| 摘要: |
| 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 |
|
|
| Abstract: |
| 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. |
