| 中文摘要: |
| 通过在某燃煤电厂周边河流中布设15个采样点，监测其中氟（F）、砷（As）和重金属的含量，并评价其通过饮水和皮肤接触途径对不同人群所产生的健康风险。结果表明：河流中F、As、Cd、Cr监测值均未超过《地表水环境质量标准》（GB 3838—2002）Ⅲ类标准限值，Hg严重超标；河流中污染物所致儿童和成人健康危害的总风险分别为262×10-5 a-1和176×10-5 a-1，均高于瑞典环保局、荷兰建设和环境部推荐的最大可接受风险水平10×10-6 a-1，其中As、Cr对儿童的健康危害风险较大，分别为169×10-5 a-1和921×10-6 a-1，应作为风险决策管理的重点。 |
| 英文摘要: |
| The health risks of fluorine， arsenic and heavy metals through drinking water and dermal exposure were evaluated base on the monitoring data from fifteen sampling sites in river around a coal fired power plant. The results showed that the concentration of F， As， Cd， Cr were below the standard limits of grade Ⅲ in Environmental Quality Standards for Surface Water （GB 3838—2002）. The concentration of Hg seriously exceeded the standard limit. The total health risk of the pollutants for children and adult were 2.62×10-5 a-1 and 1.76×10-5 a-1， respectively， both were higher than the maximum acceptable risk of 1.0×10-6 a-1 recommended by Sweden and Holland Environmental Protection Bureau. As and Cr had severe health risks for children with the total health risk of 1.69×10-5a-1 and 9.21×10-6a-1， respectively， and should be regarded as the targets of risk control. |
