Scope

1.1 This test method covers procedures for testing freshwater organisms in the laboratory to evaluate the toxicity of contaminants associated with whole sediments. Sediments may be collected from the field or spiked with compounds in the laboratory.

1.1.1 Test methods are described for two toxicity test organisms, the amphipod Hyalella azteca ( H. azteca) (see ) and the midge Chironomus dilutus (formerly known as C. tentans; Shobanov et al. 1999.() (see ). The toxicity tests are conducted for 10 days in 300-mL chambers containing 100 mL of sediment and 175 mL of overlying water. Overlying water is renewed daily and test organisms are fed during the toxicity tests. Endpoints for the 10-day toxicity tests are survival and growth. These test methods describe procedures for testing freshwater sediments; however, estuarine sediments (up to 15 ppt salinity) can also be tested with H. azteca. In addition to the 10-day toxicity test method outlined in and , general procedures are also described for conducting 10-day sediment toxicity tests with H. azteca (see ) and C. dilutus (see ).

Note 1

Morphological comparison of populations of Chironomus (Camptochironomus) tentans(Fabricius) from Europe, Asia, and North America have confirmed cytogenetic evidence that two distinct species inhabit the Palearctic and Nearctic under this name. The Palearctic species is the true C. tentans and the Nearctic populations constitute a new species described under the name Chironomus (Camptochironomus) dilutus (Shobanov et al. 1999 ()."

1.1.2 Guidance for conducting sediment toxicity tests is outlined in for Chironomus riparius, in for Daphnia magna and Ceriodaphnia dubia, in for Hexagenia spp., in for Tubifex tubifex, and in for the Diporeia spp. Guidance is also provided in for conducting long-term sediment toxicity tests with H. azteca by measuring effects on survival, growth, and reproduction. Guidance is also provided in for conducting long-term sediment toxicity tests with C. dilutus by measuring effects on survival, growth, emergence, and reproduction. outlines the data that will be needed before test methods are developed from the guidance outlined in to for these test organisms. General procedures described in Sections for sediment testing with H. azteca and C. dilutus are also applicable for sediment testing with the test organisms described in to .

1.2 Procedures outlined in this test method are based primarily on procedures described in the United States Environmental Protection Agency (USEPA) ( ), Test Method E 1367, and Guides E 1391, E 1525 and E 1688.

1.3 Additional research and methods development are now in progress to: (1) evaluate additional test organisms, (2) further evaluate the use of formulated sediment, (3) refine sediment dilution procedures, (4) refine sediment toxicity identification evaluation (TIE) procedures (), (5) refine sediment spiking procedures, (6) develop in situ toxicity tests to assess sediment toxicity and bioaccumulation under field conditions, (7) evaluate relative sensitivities of endpoints measured in tests, (8) develop methods for new species, (9) evaluate relationships between toxicity and bioaccumulation, and (10) produce additional data on confirmation of responses in laboratory tests with natural populations of benthic organisms. Some issues that may be considered in interpretation of test results are the subject of continuing research including the influence of feeding on bioavailability, nutritional requirements of the test organisms, and additional performance criteria for organism health. See Section for additional detail. This information will be described in fut......
