                                  FOREWORD

     Section 304(a)(l) of che Clean Wacer Ace of 1977 (P.L. 95-217) requires
Che Adminiscracor of che Environmencal Proceccion Agency co publish criceria
for wacer qaalicy accuracely reflecting che lacesc scientific knowledge on
che kind and excenc of all idencifiable effeccs on health and welfare which
may be expected from che presence of pollucancs in any body of wacer,
including ground wacer.  This document is a revision of proposed criceria
based upon a consideracion of coraraencs received from other Federal agencies,
State agencies, special inceresc groups, and individual scienciscs.  The
criceria concained in chis document replace any previously published EPA
aquacic life criceria.

     The certs "wacer qualicy criceria" is used in cwo seccions of the Clean
Wacer Ace, seccion 304(a)(l) and seccion 303(c)(2).  The cerm has a differenc
program impace in each seccion.   In seccion 304, the cerm represents a
non-regulatory, sciencific assessment of ecological effeccs.  The criteria
presenced in chis publicacion are such sciencific assessments.  Such wacer
qualicy criceria associated with specific stream uses when adopted as State
wacer qualicy scandards under seccion 303 become enforceable maximum
accepcable levels of a pollutant in ambient waters.  The wacer quality
criceria adopted in che Scace wacer qualicy standards could have the same
numerical limits as che criceria developed under seccion 304.  However, in
many situations States may wane  co adjust water quality criceria developed
under seccion 304 co reflecc local environmental conditions and human
exposure patterns before incorporation inco wacer quality standards.  It is
noc uncil their adopcion as pare of che Scace wacer qualicy scandards chac
che criceria become regulatory.

     Guidelines co assist che Scaces in che modification of criceria
presenced in chia document, in che development of wacer quality scandards,
and in ocher wacer-relaced programs of chis Agency, have been developed by
EPA.

Introduce ion*

     Mercury has long been recognized as one of the raosc coxic of che heavy

raecals, but only recently was ic identified as a serious poLLucanc in che

aquatic environment (National Research Council, 1978; National Research

Council Canada, 1979; Nriagu, 1979).  Elemental mercury is a heavy liquid ac

room temperature and was considered relatively inert, because ic was assumed

that ic would quickly settle to che bottom of a body of water and remain

there in an innocuous state.  However, elemental mercury is oxidized co

mercury(II) under natural conditions (Wood, 1974).  Furthermore, mercury(II),

whether discharged directly or produced from elemental mercury, can be

methylated by both aerobic and anaerobic bacteria (Akagi, 1979; Beijer and

Jernelov, 1979; Callahan, et al. 1979; Jernelov, 1971, 1972; Jernelov, et al.

197S; National Research Council, 1978; Summers and Silver, 1978; Thayer and

Brinckman, 1982; Wright and Hamilton, 1982).  Mercury(ll) can also be

methylated in the slime coat, liver, and intestines of fish (Jernelov, 1968;

Matsuraura, et al. 1975; Rudd, et al. 1980b), but raechylacion apparencly does

not occur in other tissues (Huckabee, ec al. 1978; Macida, ec al. 1971;

Pennacchioni, et al.  1976) or in plants (Czuba and Horcimer, 1980).  (The

term "mechylmercury"  is used herein to refer only co raonoraechylraercury, and

not to dimethylmercury or any other monoor^anoraercury sale or diorganomercury

compound.  Inorganic  mercury(II) will be referred co as "raercury(II)".)

     The importance of mechylation may be reduced by demechylacion (Bisogni,

1979; Ramamoorchy. et al. 1982).  Demechylacion mighc provide a feedback
*An understanding of the "Guidelines for Deriving Numerical National Water
Quality Criteria for che Proceccion of Aquacic Organisms and Their Uses"

mechanism that controls che concencracion of raethylmercury in sediraenc and in




wacer.  Jernelov, ec al. (1975) cited a case in which low levels of raethyl-




mercury in fish from a highly contaminated area coincided wich strong




methylmercury degrading activity in the sediment.  Demethylation also occurs




in fish (Burrows and Krenkel, 1973; de Freitas, et al. 1981; Gage, 1964;




Olson, ec al. 1978), probably as part of the depuration mechanism.




     Numerous factors such as alkalinity, ascorbic acid, chloride, dissolved




oxygen, hardness, organic complexing agents, pH, sediment, and temperature




probably affect the acute and chronic toxicity and bioaccuraulation of the




various forms of mercury (Amend, et al. 1969; Baker, et al. 1983; Feich, et




al. 1972; Hahne and Kroontje, 1973; Jernelov, 1980; Ramamoorthy and




Blumhagen, 1984; Ribeyre and Boudou, 1982; Rogers and Beamish, 1981, 1983;




Rudd, ec al. 1980a; Rudd and Turner, 1983a,b; Sharma, et al. 1982; Stokes, et




al. 1983; Tsai, et al. 1975; Wren and MacCriraraon, 1983; Wright and Hamilton,




1982).




     A variety of studies have been conducted on the effect of selenium on




the acute toxicity of mercury (e.g., Birge, et al. 1931; Bowers, et al. 1980;




Oe Filippis, 1979; Heisinger, 1981; Heisinger, et al. 1979; Klaverkarap, et




al., 1983a; Lawrence and Holoka, 1983; Sharma and Davis, 1980c) and on che




accumulation of mercury from food and water (e.g., Beijer and Jernelov, 1978;




Chang, et al. 1983; Heisinger, et al. 1979; Klaverkarnp, et al. 1983b; Rudd,




et al. 1980a; Sharma and Davis, 1980c; Speyer, 1980; Turner and Swick, 1983).




