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.
