水源地环境污染的健康风险包括化学物的致癌风险、躯体损害风险和辐射伤害风险，通过各自的剂量-反应关系，可建立3类风险的计算模型。在对部分参数进行适应性调整的基础上，运用这些模型对扬州市四水厂进行了分析评价。结果表明，该水源地水体中痕量有毒有害污染物所致健康危害总风险值为4?87×10-8 a-1，远低于EPA推荐的风险限值，削减具有潜在致癌效应的卤代烃类排放是控制风险的关键。
水源地環境汙染的健康風險包括化學物的緻癌風險、軀體損害風險和輻射傷害風險，通過各自的劑量-反應關繫，可建立3類風險的計算模型。在對部分參數進行適應性調整的基礎上，運用這些模型對颺州市四水廠進行瞭分析評價。結果錶明，該水源地水體中痕量有毒有害汙染物所緻健康危害總風險值為4?87×10-8 a-1，遠低于EPA推薦的風險限值，削減具有潛在緻癌效應的滷代烴類排放是控製風險的關鍵。

Environmental health risk of drinking water source was derived from carcinogen、non-carcinogenic poison and radiation. The computational models of these three type risk were established on their dose-reaction relations. In this paper, these models were applied to assess the health risk of№4 waterworks in Yangzhou based on some parameters adjustment. The results indicated that the health risk caused by trace toxic and harmful pollutants in this drinking water source was 4?87 × 10 -8 a-1 . The risk was much lower than the value recommended by EPA. The key to control risk of this drinking water source was reducing emissions of halohydrocarbon having potential carcinogenic effect.
