摘要
草甘膦在土壤中极易被吸附,代谢速度相对缓慢,在高剂量多年连续施用的情况下,其残余水平可能会逐年升高。我国是除草剂草甘膦的生产和使用大国,当前草甘膦环境残余水平及其生态效应的研究尚处于起步阶段,土壤环境草甘膦痕量残余检测的标准方法还未建立。跟进草甘膦环境行为及其生态风险评估研究,优化除草剂使用管理策略,对我国环境生态安全建设具有重要意义。本文从环境化学的角度,对土壤草甘膦的环境残余水平进行综述,对土壤环境样品中草甘膦痕量残余检测方法及技术研究进展做了评述。
China is a large producer and user of glyphosate herbicide.As glyphosate can be adsorbed to soil strongly and has a slow degradation rate,the residue level in soil would increase due to high dosage application and reuse of glyphosate during crops rotation.In China,standard method for glyphosate residue determination in soil environment has not been established,and very little information of glyphosate about environmental residues and its ecological effects is publicly available.To study glyphosate environmental behaviors and its ecological risk assessment are very important for the ecological safety construction,which can promote the strategy management for using herbicide safely.In this paper,the environmental residue level of glyphosate was described and analyzed based on the global glyphosate application and its environmental behaviors.The methods and techniques for trace residue detection of glyphosate in environmental samples were also reviewed and evaluated.
