The goal of this report is to compare the U.S. EPA approved Leptocheirus plumulosus 10-d acute and 28-d chronic sediment test methods with sediment toxicity test methods used in the Ambient Toxicity Assessment program. The toxicity of estuarine and freshwater sediments was evaluated during the late summer/early fall of 1998 at four stations in the Choptank River and six stations in the Anacostia River. Sediment samples from these stations were collected and split between two laboratories. The Ambient Toxicity Assessment Program methods included the 10-d sheepshead minnow Cyprinodon variegatus embryo/larval test and 20-d survival and growth tests (with 10-d survival data) with the estuarine amphipods L. plumulosus and Lepidactylus dytiscus, the freshwater amphipod Hyalella azteca, and the polychaete worm Streblospio benedicti. These tests were conducted by Old Dominion University's Applied Marine Research Laboratory (AMRL). The U.S. EPA L. plumulosus tests were conducted by the University of Maryland's Wye Research and Education Center (WREC). The 10-d static acute test used mortality as the endpoint while the 28-d static-renewal exposure used mortality, growth, and reproduction as endpoints.
