Abstract

This study was performed to improve the analytical methods and re-establish the regulatory standard of PCBs-containing solid wastes for sufficient management in which has been concerned internationally. To do this, the sampling, pre-treatment and quantification methods which were used in USA and Japan were discussed. It was thought properly that new standard of PCBs-containing solid wastes was established through correlation with PCBs concentration of transformer oil. The surface wipe sampling was selected in the nonporous materials and cutting sampling in the porous materials. In the absence of transformer oils, electrical equipment is PCB-contaminated if it has PCBs at ${\geq}0.4{\mu}g/100cm^2$ as measured by a wipe test of a nonporous surface and if it has at 0.04 mg/L as measured by cutting test of a porous material. Also, new analytical methods for PCBs containing solid waste were proposed.

본 연구에서는 PCBs 함유 고상폐기물의 효율적 관리를 위해 현행 폐기물 공정시험방법의 용출 시험방법을 고상폐기물 종류별 표면채취법, 부재시험방법, 세정시험방법 등의 함량시험방법과 비교검토하여 PCBs 함유 고상폐기물의 시험방법(안) 및 기준(안)을 마련하였다. 우리나라의 표면채취법에 의한 비함침성 고상폐기물의 규제기준은 미국 및 일본과 같은 수준으로 각 국의 액상폐기물인 절연유 기준과 표면채취법에 의한 처리기준의 수치적 관계를 이용하여 산출하는 것이 타당한 것으로 판단되어진다. 이에 PCBs 함유 고상폐기물 중 규소강판 등 표면채취가 가능한 평면형 비함침성 부재는 표면채취법으로 시료를 채취하여 함량분석법으로 분석하는 경우, 비함침성 고상폐기물의 규제기준(안)을 $0.4 {\mu}g/100cm^2$으로 설정하였다. 또한, 표면채취가 어려운 시료를 일정한 크기로 잘라 부재를 채취한 후 함량분석법으로 분석하는 경우에는 규제기준을 0.04 mg/kg을 제안하였다.
