iiFOREWORD 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 FR43660), and October 1, 1979 (44 FR56628). 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 ERC2120 (D.D.C. 1976), modified, 12 ERC1833 (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 adifferent 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 maywant 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.

vCRITERIA DOCUMENT 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 1mg/l. It should be recognized that organoleptic data as a basis for establishing awater quality criteria have limitations and have no demonstrated relationship to potential adverse human health effects.

viCopper is asoft heavy metal, atomic number 29, with an atomic weight of

63.54, amelting point of 1,083°C, a boiling point of 2,595°C, and adensity 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-1Zirino and Yamamoto (1972) developed amodel 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 pH7to less than 0.1 percent at pH8.6. 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.

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 arange 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

ion in free and complex forms, is aminor 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-1The 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, awater 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

total recoverable cooper concentrations 

### in the tests should be nearly equivalent, andthe results are used interchangeably. Because amajority of the reported 

### test results (Tables 1 and 2j nave been conducted with oligotrophic 

### raters having relatively low complexing capacities, 

### the criteria derived 

### herein maybe at or below ambient total copper concentrations in somesurface waters of the United States. Season- ally and locally, toxicity in these waters maybemitigated by the presence of naturally occurring chelating, complexing, and precipitating agents. In addition, removal from

### 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 

### amuchbetter fit with the available acute toxicity data, because the upper limit is higher at high hardness to reflect calcium antagonism and

### carbonate complexation. Somedata onthe relationship of toxicfty to other factors, i.e., temperature, alkalinity, size of organism, and total organic carbon, are available for alimited number of soecies andwfll 

### bedfscussed later. The follouing data on the effects of copper on aquatic biota (Tables I through 6) 

### havebeen summarized front the literature from 

### 1950to 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-3effects are of nrinor impot:ance relative to toxicity of copper to fish and

jnvertebrate species. 11: concentrations are reoorted ascooper, not asthe compound. EFFECTS &cute Toxicity Acute toxicity tests with czpper have been conducted on 18 invertebrate and27fish species (Table l), with approximately 

### 175acutevalues 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 beequivalent 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 moreresistant to copper than juveniles. This factor is obviously asource 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 afew 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 avariety 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 2to 3mg/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 acorrelation of acute toxicity and hardness. Theslope of the regression equations ranged from 0.67 for chinook salmon to 1.34 for Daphnia magna with an arlthrnetlc meanof 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 andconfirm 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-5aquatic animals. The mean slope (0.94) was fitted throl;gh the geomevic

rrean toxicity value 

### andhardness 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 ameasure of rel'ative soecies sensitivlty to copper (Table 3). Daphnia pulicaria wasfound to bethe most sensitive species. Two other daphnid soecies and the scud Gammaruspseudolimnaeus 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 3to 11 times more resistant. Bluegi 11s and other centrarchids are approximately 

### 10to100times more

### resistant thansalmonids. Afreshwater Final Acute Intercept of 0.29 ug/l was obtained for copper using the species mean acute intercepts listed in Table 3and 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 5gikg. 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 

### was560 ug/l for the adult ?acific oyster,

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

### according tothe 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 anacute value of 31 Ug,'\ for Acartia tonsa (Sosnowski and Gentile, 1978), and the least sensitive of ali animals tested, with anacute 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 betwice assensitive to copper asthe 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 summerflounder 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 1because embryos of these species apparently are 

### not resistant to copper and because other 

### acutevalues 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 10g/kg than at 

### 30g/kg (Birdsong aodAvavit 1971). Other species of saltwater fish were tested for sensitivity to 

### copper, but the experimental conditions were not suitable for inclu8-7sion in either 

### theacuteor chronic tables; consequently, these data ;Irere

placed in Table 6. 

