Health Risk Assessment of Rice Manganese in a Metallic Mining Area

通过对湖南某金属矿冶区稻米锰含量和当地居民膳食结构进行系统调查，考察调查区域的农产品安全现状。依据美国EPA推荐的非致癌污染物健康风险模型进行Monte-Carlo不确定性分析，采用Crystal ball软件对研究区域居民膳食结构进行模拟分析，评估不同人群长期食用当地大米的锰致癌风险。结果表明：该矿冶区居民食用当地大米，锰的健康风险较低，但应警惕儿童易感人群的锰健康风险。 Manganese content in the local rice and the rice dietary of residents in a metallurgy area were in-vestigated on-the-spot. Based on the Monte-Carlo uncertainty analysis of the risk model for health hazard recommended by the USEPA, Mn carcinogenic risk of different populations was evaluated with Crystal ball software. All the results showed that manganese might not be one of the risk fac-tors for an adult exposed through rice consumption.