Available data do not, however, show that quantitative relationships are




consistent enough for a variety of aquatic species to enable relating water




quality criteria to any of these variables.




     Because of the variety of forms of inorganic and organic mercury and




lack of definitive information about their relative toxicities, no available




                                      2

-------
analytical measurement is known co be ideal for expressing aquacic Life




criteria for mercury.  Previous aquacic life criteria for mercury (U.S. EPA,




1980) were specified in terms of total recoverable mercury, which would




probably be measured as total mercury (U.S. EPA, 1983a),  but both of chese




measurements are probably coo rigorous in some situations.  Acid-soluble




mercury (operationally defined as the mercury chat passes through a 0.45 jra




membrane filter after the sample is acidified co pH • 1.5,co 2.0 wich nicric




acid) is probably che best measurement at the present for the following




reasons:




1.  This measurement is compatible with all available data concerning




    toxicity of mercury to, and bioaccumulation of mercury by, aquacic




    organisms.  No test results were rejected just because it was likely that




    they would have been substantially different if they  had been reported in




    terms of acid-soluble mercury.  For example, resulcs  reported in terms of




    dissolved mercury would not nave been used if the concentration of




    precipitated mercury was substantial.




2.  On samples of ambient water, measurement of acid-soluble mercury should




    measure all forms of mercury that are coxic co aquacic life or can be




    readily converced co toxic forms under natural conditions.  In addicion,




    this measurement should not measure several forms,  such as mercury chac




    is occluded in minerals, clays,  and sand or is scrongly sorbed co




    particulate matter, that are not toxic and are not  likely co become coxic




    under natural conditions.  Although this measurement  (and many ochers)




    will measure soluble, complexed forms  of mercury, such as che EDTA




    complex of mercury(ll), chac probably have low toxicicies co aquacic




    life,  concencracions of chese forms probably are negligible in mosc




    ambient water.



                                      3

-------
3.  Alchough water qualicy criteria apply co ambienc wacer, che measurement




    used co express criteria is Likely to be used co measure mercury in




    aqueous effluents.   Measurement of acid-soluble mercury should be




    applicable co effluencs because Lt will measure precipitates, such as




    carbonate and hydroxide precipitates of mercury(II), chat mighc exist in




    an effluent and dissolve when che effluent is diluted with receiving




    wacer.  If desired, dilution of effluent with receiving water before




    measurement of acid-soluble mercury might be used to determine whecher




    che receiving wacer can decrease che concentration of acid-soluble




    mercury because of sorption.




4.  The acid-soluble measurement should be useful for mosc mecals, thus




    minimizing che number of samples and procedures chat are necessary.




5.  The acid-soluble measurement does noc require filtration at che time of




    collection, as does che dissolved measurement.




6.  The only creacmenc required ac che cime of collection is preservation by




    acidification co pH » 1.5 co 2.0, similar to that required for che cocal




    measurement




7.  Duracions of 10 minuces to 24 hours becween acidification and filcracion




    probably will noc affecc che result substantially.




8.  The carbonate system has a much higher buffer capacicy from pH = 1.5 co




    2.0 than it does from pH * 4 to 9 (Weber and Scumm, 1963).




9.  Differences in pH wichin che range of 1.5 co 2.0 probably will noc affecc




    che result substantially.




10. Afcer acidificacion and filcracion of che sample co isolate the acid-




    soluble mercury, che analysis for total acid-soluble mercury can be




    performed using permanganate and persulface oxidation and cold vapor




    atomic absorption (U.S. EPA, 1983a), as with the cocal raeasuremenc.



                                      4

-------
    Acid-soluble inorganic mercury can be measured by noc breaking down che




    organoraercury compounds before using cold vapor atomic absorpcion.




    Mechylmercury has been measured using gas chromacography (Cappon, 1984;




    Hildebrand, ec al. 1980; Paasivirca, ec al. 1981), chin layer chromaco-




    graphy (Kudo, ec al. 1982), and liquid chroraacography (Case and Kraak,




    1979; MacCrehan and Dursc, 1978).




Thus, expressing aquacic life criceria for mercury in cenns of che acid-




soluble measuremenc has both coxicological and praccical advancages.  On che




ocher hand, because no measuremenc is known co be ideal for expressing




aquacic life criceria for mercury or for measuring mercury in ambienc wacer




or aqueous effluencs, measuremenc of boch cocal acid-soluble mercury and




cocal mercury in ambienc wacer or effluenc or boch raighc be useful.  For




example, there ought be cause for concern if cocal mercury is much above an




applicable limic, even chough cocal acid-soluble mercury is below che limic.




     Unless ocherwise noced, all concencracions reporced herein are expecced




co be essencially equivalent co acid-soluble mercury concencracions.  All




concencracions are expressed as mercury, noc as che chemical cesced.  The




criceria presented herein supersede previous aquacic life wacer quality




criceria for mercury (U.S. EPA, 1976, 1980) because these new criceria were




derived using improved procedures and addicional information.  Whenever




adequately juscified, a national criterion may be replaced by a site-specific




cricerion (U.S. EPA, 1983b), which may include noc only sice-specific




cricerion concencracions (U.S. EPA, I983c), buc also sice-specific duracions




of averaging periods and sice-specific frequencies of allowed exceedences




(U.S. EPA, 1985).  The lacesc liceracure search for information for chis




docuraenc was conducted in May, 1984; some newer informacion was also used.

