地下水污染健康风险评价方法

为了探讨构建适合我国国情的地下水污染健康风险评价体系,在综合分析国内外有关地下水污染风险评价的研究方法的基础上,初步探索建立了一套地下水污染健康风险评价方法。该评价方法包括危害识别、剂量-效应分析、暴露评价及风险表征4个步骤,对每一步骤进行了详细的探讨,提出了危害识别与判定方法及原则,毒性因子查询、暴露量和风险计算等方法,以及有关建立我国地下水污染健康风险评价体系方面的一些建议。

Method for Health Risk Assessment of Groundwater Pollution

To construct a health risk assessment system of groundwater pollution,the authors have attempted to establish a groundwater pollution health risk assessment methods,based on the comprehensive analysis the research results on the health risk assessment of groundwater.The assessment method includes four steps,i.e.,hazard identification,dose-response assessment,exposure assessment and risk characterization.This paper had proposed determining methods and principles of hazard identification,enquiring methods of toxicity factor,calculating methods of exposure and risk,and some advices about establishment of groundwater pollution risk assessment system in China.
