摘要
新烟碱类农药的大量使用导致其在水环境中普遍存在,对生态系统和人体健康构成巨大威胁.传统的生物处理技术对新烟碱类农药几乎没有去除效果,高效的去除技术成为目前水环境领域的研究热点.本文系统分析了水环境中新烟碱类农药的来源、危害及污染现状,综述了物理、化学和生物去除技术的研究进展,重点讨论了高级氧化技术,详细阐述了不同技术对新烟碱类农药的去除效果、机理及影响因素等,并指出了各技术的应用优势和限制,最后对新烟碱类农药去除技术的研究提出了展望.
The widespread use of neonicotinoid pesticides has resulted in their ubiquitous occurrence in aquatic environments,which may pose a significant risk to both ecosystems and human health.Neonicotinoids appear to be poorly removed via conventional biological treatment,and thus exploring an effective method has become a research hotspot in the field of water environment.This paper reviewed the sources and hazards of neonicotinoid contamination as well as the concentration levels in the global water bodies.The research progresses on the existing treatment techniques including physical,chemical and biological methods were summarized,of which the advanced oxidation technologies were described in detail.The removal efficiency,mechanism,and influencing factors of different technologies were discussed,and then the advantages and limitations of these treatments were presented.Finally,the future prospect was proposed.
