环境镉污染健康风险评价指标体系的构建

Health Risk Evaluation Index System of Environmental Cadmium Pollution

目的建立环境镉污染健康风险评价指标体系,为风险评估奠定基础,为风险管理提供理论依据。方法采用德尔菲法和专家会议法相结合确定指标体系。结果构建了包括3项一级指标、6项二级指标和20项三级指标的指标体系,并确定其权重值。结论环境镉污染健康风险评价指标体系构建科学合理,指标体系的完善有待于进一步实证研究。

Objectives To establish a health risk evaluation index system of environmental cadmium pollution, lay the foundation for risk assessment, and provide a theoretical basis for risk management. Methods Delphi method and expert meeting were used to construct the index system. Results A risk evaluation index system was constructed which included 3 first-level indexes, 6 second-level indexes, 20 third-level indexes. Weights of those indexes were determined. Conclusions The method of constructing index system was scientific. The index system needed to be revised and improved in practice.
