Objective To establish a method to detect the residual indicator polychlorinated biphenyls(PCBs) in the flesh of fish by gas chromatography using acid digestion. Methods The sample was digested by H2SO4, then extracted by N-hexane and methylene chloride(50:50, v:v) and cleaned up by H2SO4, after that determined by capillary gas chromatography. Results PCBs reference material GBW(E)100131 in Cod was detected by this method and the result was in accordance with the assigned value. The recovery was 93.7%~104.4%, RSD was 2.75%~4.65%(n=6), and the detection limit was 0.22~0.44 μg/kg. Conclusion The method is simple, rapid, sensitive, accurate and precise, and it can be used for the determination of indicator polychlorinated biphenyls in the flesh of fish.
