(1) taste (since high levels of copper in water produce a metallic 

taste), and (2) cosmetic considerations (since water with high copper content develops a surface scum due to the formation of insoluble copper compounds). 

Chronic toxicity has been studied in animals, and there appears to be a wide variation in the tolerance of different species 

for high levels of copper in the diet. Sheep are very susceptible 

to high copper intakes, whereas rats have been shown to be very 

resistant to the development of copper toxicity. 

Swine will develop copper poisoning at levels of 250 pg of 

copper/g of diet unless zinc and iron levels are increased. Suttle 

and Mills (1966) have studied dietary copper levels ranging up to 

750 pg/g in the diet of swine. Toxicosis does develop with hypochromic microcytic anemia, jaundice, and marked increases in the 

liver and serum copper levels as well as serum aspartate amino 

transferase. These signs of copper toxicosis in swine can be eliminated by including an additional 150 pg of zinc and iron/g in 

diets containing up to 450 ug of copper/g; the addition of even 

more zinc and iron, 500 to 750 pg/g, will overcome the effects of 

750 ug of copper/g of diet. 

Chronic oral intake of copper acetate in swine and rats can 

produce a condition comparable to hepatic hemosiderosis in man 

(Mallory an& Parker, 1931). Some question exists as to whether 

hemosiderosis in man is a result of copper toxicity, because people 

consuming comparatively high levels of copper do not develop this 

condition regularly. 

c-37 
Sheep are quite susceptible to high levels of copper in the 

diet. Copper levels of 35 ug/g of feed have resulted in toxicity 

when fed over a period of nine months to one year (Fontenot, et al. 

1972). Cattle are much more resistant to copper in the diet; 2 g of 

copper sulfate given daily did not produce toxic reactions (Gunningham, 1931). 

It is well known that with ruminant animals, molybdenum and 

sulfate interact with the copper. Cooper toxicity is counteracted 

by inclusion of molybdenum and sulfate in the diet of ruminants 

(Dick, 1953: Kline, et al. 1971; wahal, et al. 1965). 

Synergism and Antagonism 

There is some evidence that copper may increase the mutagenic 

activity of other compounds. Using strain TAlOO of Salmonella 

typhimurium, Omura, et al. (1978) studied the mutagenic actions of 

triose reductone and ascorbic acid. They found that the addition 

of the copper to triose reductone at a ratio of l:l,OOO lowered the 

most active concentration of the triose reductone to 1 mM from 2.5 

to 5 ref. 

Another enediol reductone, asborbic acid, had no detectable 

mutagenic action by itself, but a freshly mixed solution of 5 mM of 

ascorbic acid and 1 or 5 UM of cupric copper had an effective mutagenic action. Ascorbyl-3-phosphate had no mutagenic function even 

in the presence of cupric copper. The investigators suggested that 

it was the enediol structure in the reductones that was the essential for mutagenicity. 

In the Acute, Subacute, and Chronic Toxicity section, it was 

pointed out that the dietary levels of zinc and iron are as imporC-38 
tant as the level of copper in determining the toxic level of 

copper . 

Teratoqenfcfty 

There is very little evidence in the literature to suggest 

that copper has a teratoqenic effect in either animals or humans. 

Mutagenicity 

No data were found to suggest that copper itself has a mutagenic effect in either animals or humans: however, one report 

exists suggesting that copper may increase the mutagenic activity 

of other compounds (see Synergism and Antagonism section). 

Carcinoqeniclty 

There is very little evidence in the literature to suggest 

that copper has a carcinogenic effect in either animals or humans. 

Pimental and Marques (1969) noted that vineyard workers in France, 

Portugal, and southern Italyr exposed to copper sulfate sprays 

mixed with lime to control mildew, developed qranulomas in the 

liver and malignant tumors in the lung (Pimental and Menezes, 1975; 

Villar, 1974). Because of the route of expoaure, quantitative 

estimates are, at best, speculative. 

It has been noted earlier that the conditions in industry that 

would produce excessive concentrations of copper as a dust or a 

mist with particle sizes that would result in toxic effects if the 

copper were absorbed, are apparently quite rare. Some investigators have suggested that lung cancer, which is prevalent in copper 

smelter workers, is actually due to the arsenic trioxide in the 

dust and that the copper itself did not play any etiologic role in 

the development of the cancer (Xuratsune, et al. 1974; Lee and 

c-39 
Fraumeni, 1969; Yilham and Strong, 1974; Tokudome and Kuratsune, 

1976). 

