Introduction*

     Parathion** is one of several organophosphorus compounds developed to

replace organochlorine pesticides.  Its use is primarily as a domestic

and agricultural insecticide.  Its direct use in aquatic environments is

most often in conjunction with mosquito abatement projects as a larvicide.

     The major commercial formulation of parathion is an emulsifiable

concentrate, within which the percentage of active ingredient can vary

considerably.  This results in a large percentage of often unspecified

ingredients, many used as carriers, in the commercial formulation.  These

ingredients are considered inert.  Although no studies have compared relative

toxicities of technical grade parathion and its emulsifiable concentrate,

other organophosphorus insecticides (e.g., chlorpyrifos) have been shown

to differ significantly in this regard.  For this reason, the effect of

the inert ingredients can not be discounted.

     Numerical water criteria are derived herein solely for the chemical

parathion.  Although some data obtained from studies using formulations

are discussed, only data derived from toxicity tests utilizing technical

grade parathion are used in deriving criteria.

     The toxic effect of parathion is the result of metabolic conversion

to its oxygen analogue, parathion-oxon, and its subsequent inhibitive

interaction with various enzyme systems (e.g., cholinesterases, carboxylases,

acetylcholinesterases, mitochondrial oxidative phosphorylation).  Its
*  An understanding of the "Guidelines for Deriving Numerical National Water
   Quality Criteria for the Protection of Aquatic Organisms and Their Uses"
   (Stephan et al. 1985), hereafter referred to as the Guidelines, is necessary
   in order to understand the following text, tables, and calculations.

** Parathion refers to QfQ-diethyl 0-p-nitrophenyl phosphorothionate, and
   is synonymous with(ethyl parathion.

-------
activity with acetylcholinesterase (AChE) is generally accepted to be its




most critical toxic effect.  AChE inhibition results in accumulation of




the neurotransmitter, acetylcholine, in synapes, disrupting normal neural




transmission.  Although in fish even substantial reductions in brain AChE




activity have not always been fatal, the effect of this condition on




normal activity (e.g., feeding, reproduction, predator-prey relationships.




etc.) in nature is not known.  Parathion has also been demonstrated to




produce teratogenic effects in fish embryos (Solomon 1977; Solomon and




Weis 1979; Tomita and Matsuda 1961).




     Although less persistent than organochlorine compounds, parathion




has a great affinity for organic complexes, and is quickly sorbed to




sediments and suspended material.  Miller et al. (1967) observed a rapid




decrease in water concentration after parathion application and attributed




it to degradation.  It is more likely that sorbtion processes contributed




greatly to this observation.  Its persistence is dependent on chemical




hydrolysis (Faust 1972, 1975; Gomaa and Faust 1971) and biodegradation




(Amed and Casida 1958: Mackiewicz et al. 1969; Zuckerman et al. 1970).




Working with natural lake sediments, Graetz et al. (1970) reported that




the portion of parathion degradation attributable to abiological means




was negligible.  Movement and persistence of parathion has been described




in a natural pond (Mulla et al. 1986; Nicholson et al. 1962) and in a model




stream (Laplanche et al. 1981).  Several studies report parathion residues




in water (Braun and Frank 1980; Dick 1982; Harris and Miles 1975; Greve




et al. 1972; Rannan and Job 1979; Sethunathan et al. 1977) and in biota




(Chovelon et al. 1984; Haddadin and Alawi 1974; Hesselberg and Johnson




1972; Perry et al. 1983).

-------
     All concentrations herein are expressed as parathion, not as the




material tested.  Whenever adequately justified, a national criterion may




be replaced by a site-specific criterion (U.S. EPA 1983a), which may




include not only site-specific criterion concentrations (U.S. EPA 1983b).




but also site-specific durations of averaging periods and site-specific




frequencies of allowed exceedences (U.S. EPA 1985).  The latest literature




search for information for this document was conducted in February, 1985;




some newer information was also used.






