Written as a complement to the definitive work selenium in the Environment (Marcel Dekker, Inc.). Presents basic and the most recent applied research developments in selenium remediation-emphasizing field investigations as well as covering topics from analytical methods and modeling to regulatory aspects from federal and state perspectives.
Federal and state perspectives on regulation and remediation of irrigation-induced selenium problems; methods of analysis for the determination of selenium in biological, geological and water samples; analytical detection of selenium in water, soil and plants; sequential supplementation of fertilizers on human nutrition and selenium status; effects of selenium supplementation of field crops; selenium metabolism in grazing ruminants - deficiency, supplementation and environmental implications; environmental implications of uses of selenium with animals; supplementation of selenium in the diets of domestic animals; mass balance approach to selenium cycling through the San Joaquin Valley - from source to river to bay; selenium sources and effects of biota in the Green River Basin of Wyoming, Colorado, and Utah; selenium and salinity concerns in the Salton Sea area of California; selenium cycling in estuarine wetlands - overview and new results from the San Francisco bay; selenium accumulation in a wetland channel, Benton Lake, Montant; selenite sorption by coal mine backfill materials in the presence of organic solutes; pathology of selenium poisoning in fish; selenium effects on endangered fish in the Colorado River basin; selenium poisoning of fish and wildlife in nature - lessons from 12 real-world experiences; magic numbers, elusive lesions - comparative pathology and toxicology of selenosis in waterfowl and mammalian species; prediction of lands susceptible to irrigation-induced selenium contamination of water.