-------
Acuce Toxicicy co Aquacic Animals



     Table 1 concains che primary acuce coxicicy data for chree classes of




mercury compounds: mercury(II), raethylraercury, and ocher mercury compounds,




chiefly organic.  The laccer information exiscs principally because many of




these compounds were considered for use in creacmenc of diseases and concrol




of paraaices in fish culture, although their source for environmental concern




is from industrial and agricultural uses for fungus control.  Both phenyl-




mercuric acetate and pyridylmercuric acetate have been called PMA.  Tests




have been conducted on different formulations which contain various




percentages of active ingredient and the percentages of active ingredient




given by the authors were used to calculate mercury concentrations.  When  the




percentage of active ingredient was not given for pyridylmercuric acetate, 80




percent was assumed (Allison, 1957).




     The freshwater acute toxicity values indicate that the difference in




sensitivity between different species to a particular mercury compound is  far




greater than the difference  in sensitivity of a particular  species co various




mercury compounds.  For example, the reported acute values  for raercury(II)




range from 2.217 Mg/L for Daphnia pulex to 2,000 ,jg/L for the aquatic stages




of certain insects, with a continual gradation in sensitivity among




intermediate species (Table  3).  On the other hand, Joshi and Rege (1980),




Lock and van Overbeeke (1981) and Matida, et al. (1971) found that various




species were 4 to 31 times more sensitive to various organic mercury




compounds than to mercuric chloride (Table 1).




     MacLeod and Pessah (1973) studied che effect of temperature on  che acute




toxicity of mercuric chloride to rainbow trout.  At 5, 10,  and 15 C, the




LC50s were 400, 280, and 220 ug/L, respectively (Tables 1 and 6).  Clemens




and Sneed (1958b) found a similar effect of temperature on  toxicity  to



                                      6

-------
juvenile channel catfish; ac 10, 16.5, and 24 C che acute values  for phenyL-




mercuric acetate were  1,960, 1,360, and 233 Mg/L» respectively  (Table 6).




     The 28 Genus Mean Acute Values in Table 3 were calculated  as georaecric




means of the available Species Mean Acute Values (Tables 1 and  3).  Acuce




values are available for more than one species in each of cwo genera, and che




range of Species Mean Acute Values within each genus is less than a faccor of




1.6.  On the other hand, a midge was among che most sensitive species,




whereas other insects were the most resistant species.  The most  sensitive




genus, Daphnia, is 756 times more sensitive than the most resistant,




Acroneuria (Table 3).  A freshwater Final Acute Value of 4.857  ^ig/L was




obtained for mercury(II) using the Genus Mean Acute Values in Table 3 and the




calculation procedure described in the Guidelines.  Not enough  data are




available to calculate a Final Acute Value for mechylmercury, but che




available data indicate that it is more acutely coxic than mercury(II).




     Saltwater fishes and invertebrates both show wide ranges of  sensitivi-




ties to mercury(II).  Acute values for fishes range from 36 ;jg/L  for spoc co




1,678 ug/L for winter flounder (Tables 1 and 3).  Among invertebrates a -aysid




has an acute value of 3.5 yg/L, whereas che value for che sofc-shell clam is




400 ug/L.  Of the 29 saltwater genera for which acuce values are  available,




the most sensitive, Mysidopsis, is 479 cimes more sensitive chan  che mosc




resistant, Pseudopleuronectes.   Acuce values are available for  more chan one




species in each of three genera and the range of Species Mean Acuce Values




within each genus is less than a factor of 1.7.  The salcwacer  Final Acuce




Value of 4.125 >jg/L was calculated for raercury(II) from che Genus Mean Acuce




Values in Table 3.

-------
Chronic Toxicity to Aquaeic Animals




     Chronic coxicicy cescs wich Daphnia magna have been conducted on chree




mercury compounds (Table 2).  The renewal and flow-chrough cechniques




produced similar results for raercury(II), buc che renewal technique produced




much higher results for mechylmercury, presumably because of volatility.  In




addition, a chronic test with brook trout on methylmercurtc chloride yielded




a chronic value of 0.5193 tJg/L.  Both an early life-stage test and a




life-cycle test on mercuric chloride  found adverse effects on the fathead




minnow at all concentrations tested including the lowest of 0.23 Jg/L.  For




mercuric chloride the acute-chronic ratio with Daphnia magna is less than 6,




whereas thac with the fathead minnow  is greater than 600.  For methylraercury




che acute-chronic ratio with brook trout is 142.3.




     A chronic value of 1.131 ug/L was obtained in a flow-through life-cycle




exposure of a mysid to mercuric chloride (Table 2).  Groups of 30 juvenile




raysids were reared in each of 5 concentrations for 36 days at 21 C and a




salinity of 30 g/kg.  Effects examined included time co first spawn and




productivity (total number of young/number of available female spawning days




and total number of spawns/number of  available female spawning days).  No




spawning occurred at 2.5 ^ig/L.  Time  to spawn and productivity at 1.6 ,Jg/L




were significantly different from the controls.  The highest concentration ac




which no statistically significant effect on reproductive processes was




detected was 0.8 Jg/L.  Therefore, the chronic limits are 0.8 and 1.6 yg/L




and the chronic value is 1.131 ;Jg/L.  The 96-hr LC50 for this species in the




same study was 3.5 ug/L, giving an acute-chronic ratio of 3.095 (Table 2).