### Also, a

### numberof scientists exposed anadromous species such as Atlantic 

### andcoho salmon to copper in freshwater. These 

### datawere utilized in deriving the freshwater criterion, but not the saltwater criterion. ASaltwater Final Acute Value of 22.9 ug/l wasobtained 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. Thechronic values range from alowof 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 arange of 6.1 to 29.0 ug/l. Aseries of tests wfth Oaphnfa magna in 

### a hard pond water (Table 6) wfth unmeasured copper concentrations resulted in chronic values of about 49ug/l. Thedata available concerning the effect of hardness onthe chronic toxicfty of 

### COQQWis somewhat nebulous. The total range of chronic values is 3.9 to 60.4 ug/l (Table 2). which is 

### muchless 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 andwaters used in the two kfnds of tests, but it mayalso indicate that hardness affects chronic tox8-8iCity 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 amedium 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 donot showany consistent relationship. Thefour chronic tests with the fathead minnow also showed aconsistent but small effect of hardness on chronic toxicity. The slope of 0.26 is not statistically significant and is 

### muchless than the acute mean slope of 0.94. A chronic value (Table 6) from atest conducted with the fathead minnow in a hard stream water contaminated with sewage effluent (8rungs, et al. 1976) wasmore 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. Onthe other hand, afactor 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 seemsto increase with hardness.



### B-9The 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 avariety 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 2using the calculatjon 

### procedures described in the Guidelines, is 5.6 ug/l. The only chronic value reported (Table 2) for asaltwater species was that for the mysid shrimp, Mysidoosis bahia (U.S. EPA, 1980). The chronic toxicity of copper to this saltwater invertebrate wasdetermined in 

### aflowthrough 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 27.0 ug/l, 38.5 26.3 ug/l, 77.4 f, 7.4 ugll, 140.2 2 11.8 ugll) for 46days at 20'C and 30 g/kg salinjty. The biological responses examined included time of appearance of first brood, 

### the number of spawns, meanbrood size, and growth. The appearance of embryos in the brood sac was delayed for 6 and 8days at 77 ug/l and 140ugil, respectively. The number of spawns recorded at 77~g/l wassignificantly (p <0.05) fewer than at 38.5 ug/l. The number of 

### spawnsat 24 and 38 ug/l wasnot signiffcantly different from the control. Brood size was sfgnificantly (p <0.05) reduced at 77ugll but not at lower=concentratlons, and no effects on growth were detected at any of 

### the coopw concentrations. Based 

### uponreproductive data, adverse effects were observed at 38 ugll, but not at 77ug/l, resulting in achronic 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),

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. NoFinal Plant Value can beobtained because none of the plant values were based onmeasured concentrations. For saltwater algae the concentrations cent reduction in photosynthesis or growth species of macro-algae and eight species ofof copper which cause a50 perare tabulated in Table 4for one micro-algae.

### 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.

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 aseries of measurements witn algae by Riley and Roth (1571) the highest reported concentration factor was617 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 a140day continuous exposure to 50ug/l. Even though the tissue of the oyster becamebluish-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

maximum permissible tissue concentration exists, neither a asaltwater Final Residue Value can becalculated. Miscellaneous The results of manyadditional tests of the effects of copper onfreshwater aquatic organisms are listed in Table 6. Many of these are acute tests with non-standard durations for the organisms used. Manyof the other acute tests-in Table 6were 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 

### Pulicar3-12ia and fathead minnow in waters with concentrations of T.O.C. ranging upto

34mgll. 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 aturbid pond water. Until chemical measurements which correlate well vrith the toxfcity 0.fcopper in awide variety of waters 

### are identified and widely used, results of tests in unusual dilution waters, such asthose in Table 6, will not bevery 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 dueto chronic exposure at very low concentrations of copper. Sumnary Acute toxicity data are available for 45 species of freshwater animals. Theapproximatqly 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 andtotal organic carbon. Therange of acute values indicates that someof the more resistant species could survive in copper concentrations over 100 times that which would

### bereadily lethal to the more sensitive species. Amongthe more sensitive

species are daphnids, scuds, midges, and snails which form the major focdwebsfor 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

### 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 awide range of 

### plant species, with results

Control Fed. 41: 280.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-1from 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. 1The 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.

