Chiral pesticides account for about 40% of the total pesticides. In the process of using pesticides, it will inevitably flow into the surface water and even penetrate into the groundwater through surface runoff and other means, as a consequence, it affects the water environment. Although the enantiomers of chiral pesticides have the same physical and chemical properties, their distribution, ratio, metabolism, toxicity, etc. in the organism are often different, and sometimes even show completely opposite biological activities. In this article, the selective fate of different types of chiral pesticides such as organochlorine, organophosphorus, triazole, pyrethroid and other chiral pesticides in natural water bodies and sediments, acute toxicity to aquatic organisms, chronic toxicity and other aspects are summarized to further reflect the risks between the enantiomers of chiral pesticides to non-target organisms in the water environment. In this review, we hope to further explore its harm to human society through the study of the toxicity of chiral pesticide enantiomers, so as to provide data support and theoretical basis for the development and production of biochemical pesticides.
手性农药约占农药总量的40%。在农药使用过程中，不可避免地会流入地表水，甚至通过地表径流等方式渗入地下水，进而影响水环境。虽然手性农药的对映体具有相同的理化性质，但其在生物体中的分布、比例、代谢、毒性等往往不同，有时甚至表现出完全相反的生物活性。本文综述了有机氯、有机磷、三唑、拟除虫菊酯等不同类型手性农药在天然水体和沉积物中的选择性归趋、对水生生物的急性毒性、慢性毒性等方面，以进一步反映手性农药对映体对水环境中非靶标生物的风险。在本综述中，我们希望通过研究手性农药对映体的毒性，进一步探索其对人类社会的危害，为生化农药的开发生产提供数据支持和理论依据。
