农产品中内吸性农药残留检测技术与研究进展

Advances in Detection of Systemic Pesticide Residues in Agricultural Products

内吸性农药是一类能在植物生长过程中被植物种子、根、茎和叶吸收,并在植物体内进行传导扩散的农药。其可进入植物组织和器官内部,起到很好的除虫害效果,具有用药简单、药效时间长、雨水影响小和能有效杀灭隐藏害虫等优点,但上述优点使其在食品安全检测中存在残留时间长、提取困难和检测结果偏低或漏检等诸多缺点。综述了近五年来内吸性农药的特点、检测方法及其存在的问题,并对其检测技术的发展进行展望。

Systemic pesticides are a group of pesticides that can be absorbed by plant seeds,roots,stems,and leaves during plant growth,and conduct conduction and diffusion within the tissues and organs of plants.It can enter the inside of plant tissues and organs to play a good role in microorganism and insect control.It has the advantages of simple medication,long efficacy time,less affected by rain and effective killing of hidden pests,but at the same time,the above advantages make it have many disadvantages such as long residual time,difficult extraction,low detection result or missed detection,etc.The work summarizes the characteristics,detection methods and detection problems of systemic pesticides in recent five years,and looks forward to the development of the detection technology.
