摘要:
噻虫嗪是当前全球销售量最大的新烟碱类农药之一,随着噻虫嗪的广泛使用,噻虫嗪在土壤环境中的迁移转化和归宿问题成为研究热点。本文总结了噻虫嗪对陆生生物(蜜蜂、蚕、蚯蚓、鹌鹑)、水生生物(藻类、大型溞、斑马鱼等)以及土壤微生物的影响,系统综述了噻虫嗪在农田土壤中的残留、降解、吸附解析以及迁移与淋溶等环境行为及主要影响因素,并指出了噻虫嗪在农田土壤中环境行为相关研究存在的不足以及未来研究应该关注的重点和方向,以期为噻虫嗪的科学安全使用以及保障农田土壤生态环境健康提供科学依据。

Abstract:
Thiamethoxam is one of the most widely sold new nicotine pesticides in the world. With the widespread use of thiamethoxam, the migration and transformation of thiamethoxam in the soil environment and its fate have become a research hotspot. This article summarizes the effects of thiamethoxam on terrestrial organisms (bees, silkworms, earthworms, quails), aquatic organisms (algae, large maggots, zebrafish, etc.) and soil microorganisms, and systematically reviews the residues of thiamethoxam in farmland soils. Environmental behaviors and main influencing factors such as biodegradation, degradation, adsorption analysis, migration and leaching, and pointed out the deficiencies of related research on environmental behaviors of thiamethoxam in farmland soils, as well as the focus and direction of future research, with a view to thiamethoxam Provide scientific basis for the safe and safe use of agriculture and the protection of farmland soil ecological environment.
Key words:  thiamethoxam  biological toxicity  soil  residue  adsorption  leaching
