Method 8080, as published in the Second Edition of Test Methods for Evaluating Solid Waste, EPA Manual SW-845, has been evaluated in a single-laboratory study. The Florisil procedure recommended in Method 8080 for sample cleanup does not separate organochlorine pesticides (OCPs) from the polychlorinated biphenyls (PCBs). Consequently, gas chromatographic analysis of OCPs on the packed column recommended in the method may result in false identifications or in no identifications at all when PCBs are present. Therefore, silica gel was substituted for Florisil, a capillary column was substituted for the packed column, and a sulfur cleanup procedure was incorporated in the method. The revised method was evaluated with samples spiked at 3 concentrations. Precision and accuracy indicate that the revised method can be reliably applied to the determination of OCPs and PCBs in liquid and solid matrices. Detection limits for liquid matrices range from 0.02 to 0.09 ..mu..g/L for OCPs and from 0.5 to 0.9 ..mu..g/L for PCBs. Detection limits for solid matrices range from 1 to 6 ..mu..g/kg for OCPs and from 60 to 70 ..mu../kg for PCBs.
