目的 近年来我国接连发生的自来水停水事件严重影响城市供水安全,给公众生活和社会秩序带来了很大困扰。鉴于《生活饮用水卫生标准》(GB 5749-2006)中污染物限值确定的依据是基于终生暴露水平的健康风险评价,与污染事件应急处置中常见的污染物短期暴露风险的评价角度不同,从而开展我国饮用水中污染物短期暴露健康风险的研究,确定健康风险参考值的推导方法。方法 饮用水短期暴露健康风险参考值制定的主要步骤包括毒理数据的收集和筛选、分离点的确定、不确定系数的选择和推导健康风险参考值。结果 饮用水污染物短期暴露健康风险参考值的推导公式为HA=(POD×BW/UF×DWI)。结论 本研究提出了饮用水中污染物短期暴露健康风险参考值的制定方法,为完善我国饮用水中污染物健康风险评价体系和污染物的短期健康风险评估与饮用水污染事件应急处置工作提供了技术支持。

Objectives The occurrence of tap-water shutdown event, which was frequent in recent years in China, had serious impact on the safety of water supply, and had great trouble to public life and social order. In light of the limiting value of pollutants in the Standards for Drinking Water Quality(GB 5749-2006)was based on the assessment of health risk exposure to contaminants in drinking water in the lifetime, the point of view on assessing the health risk of acute exposure to contaminants in drinking water during emergent events was different. Thus, a research on the method of deriving a advisory value for the health risk of acute exposure to contaminants in drinking water was carried out. Methods Main steps of deriving advisory values for health risk in acute exposure to contaminants in drinking water included collection and selection of toxicological data, determination of departure points, selection of uncertainty factors and derivation of health risk advisory value. Results The health risk advisory value of acute exposure to contaminants in drinking water was derived from the following equation HA=(POD×BW/UF×DWI). Conclusions The method of deriving health risk advisory values for acute exposure to contaminants in drinking water was put forward in this study, which provided technical support in improving health risk assessment system for assessing health risk and emergent treatment of drinking water pollution events in China.
