Abstract

This Analysis was conducted for 13 toxic-PCBs having TEF value among 209 PCBs isomers in sediment by isotope dilution HRGC/HRMS method. From the result, the recovery of surrogate standard was in the range of 71~99%. The concentration range for 13 toxic-PCBs in sediment was found to be 0.84~2.49 ng/g, among them the concentration levels of 2,2',3,3',4,4',5-HpCB(IUPAC No. 170) and 2,2',3,4,4',5,5'-HpCB(IUPAC No. 180) represented almost 50% of total concentrarion and that of 2,3,4,4,5-PeCB(IUPAC No. 114) showed over 10%. The TEQ concentration levelwas in the range of 0.38~2.63 pg-TEQ/g and 3,3',4,4',5-PeCB(IUPAC No. 126) concentration represented over 50% of total TEQ concentration.

본 연구에서는 209종의 PCBs 이성체중 독성등가계수(Toxic Equivalance Factor, TEF)가 제시된 13종의 toxic-PCBs에 대하여 Isotope dilution HRCC/HRMS 방법으로 저니토중의 toxic-PCBs를 분석하였다. 분석결과 surrogate 표준물질의 회수율은 71~99%로 양호하였다. 13종의 toxic-PCBs 농도는 0.84~2.49 ng/g 범위이었으며, 이중 2,2',3,3',4,4',5-HpCB(IUPAC No. 170) 및 2,2',3,4,4',5,5'-HpCB(IUPAC No. 180) 농도가 전체 농도의 50% 정도를 나타내었으며, 2,3,4,4,5-PeCB(IUPAC No. 114)도 10% 정도를 나타내었다. 독성등가계수로 환산한 농도는 0.38~2.63 pg-TEQ/g 범위이었으며, 3,3',4,4',5-PeCB(lUPAC No. 126)가 전체의 50%를 나타내었다.