Some studies have reported that, with the development of various tumors, the copper content in both blood and the tumor tissue 

is likely to increase, although this is not always the case (Pedrero and Kozelka, 1951; Dick, 1953; Kline, et al. 1971: Wahal, et 

al. 1965). Kowever, when an increase occurs, it appears to be a 

result of an inflammatory response or stress rather than any direct 

causative relationship. 

Polish workers (Legutko, 1977) have suggested that the copper 

level of the serum is a particularly sensitive indicator of the 

clinical condition and effectiveness of treatment of lymphoblastic 

leukemia in children, but again no particular relationship to the 

development of the leukemia is indicated. 

Russian scientists (Bezruchko, 1976) have also studied the 

copper and ceruloplasmin in patients with cancer and noted that the 

levels of both ceruloplasmin and copper were increased in metastatic cancer of the mammary gland, in skin melanoma, and in ovarian 

cancer. The serum levels of ceruloplasmin increased 27, 20, and 44 

percent, respectively, for those tumors, and the copper increased 

by 41, 35, and 51 percent, respectively, for those same tumors as 

compared with normal tissue. Again, no correlation was found between the tumor and copper as a causative agent. 

Workers in Hong Kong (Fang, et al. 1977) have been investigating copper concentrations in cases of esophageal cancer in both 

humans and animals. They report that serum copper is increased 

slightly and that this is paralleled by a decrease in zinc content. 

c-40 
In 3ummaryl it must be stated that evidence for the oncolcgical effects of copper, even at high concentrations, is essentially 

nonexistent. With the exception of the references cited, there 

appear to be no definitive reports of copper as a causative agent 

in the development of cancer. There is much more evidence that a 

deficiency of copper will have adverse effects both in animals and 

in humans due to .Its ewen,tial role in the functioning of many enzyme systems. 

c-41 
CRITERION FORMULATION 

Existing Guidelines and Standards 

Far more attention has been given to the problems of copper 

deficiency than to the problems of excess copper in the environment. The 1 mg/l standard that has been established for copper 

levels in water for human consumption has been adopted more for 

organoleptic reasons rather than because of any evidence of toxic 

levels (Fed. Water Quality Admin., 1968). 

Cohen, et al. (1960) noted that various investigators have 

reported adverse taste of water containing 3 to 5 mg/l, 2 mg/l and 

1.5 mg/l of copper. The choice of 1 ppm as a level that was organoleptically satisfactory and below any values of health concern for 

humans was therefore considered reasonable. This study was used as 

a basis for the current drinking water standard. 

The U.S. Occupational Safety and Health Administration has 

adopted standards for exposure to airborne copoer at work. The 

time-weighted average for 8-hour daily exposure to copper dust is 

limited to 1 mg/m3 of air. The standard for copper fume was changed 

in 1975 to 0.2 mg/m3 (Gleason, 1968: Cohen, 1974). 

As indicated below, the Food and Nutrition Board of the National Academy of Sciences (1980) recommends a daily allowance of 

0.5 to 1.0 mg/day for infants, 1.0 to 2.0 mg/day for pre-schoolers, 

2.0 to 2.5 mg/day for older children, and 2.0 to 3.0 mg/day for 

teenagers and adults. 

Age. (yrs) RDA (mq/day) Age (yrs) RDA (mq/day) 

0.0-0.5 0.5-0.7 4- 6 1.5-2.0 

0.5-1.0 0.7-1.0 7-10 2.0-2.5 

l-3 1.0-1.5 ll-Adult 2.0-3.0 

C-42 
There are no standards for copper in medical practice such as 

the treatment of burns or dialysis or for parenteral feeding. 

Current Levels of Exposure 

As has been mentioned earlier, principal concern has been for 

conditions of copper deficiency rather than copper toxicity. It 

has been suggested earlier that copper intakes in food and water 

may ranqa from 6 to 8 mg per day, and that the percentage absorbed 

varies with the nutritional status. On the other hand, because of 

changes in food processing and, perhaps, because of better methods 

of analysis, copper intakes may not reach the 2 mg per day considered an adequate nutritional intake (Klevay, et al. 1977; Diem and 

Lentner, 1970; Robinson, et al. 1973; Schroeder, et al. 1966; WHO, 

1973; Cartwright and Wfntrobc, 1964a). 

