Screening Quick Reference TablesThese tables were developed for screening purposes only: they do not represent official NOAA policy and do not constitute criteria or clean-up levels.All attempts have been made to ensure accuracy; however, NOAA isnot liable for errors. Values are subject to changes as new data become available.This set of NOAA Screening Quick Reference Tables, or SQuiRTs, presentsscreening concentrations for inorganic and organic contaminants in variousenvironmental media. Additional reference material, such as guidelines forsample preservation, are also included.NOAA identifies potential impacts to coastal resources and habitats likely to beaffected by hazardous wastes. To screen for substances which may threatennatural resources of concern to NOAA, environmental concentrations arecompared to these screening levels. These tables are intended for preliminaryscreening purposes only: they do notrepresent official NOAA policy and do notconstitute criteria or clean-up levels. NOAA does not endorse their use for anyother purposes. Screening levels are reported with the number of significantfigures they were originally reported with.In this new version, column headingslink to OR&R’s web site wherebriefdescriptions of the benchmark may be found. However, detailed guidance on therecommended application of various screening guidelines is provided in theoriginal sources (listed in each SQuiRTsection, with web links for many). Usersof the SQuiRT cards are strongly encouraged to review supportingdocumentation to determine appropriateness for their specific use.The SQuiRT card set has been re-organized from earlier versions toaccommodate expansion. Benchmarks from numerous new sources have beenincorporated, and the list of analytes vastly increased. The SQuiRT cardspresent benchmarks representing differentdegrees of protectiveness. Multiplebenchmarks are also provided in many cases: the user is advised to review thederivation of any particular benchmark before selecting a specific value.Information is still presented in sections, withnew sectionsappearing in thisexpanded version:• Inorganics in Sediment • Inorganics in Soil(freshwater and marine)• Inorganics in Water • Organics in Sediment(groundwater and surface water)• Organics in Water and Soil•PCB Composition•Toxic Equivalency Factors• Composition by Carbon Range• Guidelines for Sample Collection & Storage• Analytical Methods for Inorganics •Analytical Methods for OrganicsFootnotes within each SQuiRT section which appear at the bottom of the pageare only to aid in deciphering the nature of specific entries. Due to spaceconstraints, notations which relate to the source for individual values areexplained at the end of the section. Organic chemicals are now listedalphabetically, without categorization.A few synonyms are provided, but CASnumbers are also presented to aid in identifying and finding specific analytes.Except as noted, all concentrations in the SQuiRT cards are in parts per billion.For surface water samples, because releases from hazardous waste sites areoften continuous and long-term, concentrations are most often compareddirectly with chronic benchmarks, whenavailable. Groundwater concentrationsare also screened against chronic benchmarks. However, suitable site-specificdilution factors should be applied to allow for dilution upon migration anddischarge of groundwater to surface water. The SQuiRT cards present U.S.Environmental Protection Agency (EPA) Maximum Contaminant Levels (MCLs),applicable to drinking water sources and secondary MCLs applicable togroundwater, supplemented by values from Canada and the United NationsWorld Health Organization.Preference for surface water and groundwater benchmarks is given to U.S. EPAAmbient Water Quality Criteria (AWQC).This is generally followed by Tier IISecondary Acute Values (SAVs) or available standards and guidelines fromother regulatory agencies. Tier II SAVs are derived using a similar approach toAWQC, but do not have sufficient supporting data for full criteria calculation.Lowest Observable Effect Levels (LOELs)were originally published by EPA withAWQC. Around 2000, EPA stopped publishingthese values, however, LOELsare reproduced here when no other benchmark is available, because in manyinstances, they formed the basis for state standards.For many trace elements, AWQC are nowexpressed in terms of the “dissolved”fraction, which is essentially defined operationally as a filtered fraction. Likewise,the toxicity of many trace elements is related to the water hardness, and thevalues presented are for a default hardness of 100 mg/L CaCO3. Equations areprovided in the SQuiRT cards to calculate the exact criteria for a givenhardness, or, to convert from unfiltered,total concentrations to “dissolved”fractions.Screening Quick Reference Table for Inorganics in SedimentThese tables were developed for screening purposes only: they do not represent official NOAA policy and do not constitute criteria or clean-up levels.All attempts have been made toe subject to changes as new# - Based on SLC approach using sensitive species HC5%; ES&T 2005 39(14):5148-5156.* - Based upon EQp approach using current AWQC CCC^ - Based on SLC approach to derive LEL and SEL; Env’al Monitor & Ass’ment 2005 110:71-85+ - Carried over from Open Waterdisposal Guidelines; treated asif LEL for management decisions.Bioassay endpoints: M – Microtox; B – Bivalve;E – Echinoderm larvae; O – Oyster larvae;A – Amphipod; N – Neanthes; L –Larval bioassay; plus,I– Infaunal community impactsSources1 – Buchman, M. 1999.

There are 209 distinct congener structures possible, of which about 140 to 150 have been detected at significant levels incommercial PCBs.Congener distributions in environmental samples roughly resemble those of the parent commercial mixtures, but are often modified due to evaporation, water extraction, microbial oxidation or dechlorination,photochemicaldechlorination or differential biological uptake and metabolism. Compositional modification from original Aroclor patterns increases in biotic samples with trophic level. Still, it is often useful or necessary to attempt distinguishing theparent mixture released. The following information is presented to provide assistance with initial, preliminary evaluation of Aroclor.Aroclor assignment should be conducted only by qualified chemists.Total PCBs can be characterized by two primary methods – the sum of congeners, or, the sum of estimates of individual Aroclor concentrations. In lower trophic level samples, these two methods provide approximately equalestimates of total PCBs. At higher trophic levels, analyses of samples tend to overestimate total PCBs by as much as 2-fold using the sum of Aroclor method, due to an overestimation of Aroclor 1254.

