建立了用一种前处理方法同时检测大黄鱼中多种有机氯、拟除虫菊酯和有机磷农药残留量的分析方法。试样经乙腈水提取,离心分层后用中性氧化铝填料和ENVI-18柱净化,然后用GC-μECD和GC-FPD测定,外标法定量。14种农药在0.01～0.5 mg/L范围内线性良好,相关系数r〉0.999,样品添加量为0.001～0.01 mg/kg时回收率为63%～110%,相对标准偏差不大于10.5%,α硫丹、β硫丹、硫丹硫酸盐的定量下限（S/N≥10）为0.001 mg/kg,其余农药的定量下限均小于0.01 mg/kg。该方法准确、简便,可满足大黄鱼中多种农药残留的检测要求。

A method for multi-residues detection of organochlorine,pyrethroid,and organophosphorus pesticide residues in Pseudosciaena crocea with one pretreatment method was investigated in this study.Sample was extracted with acetonitrile-water,separated with liquid-liquid partition.It was cleaned up with neutral aluminum oxide packing and ENVI-18 column.And it was determined by GC-μECD and GC-FPD,using external standard.Calibration curves of 14 pesticides were linear between 0.01 mg/L and 0.5 mg/L,with correlation coefficients of more than 0.999.Recoveries of the pesticides were in the range of 63%～110% with relative standard deviations of no more than 10.5% in a spiked concentration range of 0.001～0.01 mg/kg.The quantification limits of the method（S/N≥10） for α-Endosulfan,β-Endosulfan and Endosulfan-Sulfate were 0.001 mg/kg,while those for the other pesticides were less than 0.01 mg/ kg.The method was accurate and simple.The method can meet the requirement of the determination of various pesticide residues in Pseudosciaena crocea.
