中文摘要：本文利用液相色谱-串联质谱技术构建了一种快速、同时检测果蔬农药残留的方法，该方法采用固相萃取技术与QuEChERS (STQ法)法联用制备检测液，采用乙腈在均质机中进行农药残留提取，然后同时进行盐析和脱水，最后采用C18和PSA微型柱对乙腈层进行提纯。根据日本卫生、劳动和福利部规定的验证方法指南，本文通过对14种果蔬中浓度在0.01μg /g以下的130种农药残留的检测评价该方法的效率。结果显示，检测出了75-120种农药残留，因此，该方法可有效应用于快速、同时检测多种果蔬中的多种农药残留。
外文摘要：A validation study was carried out on a rapid method for the simultaneous determination of pesticide residues in vegetables and fruits by LC-MS/MS. reparation of the test solution was performed by a solid-phase extraction technique with QuEChERS (STQ method). Pesticide residues were extracted with acetonitrile using a homogenizer, followed by salting-out and dehydration at the same time. The acetonitrile layer was purified with C18 and PSA mini-columns. The method was assessed for 130 pesticide residues in 14 kinds of vegetables and fruits at the concentration level of 0.01 mu g/g according to the method validation guideline of the Ministry of Health, Labour and Welfare of Japan. As a result 75 to 120 pesticide residues were determined satisfactorily in the tested samples. Thus, this method could be useful for a rapid and simultaneous determination of multi class pesticide residues in various vegetables and fruits.