# It has been well established that 2,3,7,8

- tetrachlorodibenzo

- p

- dioxin (TCDD), and other

chlorinated dioxins, furans, and even PCBs with a similar planar chemical structures

are capable of inducing similar toxicity, such as carcinogenicity. Since these

compounds generally are observed in mixtures, it is desirable to be able to express the

cumulative, overall toxicity of the mixture. However, since each of these congeners

does not exhibit the same degree, or potency, of toxicity, some manipulations of raw

concentrations are required to express total toxicity.

A number of systems have been developed to express the total, overall toxicity from

mixtures of these chemicals. Most commonly, the potency of each congener is

weighted relative to a standard, generally the most potent congener. For dioxins and

furans, 2,3,7,8

- TCDD is the common standard which is given a reference value of one.

The weighting, or potency factor, is called a Toxic Equivalency Facto r (TEF). When

cumulative results are reported, the absolute concentration of each congener is

multiplied by its corresponding TEF to derive a TCDD

- equivalency. These values are

then summed together to give a total Toxic Equivalency Quotient, or TEQ.

The TEQ scheme refers **only** to adverse effects (e.g., cancer) following interactions

with certain cellular enzyme systems (the Ah receptors). Other toxic effects of dioxins

and dioxin

- like compounds are not quantified by this method. Because they involve

potency to specific enzyme systems, TEF values vary for different animal species.

There are two main schemes:

The two most common systems for determining TEQs are:

1) I- TEF and I

- TEQ: The older International Toxic Equivalent (I

- TEQ) scheme by the

North Atlantic Treaty Organization (NATO) initially set up in 1989 and later

extended and updated.

2) WHO

- TEF and WHO

- TEQ (also referred to as TEF or TEQ): More recently, the

World Health Organization ( WH O ) suggested modified Toxic Equivalency Factor

(TEF) values for human risk assessment.

ITEQs are most common in North America, while Asia and Europe tend to use WHO

TEQs. On average, the result of TEQ

- calculations is about 10% higher when I

- TEFs

are used compared to when WHO

- TEFs are used.

Potency in fish reflects mainly rainbow trout: potency for birds is mainly derived from

chickens.

AA determinations are normally completed as single element analyses. ICP and Flame AA havecomparable detection limits (within a factor of 4), but ICP-MS (6020A) can drastically improve the detection limits (e.g., an order of magnitude lower). Furnace AA generally exhibits lower detection limits than ICP or Flame-AA, andoffers more control over unwanted matrix components.

For screening, trace element levels maybe compared to the geometric mean (and range) observed in natural soils in theU.S. Further comparisons to regional values is encouraged.Promulgated criteria or standards forsediments or soils are generally notavailable in the U.S. For screening purposes, contaminant levels in solids(sediment or soil) may be compared to benchmarks representative of differentcharacterizations of ecological risk. They shouldnotbe applied without areasonable understanding of their development, their performance, and theirlimitations.The NOAA SQuiRTs include multiple sediment screening values to help portraya spectrum of concentrations which have been associated with variousprobabilities of adverse biological effects. This spectrum ranges frompresumably nearly non-toxic to toxic levels. For instance, if all analytes screenbelow lower-threshold values (for example, TELs), this suggests, with a highdegree of confidence, that a sample withthese levels of contaminants has a lowprobability of being toxic, as tested through standard bioassays. Conversely,exceeding lower thresholds doesnotnecessarily predict toxicity. Comparison tohigher toxicity thresholds (for example, PELs) identifies compounds which aremore probably present at elevated, toxic levels.Sources of benchmarks for sediment were chosen primarily on the basis ofrepresenting a fairly unique approach for their derivation. A major exception isthe “Consensus TEC/PEC” values: these values are simply averages of otherexisting benchmarks (mostly those appearing in the SQuiRT cards). Theconsensus TEC/PECs are provided here merely as a service.For soil- and sediment-associated contaminants, dry weight concentrations arescreened directly against published benchmarks. Some benchmarks areavailable only on a Total Organic Carbon (TOC) normalized basis, and arefootnoted as such. Separate values are provided for either freshwater andestuarine or marine sediments.For freshwater sediments, the UpperEffects Threshold (UET) was derived byNOAA as the lowest AET from a compilation of endpoint analogous to themarine AET endpoints. The UETs for organic contaminants are generally listedfor a sediment containing 1% TOC.This version of the SQuiRT cards adds a section on the composition of PCBs.A characterization of Aroclors by their degree of chlorination and congenerpatterns may aid inpreliminaryexploration of source type. Definitive Aroclorassignment should only be conducted by a qualified chemist.To express cumulative toxicity from mixtures of dioxins and furans, ToxicEquivalency Factors are included in this version of the SQuiRT cards. Absoluteconcentrations can be multiplied by the TEF potency factors and the productsthen summed to derive total toxicity.Every effort has been made to ensure accuracy in these SQuiRT cards.However, NOAA is not liable for errors inoriginal sources or revision of values.These screening values are subject tochange as new data become available.The SQuiRT cards may be freely reproduced and distributed, if they aredistributed in their entirety,without modification, and properly credited to NOAA.The SQuiRT cards should be cited as:“Buchman, M.
