초록
본 연구에서는 잔류성유기오염물질(POPs) 관련 스톡홀름협약에 효율적으로 대응하고 POPs 물질의 잠재적 위험으로부터 국민 건강과 생태계를 보존하기 위해, '09년 신규 POPs 물질로 협약에 등재된 9종의 물질 중 우선적으로 POPs 공정시험방법 마련이 필요한 chlordecone, endosulfan, hexachlorocyclohexane (α-HCH, β-HCH, γ-HCH) 5종의 분석방법 확립 및 환경시료의 적용성 평가를 통해 POPs 공정시험방법을 마련하였다. 신규 POPs 5종은 모두 유기염소계 농약류(OCPs)로 기존 유기염소계 농약류의다성분 동시분석방법에 추가하여 시험방법을 검토한 결과, 전처리과정에서 플로리실컬럼 및 활성탄컬럼정제를 통해 본 연구에서 검토한 신규 POPs 5종 중 α-HCH, β-HCH, γ-HCH 및 endosulfan에 대해서 동시전처리를 실시하여 GC/MS 및 HRGC/HRMS로 분석할 수 있는 방법을 제안하였다. 또한 chlordecone 에 대해서는 현재 GC분석으로 높은 감도를 얻을 수 없는 문제점으로 인하여, 향후 LC/MS/MS 방법을추가 검토한 후 최종 시험방법을 제시하되 이번 연구에서는 GC/MS 방법을 제시하였다.
Abstract
The purpose of this study is to set up the analytical method of new persistent organic pollutants (POPs)such as chlordecone, endosulfan, α-HCH, β-HCH, γ-HCH. The analytical methods for these compounds listed as new POPs by the Stockholm Convention need to be newly established. Therefore, we proposed the analytical method for 5 organic chlorinated pesticides (OCPs) and then applied the analytical method to environmental samples. To do this, the pre-treatment such as florisil and activated carbon cleanup process in the Korean official method for classic POPs had been reviewed. All of compounds except chlordecone were pre-treated simultaneously with reviewed cleanup process and detected by GC/MS and HRGC/HRMS respectively. There is a problem that chlordecone could not get a high sensitivity by GC analysis, but in this study GC/MS method was proposed.
