FINAL REPORT: EXPEDITED FIELD SURVEY & SAMPLING TECHNIQUES FOR POLYCHLORINATED BIPHENYL (PCB) CONGENERS AND DIOXINS. Glen P. Jackson, Mengliang Zhang, Jen Bowman, Natalie Kruse, Dina Lopez Dec 14, 2012

ABSTRACT: This procedure describes a method for the on‐site field analysis of polychlorinated biphenyls (PCBs) in soil samples. The method describes how a measured mass of soil sample is first treated with a mixture of potassium permanganate (KMnO4) and sulfuric acid (H2SO4) before extraction of the PCBs using headspace SPME at elevated temperature (90C). The extracted PCBs are then desorbed from the SPME fiber into the inlet of a portable GC‐TMS system equipped with low thermal mass (LTM) GC column. The resulting chromatographic and mass spectrometry data is manually interpreted to determine the presences of Aroclors or PCB congeners. The total sample preparation and analysis time is less than 45 minutes. Strengths: o Allows on‐site PCB determinations in soil o Small samples required (10 g) o