     The species mean acute-chronic ratio for Daphnia magna is 4.498, whereas




that for the mysid is 3.095 (Table 3).  These are sensitive species in fresh




and salt water, respectively, and the four most sensitive species in each



                                      8

-------
wacer are invertebrates.  Thus, ic seems reasonable to use the georaecric mean




of these two values as che Final Acuce-Chronic Ratio (Table 3).  Division of




che Final Acute Values by 3.731 results in freshwater and saltwater Final




Chronic Values of 1.302 and 1.106 ;jg/L, respectively.  Even chough che




fathead minnow was considerably less sensitive chan Daphnia magna in acute




tests, the acute-chronic racio for che fathead minnow is so high chat its




chronic value is below the Final Chronic Value and probably below the Final




Residue Value (see below).  If the acute-chronic ratio of greater chan 649




for che fathead minnow is representative of ratios for other freshwater and




saltwater fishes, then twelve of fourteen tested fish species, including the




rainbow trout, coho salmon, bluegill, and haddock, would have chronic values




below the Final Chronic Value.  Various values for vertebrates in Table 6 are




below the Final Chronic Value or are indicative of large acute-chronic ratios.









Toxicity to AquaticPlants




     Whereas some freshwater plane values for mercury(II) are about 1,000




ug/L (Table 4), effects of raercury(II) and methylmercury have been observed




at concentrations below 10 >jg/L, respectively (Table 6).  Some organomercury




compounds have affected algae at concencrations less chan 1.0 tJg/L (Table 6).




Although freshwater plants are relatively insensitive co raercury(II) and




sensitive to methylmercury, they do not appear to be more sensitive co




methylmercury than freshwater animals.




     Data concerning the toxicity of mercuric chloride co saltwacer planes




are from four studies wich eighc species of algae.  The EC50s (Table 4)




indicace reduccion in growch ac concencracions ranging from 10 co 160 ug/L.




No daca are available concerning che coxicicies of organomercury compounds co




saltwater plants.

Bioaccumulacion




     Bioconcencracion La a function of Che relacive races of uptake aad




depuracion.  The bioconcencracion faccor (BCF) of mercury is high  for  fish




because upcake is relatively fasc and depuracion is very slow.  Thus,  che




biological half-life of mercury in fish is approximacely 2 co  3 years  (de




Freicas, ec al. 1974, 1977; Jarvenpaa, ec al. 1970; Lockharc,  ec al. 1972;




McKira, ec al. 1976; Mellinger, 1973; Ruohcula and Mieccinen, 1975; Sharpe, ec




al. 1977).  Depuracion of mercury is so slow chac, even in che absence of




exposure co mercury, long-cerra reduccion in che concencracion  of mercury in




fish tissue is largely due co dilucion by tissue addicion from growch.




Usually less chan 60 percent of mercury in invercebraces is mechylaced, buc




in fish, except for young fish, usually more chan 70 percenc is raechylaced




(Bache, ec al. 1971; Baluja, ec al. 1983; Busch, 1983; Cappon, 1984; Cappon




and Smith, 1982a,b; Hattula, et al. 1978; Hildebrand, ec al. 1980; Huckabee,




ec al. 1979; Kudo, ec al. 1982; Lucen, ec al. 1980; Paasivirta, ec al.



1983).




     The discribucion of mercury wichin a fish is che result of che raovemenc




of mercury from che absorbing surfaces (gills, skin, and gascroincescinal




cracc), inco che blood,  chen co the incernal organs, and evencually either co




che kidney or bile for recycling or elimination or to muscle for long-cerm




storage.  Aa the tissue concentration approaches steady-state, nee




accumulation rate is slowed either by a reduction in upcake race, possibly




due co inhibicion of membrane cransporc,  or by an increase in depuracion




race,  possibly because of a sacuracion of storage sites,  or both.




     High concentrations of mercury in the slime coac of cercain freshwacer




fishes, such as burboc,  eels, and norchern pike, and in che skin of acucely-




exposed fishes are believed co be due co che mechylacing accivicy of bacceria



                                     10

-------
 prevalent  in  che mucous  coac  (Jernelov,  1968).   In  addicion,  acucely  coxic




 concentrations  of mercury have  been  reported  to  stimulate  secretion of  mucus




 (Baker,  1973; Lock, et al.  1981; McKone,  et al.  1971).  When  acucely  exposed




 fish  are placed in mercury-free water, the skin  quickly loses mercury,




 probably because of elimination of raercury(ll) and  sloughing  of  che slime




 coac  (Burrows and Krenkel,  1973; Burrows, et  al.  1974).   The skin and  mucous




 coac  are in direct contact  with mercury  in water and can accumulate




 proportionately more mercury  during  short exposure  than muscle.  During  long




 exposure there  is sufficient  time for mercury to reach more permanent storage




 sices.