Acute Toxicity to Aquatic Animals




     Data used in calculation of freshwater criteria for parathion are




found on Table 1.  Thirty-five species are represented, including 13 fish.




10 insects, and 9 crustaceans.  Organisms representing a range of ecological




and habitat types are included.




     Ranked Genus Mean Acute Values (Table 3) for the twenty-eight genera




range from 0.47 Mg/L for a cladoceran to 5,230 Mg/L for two tubifid




worm species.  Invertebrates are represented by the 15 most sensitive




genera.  Of the remaining 20 genera, only 4 are invertebrates, and this




includes 2 tubifid worms which appear to be greatly more resistant to




parathion than any other organism reported on.




     The most striking disparity of values within a species on Table 1 is




for the crayfish, Orconectes nais.  Early instar lifestages are 375 times




more susceptible to parathion intoxication than adults (LC50 = 0.04 and




15. pg/L, respectively).  Considering only this early instar, -Orconectes




nais is the most sensitive species reported on.  No other values for




early instar decapods are available to suggest whether this relationship




is valid beyond this species.

-------
     Relative toxicity to parathion (Table 3) may be influenced by




taxonomic differences, making invertebrates more susceptible.  This




relationship could also be an artifact of size differences, with smaller




organisms, supposedly with higher metabolisms, being more susceptible.




There is a general increase in size with increased ranking on Table 3.




It appears that centrarchids are more susceptible to parathion than




salmonids, although this may be influenced by salmonids being cultured at




a lower temperature.  Banas and Sprague (1981) report no effect on LC50




in rainbow trout acclimated to low levels of parathion.




     Final Acute Value is calculated to be 0.5489 |Jg/L, resulting in




a Criterion Maximum Concentration for parathion of 0.2745 Mg/L.  With the




exception of early instar crayfish, Orconectes nais, this value should be




adequately protective of all organisms reported on.






Chronic Toxicity to Aquatic Animals




     Data used to determine Final Chronic Value for parathion are found




on Table 2.  Information is available from a single study, reported in




two sources (Spacie 1976; Spacie et al. 1981).  Although this study




reports chronic toxicity in three aquatic invertebrates and three fish.




because of experimental problems (primarily high control mortality), only




chronic values for the fathead minnow and the bluegill are used in




calculation of the Final Acute-Chronic Ratio and Final Chronic Value.




Much chronic data from this study reports LC50 data only and it is not




known whether this is the most sensitive parameter relating to chronic




intoxication.  Many of these values occur on Table 5.  No appropriate data




on chronic toxicity to parathion is available for arthropods.




     Chronic exposure in bluegill larvae produced no statistically




significant effect on growth (in length) at 30, 60, and 90 days.  There





                                    4

-------
was also no statistically significant effect on number of eggs spawned,




percent hatch, and survival of larvae at 7, 14, 21, and 30 days.




     In brook trout embryos LC50 was 75.0 pg/L (duration not stated)




after correction for control mortality, when considering percent hatch of




19 day old embryos.  This is 4.2% of the 96 hr LC50 for the species.  At




10. pg/L, percent hatch was reduced but surviving embryos were normal.




At greater than 32 Mg/L, developmental abnormalities were common.




     Fathead minnows were reported to be significantly affected by chronic




exposure to parathion at 9.0 *Jg/L, with a chronic value of 6.3 ;Jg/L.  Acute-




Chronic Ratio for fathead minnows is 79.4.  Chronic value in bluegills is




0.24 Mg/L with an Acute-Chronic Ratio of 2125 (Table 2).  Both fish were




cultured at approximately equal temperature.  Acute toxicity to parathion




appeared to be greater in centrarchids (Table 1), therefore, the large




Acute-Chronic Ratio in bluegills may be indicative of high sensitivity




within this taxon.




