摘要：An method for determination of organochlorine pesticides(OCPs) and polychlorinated biphenyls(PCBs) in sediments was established by using accelerated solvent extraction(ASE),followed by GPC clean up and gas chromatography mass spectrometry. The results demonstrated that the linear is good in the 5.00 μg/L~200 μg/L, recovery was tested by addition of the mixed standards at two different concentration levels, and the results of recovery were found in the range of 70.8%～121%, the relative standard deviation(RSD) were ranged from 2.7% to 11.5%. Detection limits of the method for OCPs and PCBs were in the range of 0.03 μg/kg～0.37 μg/kg. Actual samples were measured by current method, and the results showed that PCBs were not detected in the 12 sediment samples, but OCPs were detected in 9 of these samples.