      Because  sorpcion at the  gill surface Is  a major pathway  of  mercury  into




 aquaeic organisms (Frorara, 1977), increases in temperature  and activity  cause




 increases  in  metabolic rate and ventilation rate and, therefore, uptake  race




 (de Freitas and Hart, 1975; Rogers and Beamish,  1981).  The relationship




 between temperature and  tissue  residues  seems co apply primarily before




 sceady-stace  is reached  (Reinert, et al.  1974) but  also co some  excenc ac




 sceady-scace  (Boudou, ec al.  1979; Cember, et al. 1978; Harcung, 1976).  The




 latter is difficult to understand if sceady-scace results  from saturation of




 available binding sites.  Apparently noc only are uptake and  depuration




 accelerated by  temperature  (Ruohcula and Miettinen, 1975), but higher tissue




 residues also occur ac higher temperatures,  posibly because the uptake race




 increases proportionately more  than che depuration race.




      Similarly, low concentrations of dissolved oxygen are likely to  increase




both respiration race and uptake rate.  Larson (1976) found that che  low




concentration of dissolved oxygen in a eutrophic lake forced  fishes into




warmer surface waters to secure adequate oxygen.  The warmer  surface wacer




apparently stimulated metabolic rate and increased mercury uptake.




                                     11

-------
     Increased metabolic race increases noc only vencilacion race but also




energy demand and chus increases food consumption and exposure co mercury




chrough the food chain.  Upcake through both che gills and the digestive




cracc is significant for fish, and some data suggest chat tissue residues are




higher in organisms exposed via both routes than via either separately




(Boudou, ec al. 1979; Phillips and Buhler, 1978).  The relative importance of




uptake from food for various fish species depends on such chings as




assimilation efficiency (Phillips and Gregory, 1979), body size, growth race,




and life span (Sharpe, ec al. 1977), and diec (Murray, 1978).  Although




Murray (1978) did find different concencracions of mercury in different fish




species, Huckabee (1972) and Huckabee, ec al. (1974) found similar concencra-




cions in both forage and game fish in che same environment.




     Haines (1981) reporced chac acid rain cends co scour more mercury  from




che air.  Acidificacion of a body of wacer might also increase mercury




residues in fish even if no new input of mercury occurs, possibly because




lower pH increases vencilacion race and membrane permeability, accelerates




che races of mechylacion and uptake, affects parcicioning between sediment




and wacer, or reduces growch or reproduccion of fish (Akielaszek and Haines,




1981; Fromrn, 1980; Hahne and Krooncje, 1973; Jernelov, 1980; Miller and




Akagi, 1979; Ribeyre and Boudou, 1982; Rudd and Turner,  19835; Scheider, et




al. 1979; Scokes, ec al. 1983; Tsai, ec al. 1975; Wrenn  and MacCrimmon,




1983).  However, Heiskary and Helwig (1933) did noc find a relacion between




pH and mercury in fish.




     The available information (e.g., Boudou and Ribeyre, 1981; Boudou, ec




al. 1977, 1980; de Freitas, ec al. 1981; Hamdy and Prabhu, 1979; Haraelink, ec

1976; Phillips, ec al. 1980; Ribeyre, et al. 1980; Rogers and Beamish, 1982;




Rogers and Qadri, 1982) indicates chac the importance of uptake from food




probably depends on che form and concentration of mercury in the disc and on




the size and metabolic rate of the fish.  Transfer of mercury from fish to




wildlife predators has also been observed (Heinz, et al. 1980; Kucera, 1983;




Wren, et al. 1983).




     The available freshwater BCFs are listed in Tables 5 and 6.  Table 5




contains BCFs only from those studies in which che exposure concentrations




were adequately measured and the tissue residues reached steady-state or the




test lasted longer than 27 days.  Although the BCFs presented in Table 6 do




not meet all these conditions, they do provide information on BCFs for plants




and illustrate the very important influence of temperature on




bioconcentration.




     McKim, et al. (1976) studied the uptake of mechylmercury into various




tissues of brook trout.  At concentrations in water of 0.93, 0.29, 0.09 and




0.03 ^i?/L the resulting concentrations in muscle after 273 days were 10,000,




5,000, 1,900, and 1,000 ug/kg and the corresponding BCFs were 11,000, 17,000,




21,000, and 33,000, respectively.  Because the concentration of mercury in




the muscle did not decrease as much as the concentration in water, che BCFs




increased as the concentration in water decreased.  A possible explanation




for an inverse relationship between concentration in water and BCF is that




steady-state results from saturation of available binding sites (Cember, et




al. 1978).  The maximum concentration in tissue would then be dependent on




the number of available binding sites and would be independent of the concen-




tration of mercury in water.  If the concentration in tissue were constant,




the BCF would be inversely proportional to the concentration in water.




However, neither the concentration in tissue nor the BCF was constant.  The




                                     13

-------
comparable BCFs for the whole body were 10,000, 12,000, 12,000, and 23,000




and are lower than chose for muscle.  The fish were adversely affected ac




0.93 Mg/L. but for boch muscle and whole body, che BCF ac chis concencracion




is in line wich che ocher BCFs.  Even chough concencracions up co 0.29 ^g/L




did noc cause scaciscically significant adverse effeccs, che concencracion of




mercury in fish exposed co 0.03 ug/L were ac che FDA accion level.




