| Abstract | Total PCB residues, non-o,o'-Cl PCBs, and the most AHH-active mono-o,o'-Cl PCB congener were determined in Great Lakes fish and sediment samples. Toxic 3,3',4,4'-tetrachlorobiphenyl and 2,3,3',4,4'-pentachlorobiphenyl were detected in both fish and sediments. There appeared to be some reduction in the percentage content of the selected AHH-active congeners in fish and sediment PCB residues when compared to their percentage content in the Aroclor mixtures suspected as sources of contamination. The TCDD equivalents (AHH induction potency normalized to TCDD, times residue concentration in pg/g) were as high as 666 pg/g in fish; PCB residues in one sediment sample appeared to have undergone reductive dechlorination by anaerobic microorganisms. |