## that if hot water from the

## 134ug/l [U.S. 

## Department of Health, Education andWelfare (U.S. HEW), 19701. The highest concentration reported was

## 8,350 ug/l; alittle over 1percent of the samples exceeded the 

## drinking water standard of 1mg/l. The 

## 1mg/l copper 

## standard wasestablished not because of toxicosis but because of the taste which

that the concentration of

## This is evident from studies inEngland, NewZealand, andthe United States. Lowerestimates havebeen 

## made for certain Dutch and poorer Scottish diets, while Indian adults consuming rice andwheat diets have been shownto ingest from 4.5 to 5.8 mgof copper per day (Schroeder, et al.

Klevay, onthe other hand, hassuggested onthe basis of recent food analyses that the copper content maybeless than earlier analyses indicated andhascautioned that United States diets maynot beadequdte to provide 2mgof copper per day (Klevay, 1977; Klebay, et al. 1977).

## Muchof the

## e.g., the iris andthe choroid of the eye

## ,which maycontain asmuchas100~g/gm (Bownessand Morton, 1952; Bowness, et al. 1952). Estimates of the total amount of copper in a70kgmanhave ranged from 70to 120mg. Approximately one-third

## 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

### Copper levels

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 maybeuseful 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 

## meanconcentration of 

## copper in hair

## whohadnot. 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 Sug/lOO ml to 130 pg/lOO ml. In practically all species, copper deficiency is first 

## manifested by

## aslow depletion of body copper stores, including the blood 

## plasma, eventually resulting in

## anemia identical to that 

## caused by iron deficiency (Cartwright, et al. 1956). Both the plasma

## of the 

## copper in the blood

## Ceruloplasmin represents the predominant portion of cooper in the serum pool. There 

## appears to be little or no interchange between

C-26

### copper/100 ml of blood). White blood cells contain asmall 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

## appear to be

## acorrelation between maternal and fetal copper 

## Concentrations. At

## contains about 4mg/kg ascompared to approximately 1.4 mg/kg 

## in the 70

## kgman(Widdowson andDickerson, 1964). The liver of the newborn

## manonaper grambasis (Bruckmann andZondek, 1939; 

## Nusbaumand Zettner, 1973; 

## Widdowson, et al. 1951). The

## The liver copper content of the fetus is several times higher than maternal liver copper (Seeling, et al. 1977).

C-27

## Hetabolism

Thecopper 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). Some20mammalian copPer proteins have been isolated, but at least three are identical andothers havemorethan onename. Most of this information hascomefrom animal studies, and its applicability to 

## humans is uncertain. Evans (1973) andothers have re

## viewed this subject (Mannand 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 dueto the increased synthesis of ceruloplasmin (Henkin, et al. 1972; Markowitz, et al. 

## 1955; Scheinberg, et al. 1954). Thesource of this copper appears to be the maternal liver. The increase in maternal plasma copper levels appears to beassooiated with estrogen, since either sex receiving estrogen 

## showsanincrease in copper 

## level of the plasma (Elsner andHornykiewicz, 1954: Gault, et 

## al. 1966: Humoller, et al. 1960: RussandRaymunt, 1956). The use 

## of oral contraceptives causes amarked increase in serumcopper lavels that maybegreater 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).

### There are 

### two inherited 

## diseases that represent abnormal cop

## per metabolism, Menkes' disease andWilson’s 

## disease. Yenkes' disease is aprogressive brain disease caused by an inherited sex

## linked 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 beadiminished ability 

## to transfer copper across the absorptive cells of the 

## intcstinalmucosa (Danks, et al. 1972, 1973). Thegeneral symptoms 

## of the disease are similar to those observed in animals suffering 

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

## prospects for moreeffective therapeutic measures as a result of 

## early diagnosis 

## appear to belimited. 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 acopper 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 andGitlin, 1952), decreased in

## testinal 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 ofWflronls disease, it 

## canassure anormal life expectancy, especially when accompanied by 

## a low-copper diet (Deias, et 31. 1971: Sternlieb andScheinberq, 1964, 1968; WaSshe, 1956). Other abnormalities of copper 

