Abstract: A new method for the rapid determination of 15 pesticides residue in vegetables by Gas chromatography/Massspectrometry was developed. The analysis time decreased by optimize the operation conditions. The result has more credibilitywhen determine the nature by retain time and the proportion of characteristic ions. The average spiked recoveries ranged from77% to 110%,with the relative standard deviations(RSD) from 5% to 21%.

Key words: gas chromatography, mass spectrometry, vegetables, pesticides residue
