Abstract Fillets from 11 species of commercial fish from the Great Lakes were analyzed for residues of 39 polychlorinated biphenyl (PCB) congeners and 24 other organochlorine compounds. Eel and trout contained the highest amount of PCB (753 and 633 ppb wet weight, respectively) and other organochlorines (607 and 1404 ppb, respectively); perch and carp contained the lowest residues. The pentaand hexachlorinated PCBs were the major congeners in all species except whitefish, in which the tetrachlorinated congeners predominated. Toxaphene was the most abundant organochlorine pesticide in trout; p,p′ -DDE was the major component of this class in eel. Residue concentrations in commercial carp were compared with residues present in carp from a fishery closed to commercial operation. Although both PCB and organochlorine pesticide levels in carp were among the lowest for all commercial fish samples, levels from the contaminated area were among the highest.

This study shows that persistent organochlorine contaminants, including PCBs, reached higher concentrations in lamprey of the St. Lawrence River basin 40 years ago. A comparison was made of the concentrations of 22 organochlorine pesticides and 93 polychlorinated biphenyl (PCB) congeners in formalin-preserved lamprey ammocoetes collected between 1947–1950 and in 1990 in the St-François and Ste-Anne rivers, St. Lawrence River basin, Québec. Eight pesticides (β-BHC, α-Chlordane, γ-Chlordane, p,p′-DDD, o,p′-DDE, p,p′-DDE, p,p′-DDT, and Heptachlor) reached higher concentrations in the earlier period, with Mirex being the only pesticide found in higher concentrations in 1990. Seventeen PCB congeners (24(27), 28, 98(84), 101, 110(77), 128, 129, 141, 149, 151, 158, 174, 177, 180, 183, 187(182), and 198) had higher concentrations in the 1947–1950 period compared with 1990. A significant inverse relationship was found between the concentration of the various PCB congeners and sampling date. The concentrations of DDT have decreased significantly, while its metabolites, DDD and DDE, have increased significantly over the last 40 years.
