中文摘要： 紧密围绕青年基金,在最大可接受风险水平评估和区域差异性研究方面取得了突破性进展。发表第一或通讯作者论文17篇，含SCI收录8篇；出版专著1本；申请软件著作权2项。基于此,以当前最为关注的重金属污染健康风险为深入剖析对象，将公众风险接受水平分析与健康风险评估、风险调控研究紧密结合，从区域尺度构建适用于我国重金属污染防控需求的人群健康影响评价与风险调控模式。首先根据重金属健康风险特征，筛选典型区域开展重金属环境污染和人群暴露全过程调查分析，估算暴露剂量；结合流行病学调查和统计分析，获得区域重金属敏感性疾病的人群健康响应量；在区域空间维度上进行健康数据与暴露因子之间相关性分析，计算人群健康影响，进而构建健康风险评估模型，得到区域人群的健康风险水平；然后结合风险感知调查获取公众最大可接受风险水平，确定总体风险管理的阈值边界；最后对风险调控情景进行费效分析，结合控制技术可行性，研究最佳风险调控方案。

英文摘要： Supporting by the Natural Youth Fund, many achievements have been made in the field of Maximum Acceptable Risk Level (MARL) assessment and the study of the regional differences, including: 17 papers published as the first or corresponding author, of which 8 are taken by SCI; 1 monograph and 2 software copyrights. Now we’re willing to focus on one of the most concerning risks, the heavy metal pollution, and intend to build the regional public health impact assessment and risk management pattern for the need of China’s heavy metal pollution control by combining the public risk acceptable level analysis with the study of health risk assessment and risk management. In the first step, the whole-process investigations of heavy metal pollution and public exposure are conducted to estimate the exposure dose in the typical areas selected according to the characteristics of heavy metal health risk. Then the public health response to the regional heavy metal diseases can be calculated by applying the epidemiological survey and statistical analysis. Correlation analysis between public health data and exposure factors is also performed in the regional spatial dimensions. Afterwards, a model of health risk assessment is built to evaluate the risk level of regional public health, and the threshold and boundary of the entire ri