## metabolism are primarily associated with low levels of 

## copper. Ayoocupremia, which is defined as



## c-2980 'Jg or 

### less of copper/100 ml (Cartwright and Wintrobe, 1964a),

usually 

### refers to 

## alow ceruloplasmin level. In most 

## cases it 

## is probably due to 

## adietary deficiency of copper or to 

## afailure to synthesize the apoenzyme of ceruloplasmin 

## (Kleinbaum, 1963). HYPOcupremia 

## can also result from malabsorption that occurs during 

## a small bowel 

## disease (Sternlieb andJanowitz, 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 

## serumcopper levels occur in psoriasis (Kekki, et al. 1966; 

## Molokhia and Portnoy, 1970). It is well recognized that copper is 

## necessary for the utili

## zation of iron. 

## Muchof this work 

## hasbeendone in 

## animals, andthe 

## subject is well covered byUnderwood (1977). It appears that ceruloplasmin is essential for the movementof iron from cells to plasma (Osaki, et 

## al. 1966). Reticulocytes from copper-deficient animalscanneither pick upiron from transferrin normally nor synthesize heme from 

## ferric iron andprotoporphyrin at the 

## normal rate 

## (Williams, et al. 1973). The 

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

## sulfate, andmolybdenum, maybealmost as important a3 the actual level 

## of copper in the diet 

## in influencing the metabolic response of mammalian species (Smith

This appears to be associated with a biochemical lesion, the reduced activity of lysyl oxidase, acopper-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 

## andits ratio to zinc asafactor in the level of cholesterol

## mucosae (Gollan andDeller, 1973). It should benoted that someof the excreted copper is re

## absorbed 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 bythis route is fragmentary. Cartwright andWintrobe (1964a) suqqest 

## that 0.5 to 1.2 mqper 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). Somecopper 

## (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 1mq

## 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 andaverage 18 ug/day (Cartwright 

## andWintrobe, 1964a; Zak, 1958). It 

### is possible, of courser that copper maybe reabsorbed from the kidney tubules (Davidson, et al. 1974). 

## C-32

### Studies in New

## Zealand conducted onyoung womenwith acopper

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 aconsiderable 

## amount of copper maybe 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 byway of the menstrual flow, but an average value 

### of 0.11 f 0.07 mgper period seems reasonable (Ohlson and 

## Daum, 1935; 

## Leverton and

## Binkley, 1944). Sternlieb, et al. 

### (1973) note that 0.5 to 1.0 mgof copper is catabolized daily by 

### the adult liver, and about 

### 30 mgof 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 

### maynot be 

### readily 

## available for reabsorption because it is 

## bound to protein: the copper found in the feces seems to come from various secretions, aswell as the copper that is not absorbed from food (Gollan and Deller, 1973). In summary it may be 

### said that most copper is excreted byway 

## of the Uliary system 

## with additional amounts in sweat, urine, saliva, gastric 

### and intestinal mucosae, and menstrual discharge. Examination of the pharmokinetic data points upthe 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, andChronic Toxicity Copper toxicity produces ametallic taste in the mouth, nau

## sea, vomiting, epigastric pain, diarrhea, 

## and depending on the severity, jaundice, 

## hemolysis, hemoglobinuria, hematuria, and oli

## guria. Thestool and saliva 

### mayappear green or blue. In severe 

## cases anuria, hypotension, andcomacanoccur. Toxic levels of copper ingested are promptly absorbed from the upper gut, 

## andthe 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, aswhenapplied to burns, because 

## of dialysis 

## procedures, or because 

### of exchange transfusions. 

## Thehemolysis is 

## dueto the sudden release of copper into 

## the blood 

## stream from the liver that has been 

## damaged by

## anincreasing load 

## of copper andis unable to utilize the 

## copper in the 

## synthesis of ceruloplasmin, which in turn canbeexcreted by 

## wayof 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 andGanguly (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 anadult manis greater than 15mgper dose. The

