Environmental contaminants in bald eagles in the Columbia River Estuary Environmental contaminants in bald eagles in the Columbia River Estuary
Eggs, blood, and carcasses of bald eagles (Haliaeetus leucocephalus) and fish were collected and breeding success of eagles was monitored in the Columbia River estuary, 1980-87, to determine if contaminants were having an effect on productivity. High levels of dichloro diphenyl dichloroethylene (DDE), polychlorinated biphenyls (PCB's), and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) were...

Selenium in wetlands and waterfowl foods at Kesterson Reservoir, California, 1984 Selenium in wetlands and waterfowl foods at Kesterson Reservoir, California, 1984
Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and selenium from farmland in the San Joaquin Valley of California. The accumulation of selenium in wetlands and waterfowl foods at Kesterson was investigated during May, August, and December of 1984. High concentrations of selenium were found in water, sediments, terrestrial and...
