Polychlorinated Dioxins and -Furans in Lake Roosevelt (Columbia River) sportfish, 1990

In June 1990, as part of Ecology's investigation of contaminants in Lake Roosevelt, a series of sediment and bottom fish samples were collected from Lake Roosevelt and vicinity for analysis of PCDDs and PCDFs. Six sites in Lake Roosevelt between the international border and Grand Coulee Dam were sampled for dioxins and furans, PCBs and pesticides, additional organic compounds and mercury. The results of these and other PCDD/PCDF analyses on Lake Roosevelt samples have been reported elsewhere (Johnson et al. 1991a,b). The report that serves as the source of the additional analytical data contains results of analysis of sediment and bottom fish samples for 44 additional xenobiotic compounds (Johnson 1991).