## vomiting anddiarrhea induced by ingesting small quanti

## c-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 mostof the information about acute copper toxicity in humans has comefrom 

## 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 doesoccur in manwhenseveral gramsof copper sulfate are eaten with acidic food or beverages 

## suchasvinegah carbonated beverages, or citrus juices 

## (Walsh, et al. 1977). Somecases of acute poisoning haveoccurred whentablets 

### containing 

## copper sulfate were given to children (Forbes, 1947). Whencarbonated water remains in copper check valves ordrinkdispensing machines overnight, the copper content of the first 

## drink of the 

## daymaybeincreased enough to cause 

## ametallic 

## taste, nausear vomiting, epigastric burning, and diarrhea (Hooper and Adams, 1958). Drinks that are stored in copper-lined cocktail 

## shakers orvessels canhavethe sameeffect (Pennsylvania Morbidity andMortality Weekly Reports, 1975: McMullen, 1971). Salmon and Wright (1971) have reported the possibility of chronic comr poisoning asa-result of water moving through copper 

## pipes. They-document acase inwhich afamily movedinto ahouse in North London with ahot water system entirely composedof copper. Thewater wasstored in a40-gallon copper tank which 

## reached a temperature of 93OCat night. The 

## family used hot water for 

## all

c-35

### cooking and beverages. After two rr,ontfis, the electric kettle was

coated inside with athick green film 

## of the copper complex. The child in the family 

## wasadmitted to the 

## hospital after five weeks 

### of behavior 

## change, diarrhea, and progressive marasmus. Whenit 

## was first 

## seen, the clinical picture wasthat of "pink" disease with prostration, misery, 

## red extremities, hypotonia, photophobia, andperipheral edema. The liver 

## waspalpable 2cmbelow the costal margin. 

## Theserum copper level was286 pg/lOO ml, compared to a normal range of 164270ug/lOO ml. 

## Analysis of water in the home 

## found 350pg/l of copper in 

## the cold water and790ug/l of copper in the hot 

## water. Cold andhot water levels in the 

## hospital were40 and300ug/l, respectively, and in North London the values were 80 and 160ug/l. Walker-Smith 

## andBlomfield (1973) 

## treated the 

## male infant de

## scribed in the preceeding paragraph, who

## had received high levels of copper from contaminated water over aperiod of three months, with d-penicillamine andprednisolone. Theinfant madeaslow recovery. Themethod of EdenandGreen (1940) wasusedto determine copper levels. It is possible that 

## the infant wasexhibiting Wil

## son's disease andresponded to the appropriate treatment. Edenand Green 

## (1940) reported on a 

### male 

## infant 'whoreceived high levels 

## of copper frosncontaminated water ingested over aperiod of three months. The result was 

## chronic copper poisoning. Treated 

## with d-penicilliamine and prednisolone, 

## the infant madea slow recovery. In 

## general, however, the problems associated with high levels 

## of copper in drinking water are more 

## or Lesscontrolled because of

C-36

### (1) taste (since high levels of copper in water produce ametallic

taste), and (2) cosmetic considerations (since water with high copper content develops a

## surface scumdue to the 

## formation of insoluble copper 

## compounds). Chronic 

## toxicity has been studied in animals, andthere appears to be

## awide 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. 

## Thesesigns of copper toxicosis in swine 

## canbeelim

## inated by 

## including an additional 150 pgof zinc and iron/g in diets containing up to 450 ug 

## of copper/g; the addition of even more zinc 

## and iron, 500to 750pg/g, will overcome the effects of 750ugof 

## 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). 

## Somequestion exists as to whether hemosiderosis in 

## manis 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 aperiod of nine months to one

## year (Fontenot, et al. 

### 1972). Cattle 

### are muchmore resistant to copper in the diet; 2gof 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 aratio of l:l,OOO lowered 

### the most 

## active concentration of the triose reductone to 1mMfrom 

## 2.5 to 5ref. Another enediol reductone, 

## asborbic acid, had no detectable mutagenic action by 

### itself, but a

### freshly mixed 

## solution of 5mMof 

## ascorbic acid and 1or 5 UM

### of cupric copper had aneffective mutagenic action. Ascorbyl-3-phosphate had nomutagenic function even in the presence 

