5203 |a"Concentrations of Hg, Cd, Cu, Pb, Zn and several other metals were measured in muscles and livers of fish from the Columbia River between the Hugh Keenleyside Dam and the International Boundary. Metal concentrations were evaluated in relation to guidelines for edible fish flesh and by comparison with levels in fish from other areas. Attempts were made to detect temporal trends in metal levels in fish tissues and to compare levels above and below the major known metal input, the effluent from Cominco Ltd. at Trail, British Columbia. … Concentrations of hepatic metallothionein in rainbow trout (Salmo gairdneri) were measured to provide an index of the effect of environmental metal levels on the fish. … Recommendations for a program of monitoring metals in Columbia River fish are made"--Abstract, pages iv-v.
