桶装纯净水中三种有害元素对人体的健康风险评价

本文根据2001～2004年对桶装纯净水的监测结果,将健康风险评价的方法应用于纯净水的卫生质量评价中,根据相应的数学模型分别计算了桶装纯净水中化学致癌物As和非致癌污染物Pb、Cu通过饮用途径对人体健康的年风险。桶装纯净水中的3种有害元素由饮水途径对人体所致的健康危害程度依次是As>Pb>Cu。其中As是主要的污染,占个人年风险的99.98%。而在非致癌污染物中,Pb又是主要污染,占非致癌污染物个人年风险的82.9%。

Public Health Risk Assessment of Three Harmful Elements in Bottled Purified Water for Drinking

The public health risk assessment was used in bottled purified water for drinking based on the data of 2001～2004. In order to assess the annually health risk caused by arsenic、lead、copper in the bottled purified water for drinking, the models of annually health risk and the methods of exposed dose-reactivity extrapolation were applied. The personal excess dangerous model was used. In the purified water, chemical carcinopen-arsenic was the primary pollutant. It caused 99.98% personal annual risk. In the non- chemical carcinopen, lead was the main pollutant. It caused 82.9% personal annual risk.
