초록

한국과 일본의 환경대기 시료를 대상으로 PCB 전이성질체 분석을 통하여, 오염정도 및 이성질체 분포 특성을 파악하고 통계적 처리기법을 통하여 발생원을 추정하였다. 환경대기 중 PCB 농도는 한국이 $0.003{\sim}1.01\;pgTEQ/m^3$ (평균 $0.22\;pgTEQ/m^3$), 일본이 $0.002{\sim}0.014\;pgTEQ/m^3$(평균 $0.007\;pgTEQ/m^3$)으로 나타났다. 한국의 환경대기 중 PCB 농도는 공단지역이 도시지역간의 농도 변화폭이 매우 크게 나타났다. 이성질체 분포에 있어서는 대체로 유사한 경향을 나타내었으나 한국의 공단 지역에서는 $7{\sim}10CB$의 고염소화 동족체가 검출되어 특정한 오염원이 존재할 가능성이 시사되었다. 주성분 분석을 통하여 한국과 일본의 환경대기 중 PCB 오염원을 추정한 결과 한국 환경대기 시료가 일본 환경대기 시료에 비하여 소각로 영향을 많이 받고 있으며 PCB 제품 영향은 일본에 비해 상대적으로 적은 것으로 판단된다.

This study was conducted to investigate the level of PCBs and distribution of PCB congeners in the ambient air of Korea and Japan. The source of PCBs were also studied by a statistical method. The TEQ concentration of PCB in the ambient air of Korea and Japan were between 0.003 and $1.01\;pgTEQ/m^3$(mean value : $0.22\;pgTEQ/m^3$) and between 0.002 and $0.014\;pgTEQ/m^3$ (mean value: $0.007\;pgTEQ/m^3$), respectively. The ambient air of industrial area of Korea showed a fluctuation in PCB concentration than other sampling area. The isomer distribution patterns in the ambient air was more or less similar in all sampling places. In addition, highly chlorinated homologues ($7{\sim}10CB$) were detected in the only Korea industrial area. This observation suggests that there is a possibility of specific source of PCBs in the industrial area. The source identification of PCB in ambient air was performed using multivariate statistical analysis(principal component analysis). As a result, it is estimated that the Korean ambient air was more influenced by combustion process than the ambient air of Japan and also the effect of PCB commercial products was relatively a small.
