Abstract |
SPME-GC/MS법을 사용하여 내분비계 교란물질로 추정되는 플라스틱 가소제류를 동시에 분석할 수 있는 방법을 고안하였다. 본 연구에서 사용한 플라스틱 가소제는 dimethyl phthalate(DMP), diethyl phthalate(DEP), dibutyl phthalate(DBP), benzylbutyl phthalate(BBP), diethylhexyl phthalate(DEHP), di-n-octyl phthalate(DnOP)이었다. 표준 시료에 대한 분석결과에서 검출한계(LOD)는 0.163~0.299 ng/ml, 상대표준편차는(%RSD)는 5.85~15.80이었다. 본 방법을 사용하여 한강, 금강, 낙동강 및 섬진강에서 채취한 시료를 분석한 결과, DBP와 DEHP 만이 4대강 모두에서 미량 검출되었으며, DBP와 DEHP의 농도는 각각 0.192~1.270 ng/ml 및 0.077~1.102 ng/ml 범위를 보였다.
A procedure based on solid phase microextraction extraction(SPME)-GC/MS has been developed for the simultaneous analysis of plasticizers. The plasticizers investigated in this study are dimethyl phthalate(DMP), diethyl phthalate(DEP), dibutyl phthalate(DBP), benzylbutyl phthalate(BBP), diethylhexyl phthalate (DEHP), di-n-octyl phthalate(DnOP). The limit of detection(LOD) was 0.163~0.299 with relative standard deciation(RSD) of 5.85~15.80% for these compounds. At water reserviors of Han, Geum, Nakdong and Sumjin rivers, only DBPand DEHP were detected at trace level, 0.192~1.270 ng/ml for DBP and 0.077~1.102 ng/ml for DEHP depending on the river.
