| 摘 要： | 通过质谱条件的优化，确定苹果果实中68种拟除虫菊酯类农药残留的提取和分析方法为GC-NCI-MS。在此方法下，68种农药的检出限低于6μg／kg；在0．01、0．10、0．50mg／kg3个加标水平下，样品的平均回收率为81％-114％，相对标准偏差为1．6％-15．3％。表明该方法可用于苹果果实中68种拟除虫菊酯类农药的测定。

| Abstract: | The method for simultaneous determination of 68 pyrethroid residues in apple was developed as GC -NCI- MS through optimizing mass spectrometry conditions. By this method, the detection limit of 68 pyrethroids was less than 6 μg/kg; the average recovery ranged from 81% to 114% with the relative standard deviations （RSD） as 1.6% - 15.3% at three adding levels（0.01,0. 10, 0.50 mg/kg）. The results showed that this method was suitable for simultaneous detection of the 68 ovrethroid residues in annle. |
