中文摘要:

      梨以其独特的口感和风味深受人们的喜爱, 在全球范围内被广泛种植和消费。农药作为保障梨生产必需的投入品之一, 在病虫害防控方面发挥了积极作用, 但同时带来了农药残留污染问题, 成为影响梨品质安全的重要因素之一。本文介绍了我国梨生产上农药登记的现状, 分析了国内外梨农药残留污染的特点, 概述了近年来梨中农药残留消解研究情况, 综述了梨中农药残留主要的检测技术及其研究进展, 包括固相萃取、分散固相萃取、快速滤过型净化、阵列式薄膜固相微萃取等前处理方法, 以及三重四极杆质谱、四极杆-飞行时间质谱、表面增强拉曼光谱、免疫分析等检测技术。文章还指出了当前研究尚存的不足之处, 并提出了今后研究工作的建议, 旨在为开展梨中农药残留研究提供参考。

英文摘要:

      Pyrus spp. are cherished by consumers for their unique taste and flavor, which has led to their widespread cultivation and consumption around the globe. Pesticides, an essential input for Pyrus spp. production, are vital in the prevention and control of pests and diseases; however, they also contribute to the issue of pesticide residues, which has emerged as a significant concern affecting the quality and safety of Pyrus spp. products. This paper briefly described the registered and commonly used pesticides in China’s Pyrus spp. production, analyzed the contamination characteristics of pesticide residues in Pyrus spp. both domestically and internationally, discussed recent findings on the dissipation of pesticide residues in Pyrus spp., reviewed principal analysis techniques and recent advancements for their determination, including sample preparations such as solid phase extraction, dispersive solid phase extraction, multi-plug filtration cleanup, and array-thin film micro-extraction, as well as analytical procedures like triple quadrupole mass spectrometry, quadrupole-time-of-flight mass spectrometry, surface-enhanced raman scattering, and immunoassay, and offered current shortcomings and future research recommendations in this field. This review aims to provide valuable references for ongoing studies on pesticide residues in Pyrus spp.
