Sedimentsmay be collected from the field or spiked with compounds inthe laboratory. General guidance is presented in Sections 1-151to 15 for conduc

Specific guidance for conducting 10-dsediment toxicity tests with estuarine or marine amphipods isoutlined in Annex A1 and specific guidance for conducting28-d sediment toxicity tests with Leptocheirus plumulosus isoutlined in Annex A2.

5、1.2 Procedures are described for testing estuarine or marineamphipod crustaceans in 10-d laboratory exposures to evaluatethe toxicity of contaminants associated with whole sediments(Annex A1; USEPA 1994a (1). Sediments may be collectedfrom the field or spiked with compounds in the laboratory. Atoxic

6、ity method is outlined for four species of estuarine ormarine sediment-burrowing amphipods found within UnitedStates coastal waters. The species are Ampelisca abdita,amarine species that inhabits marine and mesohaline portions ofthe Atlantic coast, the Gulf of Mexico, and San Francisco Bay;Eohaustor

7、ius estuarius, a Pacific coast estuarine species;Leptocheirus plumulosus, an Atlantic coast estuarine species;and Rhepoxynius abronius, a Pacific coast marine species.Generally, the method described may be applied to all fourspecies, although acclimation procedures and some test condi-tions (that is

8、, temperature and salinity) will be species-specific(Sections 12 and Annex A1). The toxicity test is conducted in1-L glass chambers containing 175 mL of sediment and 775mL of overlying seawater. Exposure is static (that is, water isnot renewed), and the animals are not fed over the 10-dexposure peri

The endpoint in the toxicity test is survivalwith reburial of surviving amphipods as an additional measure-ment that can be used as an endpoint for some of the testspecies (for R. abronius and E. estuarius). Performance criteriaestablished for this test include the average survival of amphi-pods

10、 in negative control treatment must be greater than orequal to 90 %. Procedures are described for use with sedimentswith pore-water salinity ranging from 0ooo to fully marine.1.3 A procedure is also described for determining thechronic toxicity of contaminants associated with whole sedi-ments with t

11、he amphipod Leptocheirus plumulosus in labora-tory exposures (Annex A2; USEPA-USACE 2001(2). Thetoxicity test is conducted for 28 d in 1-L glass chamberscontaining 175 mL of sediment and about 775 mL of overlyingwater. Test temperature is 25 6 2C, and the recommendedoverlying water salinity is 5ooo

12、6 2ooo (for test sediment withpore water at 1ooo to 10ooo)or20ooo 6 2ooo (for testsediment with pore water 10ooo). Four hundred millilitres ofoverlying water is renewed three times per week, at whichtimes test organisms are fed. The endpoints in the toxicity testare survival, growth, and reproductio

However, the salinityof the overlying water for tests with these two species can beadjusted to a specific salinity of interest (for example, salinityrepresentative of site of interest or the objective of

More importantly, thesalinity tested must be within the tolerance range of the testorganisms (as outlined inAnnexA1 andAnnexA2). If tests areconducted with procedures different from those describ

This information will bedescribed in future editions of this standard.1.8 Although standard procedures are described in A

While standard procedures aredescribed in this standard, further inve

Some ofthese issues include the effect of shipping on organism sensi-tivity, additional performance criteria for organism health,sensitivity of various populations of the same test species, andconfirmation of responses in la

Results of tests, eventhose with the same species, using procedures different fromthose described in the test method may not be comparable andusing these different procedures may alter bioavailability.Comparison of results obtained using modified versions ofthese procedures might pr

If tests are conducted with proceduresdifferent from those described in this test method, additionaltests are required to determine comparability of results. Gen-eral procedures descri

Further-mor

34、e, no one organism is best suited for all sediments. Thefollowing criteria were considered when selecting test organ-isms to be described in this standard (Table 1 and GuideE 1525). Ideally, a test organism should: (1) have a toxicologi-cal database demonstrating relative sensitivity to a range ofco

35、ntaminants of interest in sediment, (2) have a database forinterlaboratory comparisons of procedures (for example,round-robin studies), (3) be in direct contact with sediment, (4)be readily available from culture or through field collection, (5)be easily maintained in the laboratory, (6) be easily i

