A method that is convenient and quick,accurate and stable,suitable for quantitative detection of polychlorinated biphenyls(PCBs) in aquatic products was established. There are 7 kinds of polychlorinated biphenyls(PCBs) were detected by GC-ECD. The detection limites of this method were 0.0003 mg/kg, the line arranges of the 7 pesticides were from 0.01~1.0 μg/mL with the regression coefficient(r) of 0.99986~1.00000. At 0.05 μg/mL, 0.2 μg/mL, 1.0 μg/mL three levels, the average recoveries and Relative standard deviations(RSD) of the 7 kinds pesticide were 82.18%~96.88% and 2.4%~4.4% respectively.