     Olson, ec al. (1975) obtained much higher BCFs for raechylmercury wich




che fathead minnow, and the BCF was also concentration-dependent.  As che




concentration in the wacer decreased from 0.247 :Jg/L co 0.018 pg/L, che




concentration in che fish decreased from 10,900 iJg/kg co 1,470 jjg/kg, buc che




BCF decreased from 44,100 co 81,700.  The concrasc between che results wich




che fathead minnow ac 25 C (Olson, et al. 1975) and brook crouc ac 9 co  15 C




(MeKim, ec al. 1976) is one of considerable interest and potential




importance.  The trout were fed pelleted feed, and so had little opportunity




for food chain input.  In contrast, the fathead minnow is a browser and




probably fed noc only on the introduced food buc also on che Aufwuchs growing




in che cesc solution co which mercury had been added.  Thus che higher BCFs




for che fachead minnow might be more represencacive of field sicuacions  in




which fish are exposed co mechylmercury via boch che wacer and food (Phillips




and Buhler, 1978; Phillips and Gregory, 1979; Rogers and Beamish,  1982).




Also, because cemperacure affects bioconcencracion, che fachead minnow might




be more represencacive of commonly consumed warmwacer fishes.




     In a 75-day cest, Niimi and Lowe-Jinde (1984) found 12 rag/kg  in che




whole body of rainbow crouc exposed co 0.15 ;jg mechylmercury/L (0.14 ,jg




mercury/L) in wacer and 18 jjg mercury/kg in food.  The BCF of 85,700 is




higher than the highest BCF obtained by Olson, ec al. (1975).  However,  at




0.012 tig/L and 18 ug/kg, they found 0.053 mg/kg in che crouc.  This BCF  of



                                     14

-------
4,077 is lower than the lowesc BCF obtained by McKim, ec aL. (1976).  Also,




although both McKira, ec al. (1976) and Olson, ec al. (1975)  found higher BCFs




ac lower concencracions in wacer, Niitni and Lowe-Jinde (1984) found jusc che




opposice.




     The FDA accion level for mercury in fish and shellfish  is 1.0 mg/kg




(Table 5), and now only applies Co che mechylmercury in consumed tissues




(U.S. FDA, I984a,b).  In cheir cesc on mechylraercury, McKim, ec al. (1976)




found Chac brook crouc exposed co 0.03 ug/L concained 1 mg/kg in muscle




cissue.  However, in cheir cesc on mechylmercury wich che fachead minnow,




Olson, ec al. (1975) found chac exposure co 0.018 ;jg/L resulced in 1.47 mg/kg




in che fish and a BCF of 81,700.  Use of chis BCF wich che FDA accion level




results in a Final Residue Value of 0.012 ^ig/L for mechylmercury (Table 5).




The concencracion in che fachead minnow is for whole body, buc Heisinger,  ec




al. (1979) found no significanc difference between various body compartments.




Furcher, Huckabee, ec al. (1974; tound cnac all fishes in a  parcicular




environraenc acquired abouc che same concencracions of mercury in both the




whole body and muscle cissue when they were chronically exposed co low




concencracions of mercury.  On che ocher hand, Heiskary and  Helwig (1983)  and




McKim, ec al. (1976) found higher concencracions of mercury  in che edible




portion of fish than in the whole body.  Thus che concentration of mercury in




che muscle of some edible species is likely co exceed che FDA accion level




when exposed to mechylmercury ac a concencracion of 0.012 :-ig/L.




     Although che FDA accion level only applies co mechylmert-ury in fish and




shellfish, it can be used co derive a wacer qualicy cricerion for inercury(II)




because mosc of che mercury in fish is mechylmercury even if che organisms




were exposed co inorganic mercury (de Freicas, ec al. 1974; Jernelov and




Lann, 1971).  A BCF of 4,994 was obtained for mercuric chloride in a




                                     15

-------
life-cycle cesc with che fathead minnow (Snarski and Olson, 1982).  This BCF




is baaed on che concencracion of mercuric chloride in che water and che total




concencracion of organic and inorganic mercury in che tissue.  Even chough




all concentrations tested caused adverse effects and the higher concentra-




tions caused more severe effects, the BCFs were similar at all concentrations




and were lower than those obtained with raethylmercury by McKim, et al. (1976)




and Olson, et al. (1975).  Use of the BCF of 4,994 with the FDA accion level




of 1.0 rag/kg results in a freshwater Final Residue Value of 0.20 jg/L for




mercury(II) (Table 5).  This value of 0.20 |Jg/L derived for mercury(ll)




would, however, be too low if field BCFs are higher than laboratory BCFs, if




waters contain substantial concentrations of raechylraercury, or if mechylacion




processes are accelerated in sediment'.




     Information on the bioconcentration of various mercury compounds by




saltwater animals and plants is included in Tables 5 and 6 and by saltwater




plankton in Table 6.  For mercuric chloride, BCFs ranged from 853 co 10,920




with algae.  In tests with the eastern oyster, BCFs of 10,000, 40,000, and




40,000 were obtained for mercuric chloride, mechylmercuric chloride and




phenylmercuric chloride, respectively (Kopfler, 1974).  These are similar co




the BCFs obtained with freshwater fish, but che BCF of 129 obtained for




mercuric chloride in tail muscle of the American lobster is much lower.




     To protect the marketability of saltwater shellfish for human




consumption, Final Residue Values can be calculated based on the BCFs for che




oyster and the FDA accion level of 1.0 mg/kg.  Accordingly, che Final Residue




Values for mercuric chloride, mechylraercuric chloride, and phenylraercuric




chloride are 0.10, 0.025, and 0.025 iJg/L, respectively.  However, ac chese




concentrations fifty percent of the exposed oysters would probably exceed che

FDA action Level if all the mercury in the body were present as mechyl-
mercury.