     Geometric mean of the two Acute-Chronic Ratios results in a Final




Acute-Chronic Ratio of 410.8.  Division of the Final Acute Value (Table




3) by this factor results in a Final Chronic Value of 0.0013 jJg/L.  This




parathion concentration is below the sensitivity limit of most analytic




methods.  Chronic toxicity data for a freshater arthropod were not available,




therefore were not used in these calculations.






Toxicity to Aquatic Plants




     No data is available on the relative toxicity of varying concentrations




of parathion to freshwater aquatic plants.  A single study (Cole and




Plapp 1974) reported the effect of various initial cell concentrations (1




to 1000 |jg algae/ml) at a single parathion level (1000 pg/L) in terms of




growth and photosynthesis in a green alga. Chlorella pyrenoidosa (Table 5).





                                    5

-------
They reported increased growth inhibition with lower cell concentrations.




With a single parathion dose, specific photosynthesis was greater in




treated cultures, although with multiple doses photosynthesis was strongly




inhibited with greatest effect at lowest cell concentrations.






Bioaccumulation




     All available bioaccumulation data comes from a single study, reported in




two sources (Spacie 1976, Spacie et al. 1981).  Bioaccumulation factors (BAF)




are reported in four fishes.  Factors for brook trout, fathead minnows and




bluegills are found in Table 4.  Addition factors, not appropriate for inclu-




sion in Table 4, are available for brown trout, brook trout, and bluegills




(Table 5).




     In brook trout,"average BAF at 180 days is 392, and at 260 days is




105.9.  From Table 5, 4.75 day, 5.8 day, and 6.0 day BAFs are reported to




be 102.5, 301.5, and 192.5, respectively, indicating rapid uptake of




parathion. but unstable residue levels.




     At 260 days, BAF for fathead minnows averages 111.4, with a range of




32.9 to 201.4.  At 64 hours, BAF in brown trout averaged 69 (Table 5).  A




single bluegill produced a BAF of 27 in 560 days; at 46, 70, and 72 hrs.




factors of 253, 311, and 462 were reported (Table 5).




     There is considerable variation in BAF data.  This most likely is the




result of rapid metabolism of parathion in fish or other metabolic factors.




     No U.S. FDA action level has been set for parathion, therefore no




Final Residue Value is calculated.






Other Data




     Other data on the effects of parathion on aquatic organisms are




found on Table 5.  The majority of entries are LC50 values for durations




other than 96 hours.

-------
     A 24 hour LC50 for a non-resident snail is the only toxicity data




available for the family Mollusca.  This species was very resistant, with




an LC50 of 8090 Mg/L.  For a cladoceran, Daphnia magna, 0.34 pg/L




resulted in a 50Z reproductive impairment (Spacie 1978; Specie et al




1981).  In six coleopteran species, Ahmed (1977) observed a range in 24




hr LC50s from 1.8 |jg/L to 40 pg/L.




     Because of its wide use as a mosquito larvicide, many studies have




tested mosquito larva.  Standard methods commonly adhered to using mosquito




larvae prescribe a 24 hour test duration, making most mosquito larvae




studies inappropriate for consideration in deriving numerical criteria.




The three Aedes species in Table 5 have a mean LC50 of 14.8 pg/L,




Anopheles species 24 hour LCSOs average 5.9 pg/L, and this value for




Culex species is 3.1 jJg/L.




     Several studies have reported associated effects of parathion exposure.




Kynard (1974) observed avoidance of parathion by mosquitofish in the




laboratory, although the significance of this finding under natural




conditions is unknown.  Weiss (1961) reports on fish brain AChE as




inhibition in several freshwater species.  Effects on locomotor behavior




in goldfish, bluegills, and largemouth bass are reported by Rand (1977a, b)




and Rand et al. (1975).  Sun and Taylor (1983) studied effects of parathion




on acquisition and retention of a conditioned response in goldfish.




     Interaction of parathion toxicity has to be examined with a detergent




(Solon and Nair 1970; Solon et al. 1969), herbicides (Lichtenstein et




al. 1975), and an N-alkyl compound, SKF-525A (Gibson and Ludke 1973).




