A gas chromatography-mass spectrometry(GC-MS)method was developed for the simultaneous determination of residues of six insecticides in soil samples:sclerotinide,isomylurea,acetamidine,cyhalothrin,indocarb and deltamethrin.All the six insecticides had good correlation in the linear range of 2.00～100 µg·L-1,with correlation coefficients greater than 0.995,detection limits ranging from 0.006 to 0.021 mg·kg-1,sample recoveries ranging from 88.3％to 104.8％,and relative standard deviations less than 5％.The method has the advantages of simple pretreatment,high sensitivity and accurate test results,and is suitable for the detection of pesticide residues in soil samples.
