4、(30m×0.25mm×0.25μm)毛细管柱的GC-MS定性定量测定。结果二嗪农、阿特拉津、扑草净、丁草胺、联苯菊酯在4~80μg/L浓度范围内,甲拌磷、2,4-D丁酯、甲基对硫磷、马拉硫磷、氯丹、甲氰菊酯在10~200μg/L浓度范围内,α-硫丹、β-硫丹、三氟氯氰菊酯在20~400μg/L浓度范围内,乐果在40~800μg/L浓度范围内,具有2良好的线性响应,相关系数(r)在0.998~1.000之间,各待测物的方法加标回收率为51.3%~113.1%,方法的检出限为0.05~1.00μg/L,方法的定
5、量限为0.20~3.00μg/L,批内精密度在3.17%~22.79%,批间精密度在5.58%~26.13%。结论该方法适用于血液样品中15种农药的含量检测。关键词:有机磷有机氯拟除虫菊酯除草剂气相色谱-质谱法中图分类号:R595.4R994.6O657.63文献标识码:ADeterminationof15kindsofpesticidesinbloodbygaschromatography-massspectrometryPANXingfu,DUHuifang,YANHuifangChineseCenter
