In the US polychlorinated biphenyls (PCBs) were produced in mixtures (Aroclors) of the 209 different PCB congeners. The Aroclors differ not only in the congeners contained in the mixture, but also in the weight percent of the congeners. Until recently almost all environmental and biological samples were analyzed for PCBs by matching the chromatographic pattern to the pattern of pure Aroclors and results were reported as an Aroclor or mixture of Aroclors. However, with the refinement of high resolution capillary gas chromatographic techniques, it is now possible to identify and quantify individual PCB congeners in environmental samples. The purpose here is to present results of analyses of river sediments for these toxic PCB congeners using a multidimensional chromatography technique.
