Polychlorinated biphenyls in solid waste and solid-waste-related materials
Municipal refuse along with various solid-waste processing samples were analyzed for polychlorinated biphenyls (PCBs). In all cases, the samples required drying, particle-size reduction, separation of extraneous material, and extraction with an organic solvent. The extracts were cleaned-up by chromatography and analyzed by gas chromatography. The qualitative results obtained indicate that PCBs were present in several of the samples analyzed. These results are consistent with findings, by other investigators, that there is PCB contamination in many parts of the environment and they indicate that disposal of solid waste contributes to this contamination.