Other Data
     Most of the significant freshwater and salcwater resulcs in Table 6 have
already been discussed in connection wich daca in Tables 1-5, but a few
additional iceras deserve special mention.  Comparable cescs wich four species
showed that mercuric cyanide was 0.67 co 50 times as toxic as mercuric
chloride.  Also, Birge, et al. (1979) reported that flow-through casts gave
EC50s nearly two orders of magnitude lower than static tests wich rainbow
trout, catfish, goldfish, and largemouth bass (Table 6).  Bouquegneau (1979)
found that preexposure induced metallochionein production, which then
protected the fish.
     Molybdenum (Yamane and Koizumi, 1982) and vitamin E (Gancher, 1978,
1980) affects the toxicity of mercury to mammals, and probably many consumers
of aquatic organisms, as does selenium (e.g., Alexander, et al. 1979; Berlin,
1978; National Research Council, 1978; National Research Council Canada,
1979; Stopford and Goldwater, 1975; Strom, et al. 1979).  Wobeser, et al.
(1976a,b) found raethylmercury to be much less coxic co mink when they were
fed freshwater drum, Aplodinolus grunniens, containing high mercury tissue
residues than when they were fed a diet co which methylraercury chloride had
been added.  On the other hand, Albanus, et al. (1972) and Charbonneau, et
al. (1974) found similar toxicity to cats when fed similar dietary
concentrations of methylmercury, one as a tissue residue in pike and the
other with methylmercury added to the ration.
     Finley and Stendell (1978) and Heinz (1979a) fed black and mallard
ducks, respectively, food contaminated with raethylmercuric dicyandiamide.
                                     17

-------
These feeding studies extended over cwo and chree generations, respectively,




and demonstrated reduced hatching success and juvenile survival ac mercury




concentrations that were estimated to be equivalent to 0.5 and O.L mg/kg,




respectively, in the natural succulent food of the wild ducks.  These results




were not used to estimate a Final Residue Value based on food for wildlife




because the dicyandiamide compound might not represent che coxicicy of




raethylmercury alone.  Nevertheless, these tests suggest that che Final




Residue Value might be an order of magnitude too high because at least one of




these authors believes that the anion had little effect on the results




(Heinz, I979b).








Unused Data




     Some data on the effects of mercury on aquatic organisms were not used




because the studies were conducted with species chat are not resident in




North America (e.g., Ahsanullah, 1982; Akiyama, 1970; Dial, 1978a,b;




Heisinger and Green, 1975; Jones, 1939a, 1940, 1973, 1975;  Khangaroc, ec al.

and Parashari, 1983; Shaffi, 1981; Srivastava, 1982; van den Broek and




Tracey, 1981; Verraa, et al. 1984), or because che cest species was noc




obtained in North America and was not identified well enough to determine if




it is resident in North America (Hannerz, 1968).  Brown and Ahsanullah (1971)




conducted tests with brine shrimp, which species is coo acypical co be used




in deriving national criteria.  Reviews by Chapman, et al.  (1968), Eisler




(1981), Eisler, et al. (1979), Phillips and Russo (1978), and Thompson,  et




al. (1972) only contain data chac have been published elsewhere.

     The 96-hr values reported by Buikema, et aL. (1974a,b) were subjecc co

Applegace, ec al. (1957) exposed only one or cwo organisms.  Data were noc




used if the node of exposure was inappropriate for deriving water qualicy




criteria (Giblin and Massaro, 1973; Lucu and Skreblin, 1981; Schmidt-Nielson,




ec al. 1977; Weisbart, 1973).  In addition, data were not used if mercury was




a component of an effluent (Wong, et al. 1982) or if the test organisms were




culcured in one water and tested in another (Bringmann and Kuhn, 1982).




Bills, et al. (1977) and Passino and Cotant (1979) did not report any usable




results.  Jones (1935, 1938, 1939b, 1947), Miller (1980, 1981), and Nuzzi




(1972) did not report a clearly defined endpoint.




     Results of some laboratory tests were not used because the test was




conducted in distilled water (McKone, et al. 1971), the quality of the




dilution water or medium was questionable (Brkovic-Popovic and Popovic,




1977a,b; Carter and Cameron, 1973; Kim, et al. 1977a,b; Stary and Kratzer,




1982; Stary, et al. 1982, 1983), or because the test solution or culture




medium contained too auch EDTA which would probably complex mercury




(Gutierrez-Galindo, 1981; Knowles and Zingmark, 1978; Scratcon and Corke,




1979; Stratton, et al. 1979).

Summary




     Data are available on the acuce coxicicy of mercury(II) co 28 genera of




freshwater animals.  Acuce values for invertebrate species range from 2.2




.jg/L for Daphnia pulex to 2,000 ug/L for three insects.  Acuce values for




fishes range from 30 ug/L for the guppy to 1,000 rig/L for che Mozambique




tilapia.  Few data are available for various organoraercury compounds and




mercurous nitrate, and they all appear co be 4 co 31 times more acutely toxic




than mercury(II).




     Available chronic data indicate thac mechylmercury is the most




chronically toxic of che cesced mercury compounds.  Tests on mechylraercury




wich Daphnia magna and brook crouc produced chronic values less than 0.07

National Criteria




     Derivation of a wacer qualicy cricerion for mercury is more complex chan




for mosc mecals because of raechylacion of mercury in sedLuenc, in fish, and




in che food chain of fish.  Apparencly almosc all mercury  currencly being




discharged is raercury(II).  Thus tnercury(II) should be che only  imporcanc

-------
possible cause of acuce coxicicy and che Cricerion Maximum Concencracions can




be based on che acute values for mercury(II).




