| 摘 要： | 五氟磺草胺作为苗后除草剂被广泛应用于水稻田中杂草的防除，其对水生植物、陆生植物和土壤微生物群落可能存在潜在风险，因此，对五氟磺草胺在水土环境中的转化规律与归趋开展定量研究，已受到学者们的关注。本文对五氟磺草胺在稻田水土环境中的吸附、降解以及对周围环境影响方面的研究进展进行了综述、归纳和分析。指出目前对五氟磺草胺在土壤中吸附的研究报道较少，尚未见有关其在水土环境中运移方面的研究，同时应加强其对水土环境风险评估的研究。

| Abstract: | Penoxsulam is a post-emergence triazolopyrimidine sulfonamide herbicide which is widely used for the control of annual grasses and broadleaf weeds in rice cultivation. It is suspected to pose a potential risk for aquatic and terrestrial plants as well as for soil microbial communities. Recently, more and more attention has been focused on the quantitatively study of the fate, and transformation of penoxsulam in rice field. In this review, the research progresses on adsorption and dissipation behaviors of penoxsulam in rice paddy systems were summarized and analyzed in detail. It is suggested that studies investigating penoxsulam adsorption onto soil is limited, and little research focused on the transport of penoxsulam in soil and water system has been conducted. Furthermore, the risk assessment of the effect of pesticide on soil and water environment should be strengthened. |
