摘　　要：随着工业化和城镇化的快速发展,重金属污染问题越来越严重。大米容易吸收和积累有毒重金属元素,食用受重金属污染的大米,容易产生潜在的健康风险。通过健康风险评估能提前预警大米重金属污染对人类造成的威胁。大米重金属暴露评估方法主要包括重金属每日摄入量(EDI)、目标危害系数(THQ)与综合危害指数(HI)等。综合分析了我国部分地区人们摄食大米的重金属暴露参数。The heavy metals pollution is one of the problems that arise due to the rapid development of industrialization and urbanization.Rice can easily absorb and accumulate the toxic heavy metal elements.There are potential health risks via consumption of rice polluted by heavy met-als.By health risk assessment,threats to human caused by heavy metal pollution in rice can be predicted.There are many different health risk as-sessment methods including estimated daily intake （EDI）,target hazard quotient （THQ）,hazard index （HI） and so on.The exposure parameters via consumption of rice in parts of china were analyzed.
