Assessment of sediment contamination, acute toxicity, and population viability of the estuarine amphipod Leptocheirus plumulosus in baltimore harbor, maryland, USA
Abstract In Chesapeake Bay, Maryland, USA, some of the most contaminated sediments are found in the highly industrialized Baltimore Harbor—Patapsco River area. As part of a comprehensive assessment of sediment quality in this system, sediment toxicity was assessed in 10‐d acute tests with the estuar...
