摘　　要：目的建立一种同时检测7种菊酯类农药快速灵敏的分析方法。方法采用气质联用的方去,同时对蔬菜中的7种菊酯类农药进行定性及定量分析。结果该方法对7种菊酯类农药拘回收率在63.9%～105.2%之间,RSD<6%。应用本方法对15种蔬菜中菊酯类农药进行测定,阳性率为4.7%。结论该方法选择性好,分辨率高,灵敏度高,符合分析要求,具有简单、快速的特点。[ Objective ] To establish a rapid and sensitive method for simultaneous determination of 7 kinds of pyrethroid pesticides in vegetables. [ Methods ] 7 kinds of pyrethroid pesticides were qualitatively and quantitatively analyzed by GC-MS method. [ Resuits ] The recovery was 63.9% - 105.2%, RSD 〈 6%. The positive rate of detecting 15 kinds of pyrethroid pesticides in vegetables by this method was 4.7%. [ Conclusion] This method is rapid and simple, meets the requirements of analysis, with good selectivity, high resolution and high sensitivity,.
