摘　　要：建立了采用QuEChERS-高效液相色谱法(QuEChERS-HPLC)测定蔬菜水果中残留的氨基甲酸酯类和苯甲酰脲类农药的检测方法.农药组份回收率在70.5%~118.5%之间,相对标准偏差(RSD)在2.6%~9.8%之间,方法的检出限为0.02~0.30 mg/kg,满足国标检测限量要求.该方法具有快速、简便、经济、环保的特点,便于在地方检测机构推广.A QuEChERS high performance liquid chromatography（ HPLC） method for the determination of carbamate and benzoylurea pesticides in vegetables and fruits was established. The recovery rate of pesticide components is between 70. 5% and 118.5%,and the relative standard deviation（RSD） is between 2. 6% and 9. 8%. The detection limit is between 0. 02 - 0. 30 mg/kg,meeting the requirements of the national standard for the detection limit. The developed method is rapid,simple,economical and environment-friendly,and is easy to be popularized in local inspection institutions.
