工业用杀螟松,由于含有一定量的S-烷基异构体,因而常在农业应用或工业制造上引起危害,而且在产品的分析上也常造成错误的结果。为此,作者对标准品杀螟松与纯S-甲基杀螟松及其混合物的体外胆碱酯酶抑制力以及此两种化合物的水解率作了比较研究。 Fenitrothion, which contains a number of S-alkyl isomers, often causes harm in agricultural applications or in industrial manufacture, and often leads to erroneous results in product analysis. To this end, the authors compared the in vitro cholinesterase inhibitory potency of the standard fenitrothion and pure S-fenitrothion and their mixtures and the hydrolysis rates of the two compounds.
