农产品中新烟碱类农药前处理和检测技术研究进展
新烟碱类农药具有独特新颖的作用方式, 良好的根部内吸性, 高效、广谱和环境兼容性好等特点, 被广泛用于农业生产中, 目前已成为世界上增长速率最快的一类杀虫剂。近年来, 因新烟碱类农药的广泛使用, 该类化合物在食品和环境中不断被检出, 给人类健康及生态环境带来极大的安全隐患。由于检测样品种类繁多, 基质复杂, 农药残留的检测需要进行提取、净化、浓缩、测定等步骤。目前, 常用的前处理方法主要包括液液萃取法、固相萃取法以及新型的基质分散固相萃取和液液微萃取法等; 常用的检测分析方法主要包括光谱法、色谱法、质谱法等。本文结合国内外文献报道, 就农产品中新烟碱类农药残留的前处理技术和检测技术进行归纳和比较, 以期为检测工作者提供参考。
Neonicotinoid pesticides (NPs) have been used in agricultural production because of their unique and novel action mode, good endosuction, efficiency, broad spectrum and good compatibility to environment, which have been the fastest growing class of insecticides in the world. In recent years, neonicotinoid pesticides are detected in food and environment, which have potential risk to humans. Because of the variety and complexity of samples, the determination of pesticides residues includes the following steps: extraction, purification, concentration and detection. The pretreatment technique used for the determination of pesticide residues mainly includes the liquid-liquid extraction, solid-phase extraction, dispersive solid-phase extraction and liquid-phase micro-extraction, as well as the detection technique of pesticide residues includes spectrometry, chromatography, mass spectrometry, and so on. This paper concluded and compared the pretreatment and the detection technology of NPs in agricultural products, which provided a theoretical reference for testing workers.
