Abstract Because polychlorinated biphenyls (PCBs) in environmental or biological samples have for some time been identified and quantitated using Aroclor® mixtures to determine total PCBs, few data have been generated on individual congeners. Thus, methods were developed to allow the determination of individual congeners in various fish species of different sizes from Wisconsin waters. High resolution gas chromatography was used to separate the congeners. Established relative retention times were used for congener identification, while quantification was performed with five Aroclor® mixtures, with published values for congener weight percent composition, as standards. Among the most prominent congeners found in fish were congener numbers 153/132, 138, 66/95, 110, 180, 70/76, 146, 28/31, 149, 118, and 105. It is anticipated that information on the distribution of PCB congeners in the Great Lakes and other Wisconsin waters will be increasingly important from a toxicological standpoint, and, ultimately, for assessing the risk from PCBs to fish consumers.
