| 摘 要： | 四氯化碳是地下水中常见的有机污染物,文章针对某市南区供水水源地岩溶地下水遭受四氯化碳污染的情况,对供水区人群通过食入和皮肤接触四氯化碳从而对人体健康可能造成的影响进行了风险评价,并分析了该地区多年来健康风险的动态变化。结果显示从2001～2007年供水区人群风险指数整体呈下降趋势,四氯化碳污染所带来的健康危害逐渐减弱。距污染源最近的X-49井是存在风险最大的水井,非致癌指数最高为10.2,致癌指数最高为5.29×10-4,均超过规定标准。

| Abstract: | Carbon tetrachloride as a common groundwater contaminant imperils the health of human. Risk assessment on human health was estimated,including risk caused by ingestion from drinking water and by dermal contact. Dynamic change of health risk was also analyzed. Results showed that risk indexes of human health were in downtrend from 2001 to 2007, with potential weakening of health hazardousness. Risk at X-49 well is maximum with non-carcinogenic index of 10.2 and carcinogenic index of 5.29×10-4,both exceeding the acceptable standard. |
