Abstract
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.
