Abstract：
OBJECTIVE: To develop a method for determination of 20 indicator polycholorinated biphenyls in fish by GC-LRMS.
METHODS: Fish sample was added 13C lablled internal standard and cleaned-up by a multilayer silica column and a alumina column. Sample was analyzed by HRGC-LRMS using SIM mode.
RESULTS: Detection limits of 20 indicator polycholorinated biphenyls were 0.009 - 0.044 ng/g. Average recovery were 79.7% - 112.6%, RSD were 1% - 8% (n = 6).
CONCLUSIONS: Results showed that the method was suitable for determination of indicator PCB in fish sample.