Ludemann and Herzel (1973) report changes in ambient parathion concentrations




under static conditions with and without aeration, and with and without




fish.  Without fish or aeration, parathion level dropped 22% in 96 hours.

-------
When fish were added, levels dropped 54% in 96 hours.  With both fish and

aeration, 67Z reduction was observed.  Other studies on the persistence

of parathion in water include Mulla (1963) and Dortland (1980).

     Several studies evaluated the effectiveness of biomonitoring of

effluents using trout in detecting pollutants including parathion (Jung

1973; Morgan 1976; Van Hoof 1980).  Morgan (1977) was able to detect

parathion concentrations at 15Z of the fishes 48 hour LC50.  Mount and

Boyle (1969) examined the use of blood parathion residues to diagnose

causes of fish kills.

     A field study by Ghetti and Gorbi (1985) reported the effects of a

simulated parathion spill in a stream.  Field studies by Gasith and Perry

(1980, 1982) and Grzendz et al. (1962) reported community effects of parathion

application to a pond.  Warnick et al. (1966) noted increases in water con-

centrations of organochlorine compounds correlated with parathion application

in a natural pond.  They postulated the source of these compounds to be the

release from decomposing tissues of intoxified organisms.

Unused Data

     Some data on the effects of parathion on aquatic organisms were not

used because the studies were conducted with species that are not resident

in North American (e.g., Bellavere and Gorbi 1984; Dortland 1980; Gupta

et al. 1979; Hashiomoto and Nishiuchi 1981; Nishiuchi and Hashimoto 1967;

Nishiuchi and Yoshida 1972; Panwar et al. 1976; Siva Prasada et al. 1983)

or because the test species was not obtained in North America and was not

identified well enough to determine if it is resident in North America

(e.g., Lahav and Sarig 1968).  Tarpley (1958) conducted tests with brine

shrimp, which species are too atypical to be used in deriving national

criteria.  Data were not used if parathion was a component of a mixture

(e.g., Macek 1975).
                                    8

-------
     Anderson (1959),  Henderson et al.  (1959), LeBlanc (1984), Ramke




(1969), Sato and Kubo (1965), Surber (1948), and Tarzwell (1959a,  b) only




present data that have been published elsewhere.  Juhnke and Ludetnann




(1978) and Gutierrez et al. (1977) present only results.  Gaufin et al.




(1961) and Ludemann and Neumann (1961) cite no LC50 data.  Some studies




were not used because of inadequate description of method (e.g., Mulla 1980)




or materials (e.g., Gillies et al. 1974; Hart and Womeldorf 1977;  Lahav




and Sarig 1969; Leva11en and Wilder 1962: Micks and Rougeau 1977;  Moore




1970; Wilder 1977; Wilder and Schaefer 1969; and Zboray and Gutierrez (1979).




     Data were not used if the organisms were exposed to parathion by




injection or gavage or in food (e.g., Benke et al. 1973, 1974; Hasimoto




and Fukami 1969; Loeb and Kelly 1963  and Murphy et al. 1968).




     Chambers (1976); Dortiand (1978); Dortland et al. (1976): Estenik




and Collins (1979): Goldsmith et al. (1976); Hiltibran (1974, 1982);




Huddart (1978); Ludke et al. (1972); McDonald and Fingerman (1979);




Nollenberger (1982); Nollenberger et al. (1981); Weiss (1959); Weiss and




Gakstatter (1964, 1965): Whitmore and Hodges (1978); and Yahalomi and




Perry (1981) only exposed enzymes or cell cultures or conducted other




biochemical or histological studies.




     Results of some laboratory tests were not used because the tests




were conducted in distilled or deionized water without addition of




appropriate salts (e.g., Burchfield and Storrs 1954; Carlson 1978;




Goldsmith and Carlson 1979; Lewallen 1959, 1962; Lichtenstein et al.




