Organochlorine Pesticides and Polychlorinated Biphenyls (PCBs) in Sediments and Biota From Four US Arctic Lakes
Organochlorine (OC) concentrations in surface sediment, snails (Lymnea sp.), and two freshwater fish species (grayling, Thymallus arcticus; and lake trout, Salvelinus namaycush) from four lakes in the US Arctic were determined. In surface sediment, chlorinated benzenes (including hexachlorobenzene,...
