Abstract：In our work, 16 kinds of organochlorine pesticides in Pleurotus Eryngii were determined by GC-MS. Ethyl acetate was used as solvent in the experiment, and the sample of pleurotus eryngtu was extracted with acetonitrile. The limits of detection for 16 organochlorine pesticides were in the range of 0.65~19.34g/kg, and the average recoveries were in the range of 93.8%~108.9%. Meanwhile, the relative standard deviations (RSD) were obtained from 0.5% to 4.7%. The results showed that this method has simple operation, good sensitivity, reproducibility and high efficiency, which could be applied to the quantitative determination for pesticide residue in vegetables.
