有机磷农药是烟草生产上防治烟蚜和烟青虫等主要害虫常用的一类农药。乐果、马拉硫磷、敌敌畏和甲基对硫磷等自60年代以来就广泛应用于烟草生产。本文所列13种有机磷农药均在烟草上有过试验或应用。以前,烟草的农药残留研究都是针对特定的农药品种逐一进行的,国内尚少见用一种方法一次检测同一类农药残留的报道。然而,这后一种方法具有快速、简便、经济、准确的优点,可实现同类多品种农药的快速分析。本文以有机磷农药的13个品种为材料,介绍其在烟草中多残留的气相色谱法测定结果。
Organophosphorus pesticides are a kind of common pesticides used to control major pests such as tobacco aphid and tobacco budworm in tobacco production. Dimethoate, malathion, dichlorvos and methyl parathion have been widely used in tobacco production since the 1960s. Thirteen kinds of organophosphorus pesticides listed in this article have been tested on tobacco or application. Previously, the research on pesticide residues in tobacco was carried out one by one for specific pesticide varieties. However, it is seldom reported in China that using one method to test the same kind of pesticide residue at a time. However, this latter method has the advantages of being quick, easy, economical and accurate, enabling rapid analysis of the same multi-species pesticides. In this paper, 13 varieties of organophosphorus pesticides as materials, introduce their residues in tobacco by gas chromatography results.