The average concentration of copper in United States water 

systems is approximately 134 &l with a little over 1 percent bf 

the samples taken exceeding the drinking water standard of 1 mg/l 

(McCabe, et al. 1970). When the U.S. Public Health Service studied 

urban water supply systems, they found that only 11 of 969 systems 

had copper concentrations greater than 1 mq/l (W.S. HEM, 1970). 

In 1966, the National Air Sampling Network found airborne copper concentrations ranging from 0.01 to 0.257 ug/m3 in rural and in 

urban communities, respectively. Levels of copper as high as 1 to 

2 yg/m3 werm found near copper smelters, but this was not considered hazardous (Natl. Air Pollut. Control Admin., 1968; Schroeder, 

1970). 

c-43 
Special Groups at Risk 

Increased copper exposure, with associated health effects, has 

occasionally occurred in young children subjected to unusually high 

concentrations of copper in soft or treated water that has been 

held in copper pipes or stored in copper vessels. Discarding the 

first water coming from the tap can reduce this hazard. Similar 

problems have developed in vending machines with copper-containing 

conduits where acid materials in contact with the copper for periods of tine have dissolved copper into the vended liquids. 

Other groups that may be at risk are medical patients suffering from Wilson's disease and those patients who are being treated 

with copper-contaminated fluids in dialysis or by means of parenteral alimentation. These are medical instances in which the copper content of the materials used should be carefully controlled. 

There is also a reasonable likelihood that exposure to elevated levels of copper (ca. 1.0 ppm) from community drinking water 

may be a contributory factor in the precipitation of acute hemolysis in individuals with a glucose-6-phosphate dehydroqenase 

(G-6-PD) deficiency. Approximately 13 percent of the American 

black male population has a G-6-PD deficiency (Beutler, 1972). 

G-6-PD deficient humane were found to be.markedly more sensitive to 

several indicators of oxidant stress as measured by increases in 

methemoglobin. levels and decreases in the activity of red cell 

acetylcholineeteraea indicating that susceptibility to copperinduced oxidative stress is associated with the presence of low red 

cell G-6-PD activity (Calabrese and ?4oore, 1979; Calabrese, et al. 

1980). 

c-44 
A final group that may be subject to risk of copper toxicity 

consists of those people occupationally exposed to copper, e.g., 

industrial or farm workers. 

In reviewing the medical and biologic effects of environmental 

pollutants, the National Academy of Science (1977) pointed out, that 

use of livers from animals fed high levels of copper in the diet 

could produce a baby focd prcduct that was excessively high in copper. The Committee also raised the question of exposure to copper 

from intrauterine contraceptive devices (IlJDs), but subsequent reports have failed to demonstrate any abnormal accumulation of copper because of the use of these devices. 

Basis and Derivation of Criterion 

Copper is an essential dietary element for humane and animals. 

A level of 2 mg per day will maintain adults in balance (Adelstein, 

et al. 1956) and has been considered adequate, although because of 

interactions with other dietary constituents that limit absorption 

and utilization, a requirement level must be considered in conjunction with such constituents as zinc, iron, and ascorbic acid. The 

minimum level meeting requirements for copper intake in intravenous 

feeding is 22 vg copper/kg body weight (Vilter, et al. 1974). 

The short biological half-life of copper and the homeostasis 

that exists in humane prevents copper from accumulating, even with 

dietary intakes considerably in excess of 2 mg per day. In the 

opinion of many investigators, there is much more likelihood of a 

copper deficiency occurring than of a toxicity developing with current dietary and environmental situations. 

c-45 
Although acute and chronic levels Of intake may occur, there 

are no data that adequately define these Levels. It has been suggested that intakes above 15 mg of copper per day may produce observable effects, but if zinc and iron intakes are also increased, 

much higher levels may be consumed without adverse reactions. The 

data for acute toxicity are even more uncertain, since practically 

all human information stems from cases of attempted suicide. 

The available literature leads to the conclusion that copper 

does not produce teratogenic, mutagenic, or carcinogenic effects. 

The limited information available indicates that where such action 

has occurred, e.g., with mixtures of copper sulfate and lime, arsenic, or enediols, the copper should be considered as interacting 

with the other materials and not as the active material. 

The current drinking water standard of 1 mg/l is considered to 

be below any minimum hazard level, even for special groups at risk 

such as very young children, and therefore it is reasonable that 

this level be maintained as a water quality criterion. 

Since the current standard and hence the water quality criterion of 1.0 mg/l are based on organoleptic effects (U.S. LlEW, 1970) 

and are not toxicological assessments, the consumption of fish and 

shellfish is not considered as a route of exposure.
