초록

토양 중 PCBs 분석방법을 검토하기 위해 우리나라 토양오염공정시험방법 및 선진국의 분석방법을 비교 검토하고 결과를 근거로, 추출 및 전처리방법, 칼럼정제방법, 분석용 칼럼 조건, 기기분석 조건 및 정량방법을 검토하였다. 또한 검토된 방법에 따라 토양 중 PCBs 세부분석지침(안)을 제시하고, 제시된 세부분석지침(안)에 의해 PCBs 제품으로 오염시킨 토양 5건 시료와 토지이용도별 및 오염원별 23건의 시료를 전처리하여 분석하였다. 기체크로마토그래피/전자포획검출법(GC/ECD)에 의한 토지이용도별 및 오염원별 PCBs 분석결과는 모든 시료에서 피크패턴(GC/ECD)을 확인 할 수 없었으나, 기체크로마토그래피/질량분석법(GC/MS)에 의한 개별이성체 정량결과는 $0.002{\sim}0.487{\mu}g/kg$ 범위로 검출되었다.
