초록
미국 환경청이 지정한 129종의 priority pollutants 중 16종의 유기살충제를 포함한 토양시료를 제조하여 표준분석방법인 기체크로마토그래프-전자포획법과 기체크로마토그래프/질량분석기-SIM (selected ion monitoring)법을 이용하여 동시분석의 효율성을 실험하였다. 토양시료의 추출 및 농축방법으로는 EPA의 SW-846 방법을 조금 수정한 초음파추출법(sonication extraction)과 Soxhlet 추출법(Soxhlet extraction)을 비교 연구하였다. 각 화합물의 회수율, 상대표준편차 및 method detection limit를 측정하여 그 결과들을 보고하였다.
The simultaneous analysis of 16 organic pesticides, which are listed as a part of 129 priority pollutants by EPA(Environmental Protection Agency), was performed by GC-ECD(electron capture detector) and GC/MS-SIM(selected ion monitoring). Two extraction procedures from SW-846, sonication extraction and Soxhlet extraction, were somewhat modified and compared as an extraction and concentration method for the analysis of priority pollutants in soil. Accuracy and precision of the methods were reported from the calculation of mean recovery, mean relative standard deviation, and method detection limit.