     The best available daca concerning long-term exposure of fish co




mercury(II) indicates thac concentrations above 0.23 Mg/L caused scatisti-




cally significant effects on the fathead minnow and caused che concentration




of total mercury in the whole body to exceed 1.0 rag/kg.  Although it is noc




known what percent of the mercury in the fish  was methylraercury, it is also




not known whether uptake from food would increase the concentration in the




fish in natural situations.  Species such as rainbow trout, coho salmon, and




especially the bluegill, might suffer chronic  effects and accumulate high




residues of mercury about the same as che fathead minnow.




     With regard to long-term exposure to methylmercury, McKira, et al. (1976)




found that brook trout can exceed the FDA action level without suffering




statistically significant adverse effects on survival, growth, or reproduc-




tion.  Thus for methylmercury the Final Residue Value would be substantially




lower than the Final Chronic Value.




     Basing a freshwater criterion on the Final Residue Value of 0.012 ng/L




derived from the bioconcentration factor of 81,700 for methylraercury with the




fathead minnow (Olson, et al. 1975) essentially assumes chat all discharged




mercury is methylmercury.  On the other hand,  there is che possibility chat




in field situations uptake from food might add to the uptake from water.




Similar considerations apply to the derivation of the saltwater criterion of




0.025 ug/L using the BCF of 40,000 obtained for methylmercury with the




Eastern oyster (Kopfler, 1974).  Because the Final Residue Values for methyl-




mercury are substantially below the Final Chronic Values for mercury(ll), it




is probably not too important that many fishes, including the rainbow trout,
                                     22

-------
coho salmon, bluegill, and haddock might noc be adequately protected by the




freshwater and saltwater Final Chronic Values for mercury(II).




     In contrast to all the complexities of deriving numerical criteria for




mercury, monitoring for unacceptable environmental effects should be




relatively straightforward.  The most sensitive adverse effect will probably




be exceedence of the FDA action level.  Therefore, existing discharges should




be acceptable if the concentration of methylraercury in the edible portion of




exposed consumed species does not exceed the FDA action level.




     The procedures described in the "Guidelines for Deriving Numerical




National Water Quality Criteria for the Protection of Aquatic Organisms and




Their Uses" indicate that, except possibly where a locally important species




is very sensitive, freshwater aquatic organisms and their uses should not be




affected unacceptably if the four-day average concentration of mercury does




not exceed 0.012 ug/L more than once every three years on the average and if




the one-hour average concentration does not exceed 2.4 Mg/L more than once




every three years on the average.  If the four-day average concentration




exceeds 0.012 Mg/L more than once in a three-year period, the edible portion




of consumed species should be analyzed to determine whether the concentration




of methylmercury exceeds the FDA action level.




     The procedures described in the "Guidelines for Deriving Numerical




National Water Quality Criteria for the Protection of Aquatic Organisms and




Their Uses" indicate that, except possibly where a locally important species




is very sensitive, saltwater aquatic organisms  and their uses should noc be




affected unacceptably if the four-day average concentration of mercury does




not exceed 0.025 Mg/L more than once every three years on the average and if




the one-hour average concentration does not exceed 2.1 Mg/L more than once




every three years on the average.  If the four-day average concentration




                                     23

exceeds 0.025 yg/L more chan once in a chree-year period, the edible portion




of consumed species should be analyzed co determine whether the concentration




of methylmercury exceeds the FDA action level.




     EPA believes that a measurement such as "acid-soluble" would provide a




more scientifically correct basis upon which to establish criteria for




metals.  The criteria were developed on this basis.  However, at this time,




no EPA approved methods for such a measurement are available to implement the




criteria through the regulatory programs of the Agency and the Status.  The




Agency is considering development and approval of methods for a measurement




such as "acid-soluble".  Uncil available,  however, EPA recommends applying




the criteria using the total recoverable method.  This has two impacts: (1)




certain species of some metals cannot be analyzed directly because the total




recoverable method does not distinguish between individual oxidation states,




and (2) these criteria may be overly protective when based on the total




recoverable method.




     The recommended exceedence frequency of three years is the Agency's best




scientific judgment of the average amount  of time it will take an unstressed




system to recover from a pollution event in which exposure to mercury exceeds




the criterion.  Stressed systems, for example, one in which several outfalls




occur in a limited area, would be expected to require more time for recovery.




The resilience of ecosystems and their ability to recover differ greatly,




however, and site-specific criteria may be established if adequate justifica-




tion is provided.




     The use of criteria in designing waste treatment facilities requires the




selection of an appropriate wasteload allocation model.   Dynamic models are




preferred for the application of these criteria.  Limited data or other




factors may make their use impractical, in which case one should rely on a




                                     24

-------
steady-state model.  The Agency recommends the interim use of 1Q5 or  IQ1Q for




Criterion Maximum Concentration (CMC) design flow and 7Q5 or 7Q10 for the




Criterion Continuous Concentration (CCC) design flow in steady-state models




for unstressed and stressed systems respectively.  These matters are




discussed in more detail in the Technical Support Document for Water Quality-




Based Toxics Control (U.S. EPA, 1985).
