采用随机与定点抽样的方法采集贺州市主要蔬菜生产基地及农贸、批发市场中蔬菜样本120份，采用气相色谱和气质联谱法测定其中13种有机磷、有机氯和拟除虫菊酯类农药残留。

The factors included the type of extractant, the amount and the extraction times, the type of purified column, the type and dosage of eluviatant about the pre-treatment of the samples. The extraction was 3 minutes (13500rpm) of high speed homogenize extraction. 50mL acetonitrile as an extractant was acted on one time extraction. The florin silicon column was taken as the purified column. The extraction was eluted by 30ml 3:2 acetone - hexane and concentrated by nitrogen blowing under 50 °C water bath.The chromatographic separated conditions were studied applied the Agilent 6890 gas chromatographic apparatus and DB-17 capillary column(30m×0.25mm×0.25μm).
