CONDUCTING TOXICITY TESTS WITH FRESHWATER ORGANISMS EXPOSED TO DIELDRIN, FLUORANTHENE AND PHENANTHRENE

Several toxicity tests are needed to complete data sets for the numerical national water quality criteria for the protection of aquatic life. This report contains some of the needed tests which are: an acute renewal test with dieldrin exposing a cladoceran, Daphnia magna, acute and chronic flow-through tests with dieldrin exposing rainbow trout, Oncorhynchus mykiss, a chronic renewal test with fluoranthene (without additional UV light) exposing D. magna and acute flow-through and chronic renewal.tests with phenanthrene exposing D. magna. All tests were conducted at the University of Wisconsin-Superior testing facilities according to the proced res recommended by the American Society for Testing and Materials (ASTM)
