Abstract:

Three proposed U.S. Environment Protection Agency sediment toxicity tests were evaluated using Great Lakes sediments. This report provides a technical evaluation of the test methods prior to their incorporation into a regulatory testing program. Tests included a solid phase bioassay using Hyalella azteca 10-day survival and two elutriate tests using Pimephales promelas 7-day survival and growth and Daphnia magna 21-day survival and reproduction. Sediments from four separate dredging projects Toledo Harbor, Michigan City Harbor, Grand Haven Harbor, and St. Joseph Harbor were evaluated. Test methods were evaluated with technical validity, regulatory applicability, and logistical requirements taken into consideration.
