Individual polychlorinated biphenyls (PCBs) in surficial urban soil from East Chicago, Indiana, USA, were measured and reported here from thirty-three sites. Gas chromatography (GC) in tandem with Mass Spectrometry GC-MS/MS (Agilent 7000) in multiple reaction monitoring (MRM) mode was used to quantify all 209 congeners in 171 individual or coeluting congener peaks. The GC was equipped with a Supelco SBP-Octyl capillary column (30 m × 0.25 mm ID, 0.25 mm film thicknesses) with helium as carrier gas.

Individual PCB congener in surficial sediment using GC-MS/MS: Values = 0 indicates non-detected No limit of quantification (LOQ) correction was performed