1966; and Yasuno et al. 1965).




     Hughes (1970, 1973) did not acclimate the test organisms to the




dilution water for a long enough period of time.  Laboratory studies




using formulations of parathion were not used (e.g., Alexander et al.




1982; Basak and Konar 1976a, b; Chang and Lange 1967; Davey et al. 1976




                                    9

-------
Gaufin et al. 1965; Hilsenhoff 1959: Labrecque et al. 1956; Mohamed and Gupta




1984: Pawar et al. 1982; Singh and Singh 1981, Sreenivasen and Swaninathan




1967; Srivastava et al. 1977, Venna et al. 1981).  Field studies on




parathion which did not measure concentrations were not used (e.g., Ahmed




and Washino 1977; Benge and Fronk 1970; Chang and Lange 1967; Davey and




Meisch 1977; Davey et al. 1976; Gahan 1957; Grigarick and Way 1982;




Labrecque 1956? Mulla and Isaak 1961; Mulla et al. 1963, 1964. 1978:




Myers et al. 1969; Stewart 1977).




     High control mortalities occurred in tests reported by Fleming et




al. (1982).  High pesticide residues were found in field collected worms




by Naqvi (1973) .




     Microcosm studies were not used (e.g., Dortland 1980; Francis et al.




1980: Miller et ai. 1966; Yu and Sanborn 1975).




     Results of laboratory bioconcentration tests were not used if the




test was not flow-through or renewal (e.g., Verma and Gupta 1976).




A bioconcentration study by Schmidt and Weidhaas (1961) was not used because




radio-labeled parathion was not adequately identified as the source of




residue radioactivity.






Summary




     The acute values for thirty-five species in twenty-nine genera range




from 0.47 pg/L for a cladoceran to 5230 Mg/L for two species of tubifid




worm.  The early instar of a crayfish, Orconectes nais was the most




sensitive organism reported with an acute value of 0.04 Mg/L-  Invertebrates




appear to be more sensitive, although this could be related to their




smaller size.  Centrarchids are more sensitive than salmonids, although




differences in culture temperature could effect this relationship.
                                    10

-------
       Chronic  toxicity values  are  available  for  two  fish  species, bluegills




  and  fathead minnows,  with  chronic values  of 0.24  pg/L  and 6.3  pg/L,




  respectively.   Final  Acute-Chronic  Ratio  was 410.8.  Final Chronic Value




  is calculated to be 0.0013 yg/L>  which  is below detection limits.




       No information is available  on the toxicity  of  parathion  to freshwater




  aquatic plants.   Bioconcentration factors are reported in four fish




  species.   Average BCF for  the data  set  is 186.7.  Wide variation occurs




  in BCF data possibly  due to metabolism  of parathion  by fish.






  National  Criteria




       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 parathion  does not exceed(s0.0013 pg/L^more than once  every  three years




  on the average or if  the one-hour average concentration  does not exceed




(_0.2745 (Jg/L\more than once  every  three  years on the  average.




       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 not be  affected unacceptably if  the  four-day  average  concentration




  of parathion does not exceed  AAA  (Jg/L more  than once every three years on




  the  average and  if the one-hour average concentration  does not exceed yyy




  Mg/L more than once every  three years on  the average.




       The  allowed excursion  frequency of thee years is  based  on the Agency's




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





                                      11

-------
aquatic ecosystem to recover from a pollution event in which exposure to




parathion exceeds the criterion.  The resilience of ecosystems and their




ability to recover differ greatly, however, and site-specific criteria




may be established if adequate justification is provided.




     The use of criteria in designing waste treatment facilities requires




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 must rely




on a steady-state model.  The Agency recommends interim use of 1Q10 for




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




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




models.  These matters are discussed in more detail in the Technical




Support Document for Water Quality-Based Toxics Control (U.S. EPA 1985)




and the Design Flow Manual (U.S. EPA 1986).
