Book excerpt: A survey of polychlorinated biphenyls (PCBs) in industrial effluents and process streams in Canada was conducted in two phases. Phase 1 was an overall screening study with samples taken .from various industrial sectors, while in Phase II only those industrial plants identified in Phase I as discharging significant quantities of PCBs in their effluents were sampled. In Phase I, a total of 308 samples were collected and analyzed for PCB concentration. Of the 308 sample tested, 48 were found to contain more than 0.1 ppb of PCBs. Industries .identified as having sarnples containing PCBs were: 1) those using PCBs in their product's, 2) those using PCB-containing materials in the operation of equipment, and 3) those using recycled materials contaminated with PCBs in their processes. Samples containing PCBs were also obtained from a number of other industrial facilities and from sewage treatment plants. The Phase Il study included sampling a total of 45 effluents from seven selected plants. The results confirmed the findings of the Phase 1study. The sources of PCB contamination and .the formation .of PCBs as inadvertent by-products of various operations are discussed.
