| 摘 要： | 采用气质联用仪，以生菜为基质，建立了蔬菜上常用及已被禁止使用的27种农药残留快速扫描方法。27种农药回收率在66．47％-130．08％之间，相对标准偏差在1．30％-25．68％之间，方法的最低检出限在0．0001—0．0594mg／kg之间。并应用所建立的方法研究了13种农药在生菜上喷施后的残留情况，为同时研究多种农药在同一作物上的代谢情况及各农药喷施后的安全间隔期提供依据。

| Abstract: | A method for measuring simultaneously the residues as many as 27 pesticides, which are in common use or forbidden in lettuce, by GC-MSD has been developed. The recoveries were obtained between 66.47 and 130.08% with relative standard deviations between 1.30 and 25.68%. The degradation of 13 pesticides in the 27 was studied by the method developed. This research provides the safe intervals of the pesticide and a potential method for the study of multi-residue degradation on a plant simultaneously. |