36、dentified,(7) be ecologically or economically important, (8) have a broadgeographical distribution, be indigenous (either present orhistorical) to the site being evaluated, or have a niche similar toorganisms of concern (for example, similar feeding guild orbehavior to the indigenous organisms), (9)

37、 be tolerant of abroad range of sediment physico-chemical characteristics (forexample, grain size), and (10) be compatible with selectedexposure methods and endpoints (Guide E 1525). Methodsutilizing selected organisms should also be (11) peer reviewed(for example, journal articles) and (12) confirm

38、ed with re-sponses with natural populations of benthic organisms.1.11.2 Of these criteria (Table 1), a database demonstratingrelative sensitivity to contaminants, contact with sediment,ease of culture in the laboratory or availability for field-collection, ease of handling in the laboratory, toleran

39、ce tovarying sediment physico-chemical characteristics, and confir-mation with responses with natural benthic populations werethe primary criteria used for selecting A. abdita, E. estuarius,L. plumulosus, and R. abronius for the current edition of thisstandard for 10-d sediment tests (Annex A1). The

40、 specieschosen for this method are intimately associated with sediment,due to their tube- dwelling or free-burrowing, and sedimentingesting nature.Amphipods have been used extensively to testthe toxicity of marine, estuarine, and freshwater sediments(Swartz et al., 1985 (10); DeWitt et al., 1989 (11

41、); Scott andE136703e12Redmond, 1989 (12); DeWitt et al., 1992a; Schlekat et al.,1992 (13). The selection of test species for this standardfollowed the consensus of experts in the field of sedimenttoxicology who participated in a workshop entitled “TestingIssues for Freshwater and Marine Sediments”.

42、The workshopwas sponsored by USEPA Office of Water, Office of Scienceand Technology, and Office of Research and Development, andwas held in Washington, D.C. from 16-18 September 1992(USEPA, 1992 (14). Of the candidate species discussed at theworkshop, A. abdita, E. estuarius, L. plumulosus, and R.ab

43、ronius best fulfilled the selection criteria, and presented theavailability of a combination of one estuarine and one marinespecies each for both the Atlantic (the estuarine L. plumulosusand the marine A. abdita) and Pacific (the estuarine E.estuarius and the marine R. abronius) coasts. Ampelisca ab

44、ditais also native to portions of the Gulf of Mexico and SanFrancisco Bay. Many other organisms that might be appropri-ate for sediment testing do not now meet these selection criteriabecause little emphasis has been placed on developing stan-dardized testing procedures for benthic organisms. For ex

45、-ample, a fifth species, Grandidierella japonica was not se-lected because workshop participants felt that the use of thisspecies was not sufficiently broad to warrant standardization ofthe method. Environment Canada (1992 (5) has recommendedthe use of the following amphipod species for sediment tox

46、icitytesting: Amphiporeia virginiana, Corophium volutator, Eo-haustorius washingtonianus, Foxiphalus xiximeus, and Lep-tocheirus pinguis. A database similar to those available for A.abdita, E. estuarius, L. plumulosus, and R. abronius must bedeveloped in order for these and other organisms to be inc

47、ludedin future editions of this standard.1.11.3 The primary criterion used for selecting L. plumulo-sus for chronic testing of sediments was that this species isfound in both oligohaline and mesohaline regions of estuarieson the East Coast of the United States and is tolerant to a widerange of sedim

48、ent grain size distribution (USEPA-USACE2001 (2), Annex Annex A2). This species is easily cultured inthe laboratory and has a relatively short generation time (thatis, about 24 d at 23C, DeWitt et al. 1992a (6) that makes thisspecies adaptable to chronic testing (Section 12).1.11.4 An important cons

49、ideration in the selection of spe-cific species for test method development is the existence ofinformation concerning relative sensitivity of the organismsboth to single chemicals and complex mixtures. Several studieshave evaluated the sensitivities of A. abdita, E. estuarius, L.plumulosus,orR. abronius, either relative to one another, or toother commonly tested estuarine or marine species. For ex-ample, the sensitivity of marine amphipods was compared toother species that were used in generating saltwater WaterQuality Criteria. Seven amphipod genera,
