中文摘要:

      百草枯是一种具有快速灭生性作用的除草剂, 具触杀与内吸作用, 除草效果好, 加之经济易得, 在农业植保领域使用广泛。但滥用及不合理地使用百草枯的情况时有发生, 对食品安全和环境造成一定的危害, 农业农村部已在公告中禁止该除草剂的使用。由于百草枯的极性高、挥发性差及其在紫外光下的不稳定性, 导致常规仪器对其检测难度大; 另外百草枯在植物源性食品中残留量低, 常需要痕量检测。本文针对上述难点与关键技术问题, 通过国内外文献的综合分析, 系统归纳了百草枯残留检测方法的研究现状, 总结并展望现有分析方法的优缺点和发展趋势, 为开发简单、快速、准确的新技术和新方法提供参考, 为植物源性食品中百草枯的相关安全研究提供技术依据。

英文摘要:

      Paraquat is a kind of herbicide with rapid inactivating action, with poisoning and systemic action, with good herbicidal effect, coupled with economic availability, it is widely used in the field of agricultural plant protection. However, the misuse and irrational use of paraquat has occurred from time to time, causing certain harm to food safety and the environment, and the Ministry of Agriculture and Rural Development has banned the use of this herbicide in the announcement. In view of its high polarity, poor volatility and instability under ultraviolet light, paraquat is difficult to be detected by instrumentation. In addition, paraquat has low residue levels in foods of plant origin, and trace detection are often required. In order to address the above difficulties and key technical problems, this paper summarized the current research status of paraquat residue detection methods through comprehensive analysis of domestic and international literature, summarized and prospected the advantages and disadvantages of the existing analytical methods and the development trend, and provided references for the development of simple, rapid and accurate new technologies and methods, so as to provide a technical basis for the safety research of paraquat in food of plant origin.
