农产品重金属含量超标风险协同管控研究

我国农产品质量安全问题日益严峻,特别是重金属超标风险尤为突出。综合考虑土壤环境质量与农作物环境响应特性对农产品重金属超标的双重影响,基于农产品品种对重金属吸收/积累特性的差异性分析,阐明了农作物品种优选对农产品质量安全保障作用,提出了在农作物品种审定中增加对重金属的吸收/积累系数指标,建立国家层面的农作物吸收/积累重金属数据系统,探索农产品重金属超标风险的协同管控途径。

Risk control of heavy metal content in agricultural products

The quality and safety of agricultural products in China were serious. Risk of heavy metal content in agricultural products was a prominent problem. Based on the soil and agricultural products'' influence on heavy metal content in agricultural products, the difference of heavy metal concentrations in various crops were analyzed. It illustrated that selection of agricultural product is important for safety of agricultural products quality. This paper presented the methods of risk control, including addition of absorption/accumulation coefficient, the national coefficient database, and integrated management of soil-agricultural products.
