Toxicity and Metabolism Studies with EPA (Environmental Protection Agency) Priority Pollutants and Related Chemicals in Freshwater Organisms

摘要

Twenty-two chemicals from the EPA priority pollutant list were studied for their acute and/or chronic toxicity to selected freshwater organisms. Freshwater species tested included the fathead minnow (Pimephales promelas), rainbow trout (Salmo gairdneri), bluegill sunfish (Lepomis macrochirus), flagfish (Jordanella floridae), water flea (Daphnia magna), scud (Gammarus pseudolimnaeus), midge (Tanytarsus dissimilis), and green alga (Selenastrum capricornutum). A comparison was made of the metabolism and binding of carbon tetrachloride, chloroform, 1,1,2-trichloroethane, 1,1,2-trichloroethylene and monochlorobenzene by microsomal fractions of rainbow trout livers and of daphnid whole bodies.
