Summary: We report the results of individual polychlorinated biphenyl (PCB) congeners in the surficial freshwater sediment from a wastewater lagoon located in Virginia (USA). PCB congeners were measured using tandem mass spectrometry (GC-MS/MS) in multiple reaction monitoring mode (MRM), a method that provides a high-level selectivity and sensitivity for PCBs in complex environmental samples. The PCB concentrations (sum of 171 congeners or coeluting peaks) range from 6,340 to 12,700,000 ng/g dry weight (d.w.). PCB congener profile of samples resembles commercial mixture Aroclor 1248, with the exception of one sample.
