Lake Ontario fish, water, sediment, net plankton, Cladophora, and benthos were examined for DDT group pesticides, dieldrin, and PCBs. Endrin, BHC group pesticides, and heptachlor were also identified in some fish samples. Average concentrations ranged from 28 ng/1 (t-DDT), 4.8 ng/1 (dieldrin), and 55 ng/1 (PCBs as Aroclor 1254 equivalent) for water to 1.40 micrograms/g (t-DDT), 0.07 micrograms/g (dieldrin), and 5.15 micrograms/g (PCBs) for whole fish. DDE levels were generally similar to t-DDT values. PCB/t-DDT ratios averaged 2.6 for all samples except for sediment (7.0) and benthos(5.3).
