The separation and analysis of the constituents of industrially produced polychlorinated biphenyls (PCBs) has been almost exclusively performed using techniques involving packed gas chromatographic columns. However, the packed column chromatograms proved to be inadequate with regard to the separation of the many congeners which compose the complex PCB mixtures. Unlike the packed column methods, a separation technique based upon gas capillary technology produces chromatograms with sharp peaks, and hence accurate analysis is possible according to individual congener concentrations. This capability permitted more precise analysis of macroinvertebrates - specifically aquatic insects in the polluted water of the upper Hudson River. This study examines the presence and relative concentration of 74 congeners in water and caddisfly larvae collected from 3 sites in the Hudson River. Caddisfly larvae (Insecta:Trichoptera) usually dominate the macroinvertebrate communities in riffle habitats of the study area. Their relatively large size and abundance facilitated the acquisition of sufficient biomass for analysis (200 mg wet weight). The sampling was carried out on July 6, 1983 and August 15, 1983.
