摘要
噻虫嗪是第二代新烟碱类杀虫剂的代表品种,具有杀虫谱广、速效性好、持效期长的特点,在蔬菜、瓜果、水稻等作物上广泛使用。近些年该类药剂对环境有益生物(如蜜蜂等)的负面效应逐渐引起国内外的广泛关注,许多国家对其残留限量做出明确规定。为满足不同种农产品中噻虫嗪残留限量的检测要求,发展简单、快速、灵敏、可靠的检测方法尤为重要。对近年来噻虫嗪在蔬菜、瓜果、茶叶及粮食作物中的残留分析方法进行系统的综述,包括样品处理、提取技术、净化技术及检测技术等过程中所用到的各种方法进行科学严密的比对和分析,并对今后其检测技术进行了展望,以期为今后农产品中噻虫嗪的分析研究提供参考,并为环境安全性进一步评估提供借鉴。
Thiamethoxam,one of the representative products of the second generation of neonicotinoid insecticides with broad insecticidal spectrum,quick speed,and long available period,has been applied to many kinds of agricultural products,including vegetables,fruits and rice,etc.The negative effect of thiamethoxam on beneficial organisms,i.e.,bees,has gradually obtained popular attention in the world;therefore,the regulation on the maximum residue limit(MRLs)of thiamethoxam has been established in many countries.It is necessary to develop simple,fast,sensitive and reliable detection methods in order to meet the detection requirements of thiamethoxam residue limits in various agricultural products.The detection methods of thiamethoxam residues in all sorts of agricultural products in recent years were systematically summarized,including comparison and analysis of the aspects of sample preparation,extraction,clean-up,measurement techniques,and so on.The development prospects of the detection methods were also discussed in the end,so that some scientific research can be provided for future research,and also provide reference for the further evaluation of environmental safety.
