Abstract
目的 测定金线莲中六六六(BHC)和滴滴涕的残留情况.方法 采用气相色谱法(GC)对金线莲中BHC(α-BHC、p-BHC、7-BHC、δ-BHC)、滴滴涕(PP'-DDE、PP'-DDD、OP'-DDT、PP'-DDT)8种有机氯类农药残留的限量检测.结果 BHC、滴滴涕标准工作曲线的线性良好,相关系数0.998 8~0.999 7,平均回收率95.4%~98.9%,RSD为1.00%~2.98%.检出限为0.005 3~0.021 μg/L.测定结果显示:β-BHC为0.000 9 mg/kg(其中α-BHC、γ-BHC、δ-BHC、PP'-DDE、OP'-DDT、PP'-DDD、PP'-DDT未检出).结论 该方法具有较高的灵敏度和线性范围,测定结果准确可靠,科学可行,可用于金线莲中BHC和滴滴涕农药残留的质量监控.