## of cupric copper. The investigators suggested that it 

## wasthe 

## 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

## ateratoqenic effect in either animals or humans. Mutagenicity Nodata were found to suggest that copper itself has a muta

### genic effect in either animals or humans: however, one report exists suggesting that copper may increase the mutagenic activity of 

## other compounds (see Synergism 

## andAntagonism section). Carcinoqeniclty There is very little 

## evidence in the literature to suggest 

## that copper hasacarcinogenic effect in either animals or humans. Pimental 

## andMarques (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 andmalignant tumors in the lung (Pimental and Menezes, 

## 1975; Villar, 1974). 

## Because of the 

## route of expoaure, quantitative estimates are, at best, 

### speculative. 

## It hasbeennoted earlier that the conditions in industry that would produce excessive concentrations of copper 

## as adust or a mist with 

## particle sizes that would result in toxic effects if the 

## copper were absorbed, 

### are apparently quite rare. Some investigators 

## havesuggested 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 

## andthe 

## tumor tissue 

### is likely to increase, although this is not 

## always the case (Pedrero 

## andKozelka, 1951; Dick, 1953; Kline, et 

## al. 1971: 

## Wahal, et al. 1965). Kowever, when an increase occurs, 

### it appears to be 

## a result of 

## aninflammatory response or stress rather than anydirect causative relationship. Polish 

## workers (Legutko, 

## 1977) havesuggested that the copper level of the serum is a particularly sensitive 

## indicator 

## of the clinical condition 

## andeffectiveness of treatment of lymphoblastic 

### leukemia in children, but 

## again noparticular relationship to 

## the development of the leukemia 

## is indicated. Russian scientists (Bezruchko, 1976) 

## have also studied the 

### copper 

## andceruloplasmin in 

## patients with cancer andnoted that the levels 

## of both ceruloplasmin 

## and

## copperwere increased in 

## metastatic 

## cancer of the 

## mammarygland, in skin 

## melanoma, and in ovarian cancer. The serum 

## levels of ceruloplasmin increased 27, 20, and 44 

## percent, respectively, for those tumors, andthe copper increased by41, 35, and51percent, respectively, 

## for those sametumors as compared with 

## normal tissue. Again, nocorrelation wasfound be

### tween the tumor 

## and

## copper asacausative agent. Workers in 

## HongKong (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 andthat this 

## is paralleled by

## adecrease inzinc content.

c-40

## In 3ummaryl 

### it must 

## bestated that evidence for the oncolcgi

## cal effects of copper, evenat high concentrations, is essentially nonexistent. With the exception of the references cited, there 

## appear to be 

## nodefinitive reports of copper asacausative agent in the development of cancer. There is muchmore evidence 

## that a deficiency of copper will haveadverse effects 

## both in animals and in humansdueto .Its ewen,tial 

## role in 

## the functioning of manyenzymesystems.

c-41

### CRITERION FORMULATION

Existing Guidelines 

## andStandards Far more 

## attention has been given to the problems of copper deficiency 

## than to 

## the problems of excess copper in the 

## environment. The 

## 1mg/l standard that has been established for copper levels in water for humanconsumption 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 3to 5mg/l, 2mg/l 

## and 1.5 mg/l of copper. The

## choice of 1ppmasalevel that wasorganoleptically 

## satisfactory and below 

## anyvalues of health concern for humanswastherefore considered reasonable. This 

## study wasusedas abasis 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 

## 1mg/m3of air. Thestandard for 

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

## As indicated below, 

## the FoodandNutrition Board 

## of the National Academy

## of Sciences (1980) recommendsadaily 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 nostandards for copper in medical practice such as

the treatment of burns or dialysis or for parenteral feeding. Current Levels of Exposure Ashas 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 6to 8mgper 

