甲氧基丙烯酸酯类农药生态毒理及其微生物降解研究进展

摘要

近年来,随着甲氧基丙烯酸酯类农药用量的不断增加,其产生的农药残留污染问题已引起社会的广泛关注.如何有效治理甲氧基丙烯酸酯类农药的残留污染是科研工作者亟待解决的问题.生物修复技术以其高效、廉价、安全等优点,已成为消除农药残留污染的有效措施.综述了甲氧基丙烯酸酯类农药的生态毒理及其微生物降解的研究现状,介绍该类农药代谢产物及基本降解途径,分析甲氧基丙烯酸酯类农药残留污染微生物降解存在的问题并提出发展方向,为解决该类农药残留污染危害提供技术参考.%The widely used strobilurin fungicides in agriculture have become a public concern because of their heavily environmental contamination and toxic effects on mammals. Such concerns,therefore,highlight the critical need for effective and advanced remediation technologies for the removal of strobilurin residues. Recently,bioremediation has emerged as a great potential alternative to eliminate pesticide residues because of its effective,low-priced,and eco-friendly properties. In this review,we summarized the research status of ecotoxicity of strobilurins and their microbial degradation. The main metabolites and the proposed degradation pathways of strobilurins were investigated. Moreover,the deficiencies of microbial degradation and the future development were discussed. These results may lay a solid foundation for developing new and safe measures for solving pollution hazard from strobilurin-like residues.
