【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2.62×10^-5 a^-1和1.76×10^-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1.0×10^-6 a^-1,其中As、Cr对儿童的健康危害风险较大,分别为1.69×10^-5 a^-1和9.21×10^-6 a^-1,应作为风险决策管理的重点。更多还原

【Abstract】 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.更多还原