## day, and that the percentage absorbed varies with the 

## nutritional status. Onthe other hand, because of 

## changes in 

## food processing and, perhaps, 

## because of better methods of analysis, 

## copper intakes may

## not reach the 2mgper 

## dayconsidered 

## anadequate nutritional intake (Klevay, et al. 1977; Diem 

### and 

## Lentner, 1970; Robinson, et 

## al. 1973; 

## Schroeder, et 

## al. 1966; WHO, 1973; Cartwright 

## andWfntrobc, 1964a). The average concentration of copper in United States water systems is approximately 134 &l with alittle 

## over 1percent bf the samples 

## taken exceeding the drinking water standard of 1mg/l (McCabe, et al. 1970). 

## Whenthe 

## U.S. Public Health Service studied urban water supply systems, they found 

## that only 11

## of 969 systems 

## had copper 

## concentrations greater than 1mq/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 ashigh as 

### 1to 2yg/m3 

## wermfound near copper smelters, 

## but this 

## wasnot 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 inyoungchildren 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 havedeveloped 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 maybeat risk are medical patients suffering fromWilson's disease 

## andthose patients who are 

### being 

## treated with copper-contaminated fluids in dialysis or bymeansof paren

## teral alimentation. These 

## are medical instances 

## in which the cop

## per content of 

## the materials used should 

## becarefully controlled. There is also a reasonable likelihood that exposure to elevated levels of copper (ca. 1.0 ppm) from 

## community drinking water maybeacontributory 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-PDdeficient humane

## werefound 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

### Afinal group that maybe subject to risk of copper toxicity

consists of those 

## people occupationally exposed to copper, e.g., industrial 

## or farm 

## workers. In reviewing the 

## medical andbiologic effects of environmental 

## pollutants, the National Academyof 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 wasexcessively 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 anyabnormal accumulation of copper because of the 

## useof these 

## devices. Basis andDerivation of Criterion Copper is anessential dietary element for humaneandanimals. 

## Alevel of 2mgper daywill maintain adults in balance (Adelstein, et al. 1956) 

## andhasbeenconsidered adequate, although because of interactions with other dietary constituents that limit absorption and 

## utilization, arequirement level mustbeconsidered in conjunction with such constituents aszinc, iron, andascorbic acid. The 

## minimumlevel meeting requirements for copper 

## intake in intravenous feeding is 22vgcopper/kg bodyweight (Vilter, et al. 1974). The 

## short biological half-life of copper and the 

## homeostasis that exists in humaneprevents copper from accumulating, 

## evenwith 

## dietary intakes considerably in excess of 2mg

## per day. In the 

## opinion of manyinvestigators, there is much more likelihood of a 

## copper deficiency occurring than of atoxicity developing with cur

## rent dietary andenvironmental situations.



## c-45

### Although acute 

### and chronic levels Of intake mayoccur, there

are 

## nodata that adequately define these Levels. It 

## has been suggested that 

## intakes above 

## 15mg

## of copper per day mayproduce observable effects, but if 

## zinc and iron intakes are also increased, 

## muchhigher levels maybeconsumedwithout 

## adverse reactions. The 

## data for acute toxicity are evenmoreuncertain, since practically all humaninformation stems 

## from cases of attempted suicide. Theavailable literature leads to the conclusion that copper does not produce teratogenic, mutagenic, or carcinogenic effects. The 

## limited information available indicates that where suchaction hasoccurred, e.g., with mixtures 

## of copper sulfate andlime, 

## arsenic, or enediols, the copper should beconsidered as interacting 

## with the other materials andnot asthe active material. The

## current drinking water standard of 1mg/l is considered to be 

## below anyminimumhazard level, even 

## for special groups at risk 

## such asvery young children, and therefore it is reasonable that this 

## level be 

## maintained asawater quality criterion. Since the 

## current standard andhence the water quality criterion 

## of 1.0 mg/l 

## are basedonorganoleptic effects (U.S. LlEW,1970) andare not toxicological assessments, the 

## consumption 

## of fish and shellfish 

## is not considered asaroute of 

## exposure.
