摘　　要：镉是一种对环境和人体健康有害的重金属,虽然基于原子吸收光谱仪和电感耦合等离子体质谱仪等大型仪器的常规检测方法准确度高,但不能满足快速现场检测和高通量筛查的需求。镉的原位快速检测技术,可以在粮食安全、农业物联网、生物育种和环境监测等领域提供一种新型、高效、实时的方法,特别是在筛选不同镉吸收和积累特性的植物品种方面具有很大的应用潜力。本文从检测技术原理和特点入手,总结了针对动植物体内重金属镉的快速原位检测的不同技术,如电化学传感技术、荧光传感技术、光学传感器技术等,及其在食品安全监测、风险评估和在生物体内的迁移、转化和积累等领域的研究进展、应用前景和发展方向,以期为相关的科研工作提供技术参考。Cadmium is a kind of heavy metal,which is harmful to environment and human health.Although conventional detection methods based on large instruments such as atomic absorption spectrometers and inductively coupled plasma mass spectrometers have high accuracy,they cannot meet the needs of rapid field detection and high throughput screening.The in situ rapid detection technology of cadmium can provide a new,efficient and real-time method in the fields of food security,agricultural Internet of things,biological breeding and environmental monitoring,especially in the screening of plant varieties with different cadmium absorption and accumulation characteristics.Starting with the principle and characteristics of detection technology,this paper summarized different technologies for rapid in situ detection of cadmium in animals and plants,such as electrochemical sensing technology,fluorescence sensing technology,optical sensor technology,etc.,and its research progress,application prospects and development direction in the fields of food safety monitoring,risk assessment,and migration,transformation and accumulation in organisms.It is hoped to provide technical reference for related research and analysis.
