Environmental Contaminants in Biota (ePub)

Dr. W. Nelson Beyer is an ecotoxicologist at the Patuxent Wildlife Research Center, in the U.S. Geological Survey. He earned a doctorate in terrestrial ecology from Cornell University in 1976, studying the natural history of slugs, and remains curious about all manner of living things. With help from colleagues in the U.S. Fish and Wildlife Service, he has examined contaminated sites, studying phytotoxic injury to the chestnut oak forest adjacent to the Palmerton zinc smelters in Pennsylvania, lead poisoning of swans and other waterfowl in the Coeur d'Alene River Basin in Idaho, and zinc poisoning of wild birds at the Tri-State Mining District in Oklahoma, Kansas, and Missouri. Many of his studies have documented the movement of environmental contaminants from soil and sediments into wildlife and through food chains, often showing how ingestion of soil or sediment is the most important route of exposure of lead and related metals to wildlife. Recently he has turned his eye toward sediment ingestion by bottom-feeding fish. He believes in using tissue residues as a means to emphasize injury to animals, basic to wildlife toxicology. His work is usually conducted to support Natural Resource Damage Assessments. He balances his down-to-earth approach to wildlife toxicology, however, with an inordinate fondness for clouds. His daily cycling inspires him, and his wife, Mary, keeps his laboratory running. Dr. James P. Meador is an environmental toxicologist with the National Marine Fisheries Service in Seattle, WA, U.S., which is part of the National Oceanic and Atmospheric Administration (NOAA). Jim has a Ph.D. in aquatic toxicology from the University of Washington and has more than 30 years experience in the field. He has been with NOAA for 20 years and has previously worked at the Scripps Institution of Oceanography and the Naval Oceans Systems Center in San Diego. For many years he has studied the environmental factors that control the bioavailability of contaminants
