摘要: 毒死蜱具有杀虫活性高、杀虫谱广、害虫不易产生抗药性等特点,是当前农业生产中大量使用的一种有机磷酸酯类杀虫剂,但其残留问题以及对生态环境造成的危害也日益受到关注。为了解毒死蜱在土壤中的降解转化过程及残留分析方法,本研究介绍了毒死蜱的基本性质、作用机制与应用现状,总结了它在土壤中的降解产物、降解机理以及影响降解的主要因素,概述了其在土壤介质中的提取、净化、分析原理和方法,并对其残留降解和检测技术今后的研究方向进行了展望。笔者认为未来应进一步加强毒死蜱在土壤-水-植物-大气复杂环境系统中的降解研究,发展能够将高效的样品前处理和灵敏的后续检测集于一体的快速分析技术。

Abstract: Chlorpyrifos was one of the most widely used organophosphorus insecticides in agriculture due to its characteristics of excellent insecticidal activity, broad spectrum and difficult resistance to insects. However, great concern had been raised regarding its residue problems and harmfulness to ecological environment. To understand the degradation process and residue analytical methods of chlorpyrifos in soil, the basic properties, action mechanism and current applications of chlorpyrifos were introduced in this paper, and its metabolites, degradation mechanism and dominant factors affecting degradation in soil were described as well. Additionally, extraction, purification, analytical principles and methods of chlorpyrifos in soil were summarized. At last, future research directions on degradation and detection techniques of chlorpyrifos were proposed. The authors suggested that further studies are needed on the degradation of chlorpyrifos in complex environment system soil-water-plant-atmosphere in the future and should develop rapid detection techniques combining efficient sample pretreatment and sensitive subsequent detection.
