农药的毒性效应及其对水生生物影响的研究进展OA

Pesticide application is an important means to control agricultural and forestry diseases,pests and weeds in modern agriculture and ensure the safety of grain production.However,a large number of pesticides that are not absorbed and utilized by plants enter the aquatic ecosystem through rainwater scouring,atmospheric wet deposition,surface runoff and other ways,posing a potential threat to the stability of the aquatic ecosystem.In this study,the application and residue status of pesticides were taken as the starting point,and the toxic mechanisms of oxidative stress,neurological dysfunction,endocrine system dysregulation,and intestinal microbial community structure destruction induced by pesticides were cen-tered on.The acute toxicity,immune response,genetics and development,neurological function and behavior,and hor-mone regulation were focused on.The research progresses of toxic effects of pesticides on aquatic organisms such as algae,aquatic invertebrates,and fishes were summarized in multiple dimensions,and the development direction and key areas of pesticide research in the future were prospected.The purpose of this study is to provide a theoretical basis for ecological risk assessment and environmental safety management of pesticides,and to reduce the potential risks of pesticides to aquatic or-ganisms and the ecological environment.
