中文摘要:

      拟除虫菊酯类农药是一类高效、低毒、广谱杀虫剂, 大量用于农业生产, 其残留广泛分布于食物链中, 对人类的食品安全构成威胁。随着人类生活水平的提高, 人们对食品质量安全愈加重视。因此, 建立各种食品基质中拟除虫菊酯类农药残留量可靠的分析测定方法十分必要。而在整个样品分析过程中, 前处理环节是瓶颈。本文重点对近年来不同基质源食品中拟除虫菊酯类农药残留分析的样品前处理技术和方法进行综述, 主要总结了植物源食品(水果、蔬菜和食用油等)和动物源食品(肉、蛋、奶以及水产品等)基质中菊酯类农药残留提取、净化和富集等前处理步骤, 同时, 对常用的前处理方法的优点和限制因素进行了比较, 并对具有发展前景的前处理技术进行了展望。

英文摘要:

      Pyrethroid pesticides are highly effective, low-toxic and broad-spectrum pesticides, which are widely used in agricultural production. Their residues are widely distributed in the food chain and pose a threat to human food safety. With the improvement of human living standard, people pay more and more attention to food quality and safety. Therefore, it is necessary to establish a reliable method for the determination of pyrethroid pesticide residues in various food substrates. In the whole process of sample analysis, pretreatment is the bottleneck. This paper reviewed the techniques and methods of sample pretreatment for the analysis of pyrethroid pesticide residues in food from different matrix sources in recent years, mainly summarized the extraction, purification and enrichment of pyrethroid pesticide residues in plant-derived food (fruits, vegetables and edible oils) and animal-derived food (meat, eggs, milk and aquatic products). At the same time, this paper compared the advantages and limitations of the common pretreatment methods, and also discussed the prospect of the pretreatment techniques.
