Ryans, R. FATE AND EFFECTS OF POLLUTIONS ON AQUATIC ORGANISMS AND ECOSYSTEMS: PROCEEDINGS OF USA-USSR SYMPOSIUM. HELD IN ATHENS, GEORGIA ON OCTOBER 19-21, 1987. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/9-88/001 (NTIS PB88242615).
Description:
The proceedings include reports of modeling: runoff of substances from agricultural watersheds, lacustrine systems, toxic pollutant risk of aquatic organisms, and tributyltin exposure. Social and economic aspects of water quality management are examined and an integrated system for controlling water use and conservation is discussed. Effects of ammonium ions on mineral exchange in fish and ammonia distribution and excretion by fish are examined. The first use of a uniform toxicity test in both countries is described and a system for remote monitoring of ecosystems is presented. Pesticide exposure is examined through aquatic community studies and in studies of resistance mechanisms in carp and perch. Buffer capacities of freshwater ecosystems for metals is examined and the relationship of trace metal body burdens and gill damage in fish to surface water acidification form atmospheric deposition is explored.
