湖南省大米中镉污染风险监测现状分析及应对策略

Analysis Monitoring Status and Countermeasure of Cadmium Pollution in Rice in Hunan Province

为充分利用各系统收集的监测数据,实现基于风险的食品安全精准管控,本研究以湖南省大米中镉污染风险监测工作实践为基础,系统分析当前大米镉污染风险监测工作现状和存在的主要问题,并从信息化建设的角度提出一系列应对策略,包括通过数据共享建立大米镉污染特征资源库,掌握大米产业全链条时空污染分布规律;建立'环境—大米—健康'风险识别数据库,掌握大米镉污染来源以及对人体健康影响;通过建立全链条数据编码库实现多源数据融合,为数据共享提供基础;最终,建立全链条大米镉污染风险监测预警平台。该平台可以提高数据的综合利用度,为食品安全风险管理提供技术支持;为降低大米镉污染健康风险至人体、社会可接受的水平,提出消费建议和行业技术支持。本研究的设计思路和方法能为构建跨部门跨行业的食品安全风险监测数据共享系统提供借鉴思路。

To take full advantage of each system’s monitoring data to achieve precision control based on the risk of food safety,this study systematically analyzes the monitoring status and the existing main problems based on the practice of cadmium pollution of rice in Hunan,and proposes a series of coping strategies from the view of information construction,including the establishment of a database of cadmium pollution characteristics in rice through data sharing,which can grasp the spatial and temporal pollution distribution law of the whole chain of rice industry.The risk identification database of environment-rice-health was established to trace the sources and health effects of cadmium pollution in rice.Multi-source data fusion was achieved by establishing the whole chain data coding library,which provides the basis for data sharing.Finally,a monitoring and warning platform was established for cadmium pollution risk in the whole chain of rice by data mining.The platform can improve the comprehensive utilization of data and work efficiency,and more importantly,it will provide technical support for food safety risk management,reduce the health risk of cadmium pollution in rice to acceptable level for human body and society,and propose the consumer suggestions and industry technical support.The design ideas and method of this study can provide reference for the construction of cross-sector and cross-industry data sharing system of food safety risk monitoring.
