PCB LEVELS IN THE NEIGHBORHOOD OF THE PCBs CONTAINING FACILITIES
Polychlorinated biphenyl (PCB) congeners were analyzed for 209 PCB congeners by GC/HRMS of whole environmental samples HVAS (n=60), PAS (n=34), pine needle (n=2), soil (n=1) taken surrounding the PCBs containing facility. These sampling sites are a major contributor to the environmental concentrations of PCBs and the sampling sites were categorized into five facilities (In use, Storage, Manufacture, Disposal & Clean, Recycle facility). The mean Σ209 PCB concentrations in air using HVAS and PAS were 8332.3 and 33859.0 pg m- 3. A gradient of the total PCBs in different sites using HVAS and PAS (Disposal & Clean > Recycle > Manufacture > Storage > In use > Background) was observed, suggesting the Disposal & Clean facility may be the most important source of environmental PCBs. The mean Σ209 PCB concentration in pine needle and soil were 5845.3 (pg g-1) and 1127.5 (pg g-1), respectively. And the concentrations of PCB11 was up to 0.45 - 0.53％ (air) and 13.9 - 1.6％ (pine needle and soil) of total PCBs in environmental media but only up to 0.16％ of commercial Aroclor mixtures11. This result suggests volatilization of this compound from painted surfaces of the PCBs containing equipment although the actual source of PCB11 was unknown.
