摘　　要：目的：建立水中农药残留量的气相色谱-质谱联用的分析方法。方法：样品经有机溶剂提取、经氮吹浓缩后定容，采用气相色谱-质谱法定性定量。结果：30种常见农药组分检出限均小于0.02mg／L，相关系数均大于0．995。加标回收率为84．9％～110％，相对标准偏差小于10％。结论：本方法能够快速地检测饮用水中30种农药残留，干扰少，定性准确，结果可靠，具有实用性。Objective： To establish a method for determination of 30 pesticide residues in water using gas chromatography with tandem mass spectrometry. Methods： The pesticides were extracted from the water samples with organic solvent and determined using gas chromatography - mass spectrometry qualitatively and quantitatively. Results： Detection limit of 30 common pesticides were less than 0.02 mg/L, The correlation coefficient were all over 0. 995, and the recoveries ranged from 84.9% to 110% , Relative standard deviations （RSDs） were all less than 10%. Conclusion： This method is rapid and less interferential with high accuracy, reliability and applicability.
