啶氧菌酯环境归趋与生态风险研究进展

Research Progress on the Environmental Fate and Ecological Risk of Picoxystrobin

啶氧菌酯是一种对生态系统存在安全风险的甲氧基丙烯酸酯类杀菌剂,从环境归趋,生态毒理的角度出发,综述了啶氧菌酯在土壤、水中、农作物中的归趋,阐述了啶氧菌酯对蚯蚓、蜜蜂和水生非靶标生物急/慢性毒性,和对组织、酶活、蛋白、基因等方面的影响进行了归纳,并讨论了啶氧菌酯未来的生态毒理学研究方向。以期为进一步研究啶氧菌酯对非靶标生物毒性效应和作用机理,并制定相关策略以减少其生态风险提供依据。

Picoxystrobin is a kind of methoxyacrylate fungicide with safety risks for the ecosystem.This study reviewed the fate of picoxystrobin in soil,water,and crops from the perspective of environmental fate,ecotoxicology,described the acute/chronic toxicity of picoxystrobin for earthworms,bees,and aquatic organisms,and generalized the effects on tissues,enzyme activity,proteins,and genes,and discussed the future ecotoxicological research directions of picoxystrobin.The ecotoxicological directions of apicoxystrobin are discussed to provide a basis for further studies on the toxic effects and mechanisms of action of picoxystrobin on non-target organisms and to develop strategies to reduce its ecological risks.
