鱼塘水中除草剂检验三例

Determination of Herbicides In Fish Pond by GC/MS

建立了鱼塘水中除草剂成分的GC/MS检验方法。鱼塘水经SPE前处理后,进行GC/MS分析,从3起该类案件检材中检测出扑草净、莠去津和莠灭净成分。该方法简单易行,灵敏度高,结果准确,对办理鱼塘投毒案件具有重大意义。

A method for determining herbicides in fish pond water was established.Samples were extracted by using solid phrase extraction （SPE） and then detected by GC/MS. Prometryn, atrazine and ametryne atrazine in samples were deter- mined from 3 cases.The method is simple, sensitive and accurate, it can be used for rapid detection in casework.
