中文摘要：本文开发了一个敏感且具有选择性的气相色谱-质谱法和优化萃取程序，用于检测胡萝卜中的农药残留，通过检测30种有机氯农药残留验证了该方法的有效性，除了顺式和反式氯氰菊酯外，所有残留检测限在0.18-0.92μg/kg范围内。应用本方法对26份胡萝卜样本进行检测，共检测出六种农药残留；
外文摘要：A sensitive and selective method was developed to determine pesticides in carrots by gas chromatography-mass spectrometry following the development of an optimized extraction procedure. The method was validated for 30 organochlorine pesticides for gas chromatography with electron capture detection obtaining limit of detection from 0.18 to 0.92 mu g/kg except for cis- and trans-permenthrin. Twenty-six carrot samples were analyzed and six pesticides were detected. The results compared with the accepted maximum residue levels in correlation to crop origin.
