中毒污染事件中常见农药、鼠药及其他化学品的现场快速样品处理及GC-MS定性\半定量检测程序

The procedure about determination of pesticide,raticide and other chemicals in poisoning and contaminative events by GC-MS in site

目的:为快速响应食物中毒、环境污染等突发公共卫生事件,建立中毒污染事件中常见农药、鼠药和其他有毒化学品的现场快速样品处理及GC-MS定性\半定量检测程序。方法:用多种有机溶剂同时提取食物中毒、环境污染样品中常见农药、鼠药,气相色谱-质谱联用仪(GC-MS)定性\半定量快速检测。结果:运用该程序,可实现食物中毒、环境污染样品中有机磷、有机氯、氨基甲酸酯、拟除虫菊酯、鼠药及其他有毒化学品等在到达事发现场后2～3个小时内快速检测。结论:本方法原理可靠,样品处理与检测时间周期短,覆盖毒物范围广,结果准确度高,适用于突发食物中毒、环境污染样品的现场快速检测。

Objective：In order to response burst public health events,we have established a procedure to determine of pesticide and raticide in poisoning and contaminative events qualitatively and semiquantitatively by GC-MS.Methods：We extract target compounds with multiple organic solvents continuously,then extracts were determined by by GC-MS.Results：Using the procedure,organophosphorus pesticides,organo-chlorine pesticides,carbamate esters,pyrethroids and raticides can be determined within two or three hours.Conclusion：The method is reliable,exact and suitable for treatment and detect food poisoning as well as environmental pollusion samples in site.
