| 摘 要： | 采取田间试验方法，研究了40％乐果乳油在甘蓝和土壤中的残留动态和最终残留。乐果最低检测量为0．01mg／kg，在甘蓝和土壤中最低检出质量分数为0．03mg／kg。在甘蓝和土壤中的平均回收率为90．25％-110．39％，变异系数为1．51％-5．83％，符合农药残留分析的要求。试验结果表明，乐果在甘蓝和土壤中的消解较快．其半衰期分别为2d和1．5d，药后间隔3、7、10d，乐果在甘蓝中的残留量为ND至9．6989mg／kg，土壤中的残留量为ND至0．1732mg／kg。

| Abstract: | Dissipation of 40% dimethoate EC residue in cabbage and soil was studied through GC detection. The recovery for fortified samples for the method ranged from 90.25 to 110.39% with variation coefficient of 1.51-5.83%. The final residues of dimethoate were below 9.6989 mg/kg and 0.1732 mg/kg in cabbage and soil, respectively. The half-lives of dimethoate in cabbage and soil were 2 and 1.5 d, respectively. |
