中文摘要:

      世界上农药年产量高于200万吨, 有1000多种人工合成化合物被用作杀虫剂、杀藻剂、除虫剂、杀菌剂、落叶剂等农药。有机农药的大量施用会造成严重的污染问题, 并对人体健康造成严重威胁。因此, 建立简单、高效和成本低的农药残留快速检测方法非常重要。由于农残检测涉及的样品种类繁多、样品组成复杂和样品形态多变, 这对农残检测造成的干扰增加, 所以需要选择和改进农药残留检测的前处理方法。科研人员在农药残留快速检测技术方面做了大量的研究, 并取得了较大的进步。本文介绍了该领域一些热点技术的研究方法和动态, 并对存在问题进行了分析, 以期为农药残留快速检测的深入研究提供参考。

英文摘要:

      The world’s annual pesticide production is more than 2 million tons, and more than 1, 000 synthetic compounds are used as pesticides, algicides, insecticides, fungicides, defoliants and other pesticides. The large-scale application of organic pesticides causes serious pollution problems and poses a serious threat to human health. Therefore, it is very important to establish a simple, efficient and low-cost method for rapid detection of pesticide residues. Due to the wide variety of samples involved in pesticide residue detection, complex sample composition and variable sample morphology, this has increased the number of interference factors caused by pesticide residue detection. Therefore, it is necessary to select and improve the pretreatment method for pesticide residue detection. Researchers have done a lot of researches on the rapid detection technology of pesticide residues, and have made great progress. This paper introduced the research methods and dynamics of some hot technologies in this field, and analyzed the existing problems, in order to provide reference for the in-depth study of rapid detection of pesticide residues.
