摘要
为评价湘江长沙段水环境中污染物对人体健康产生的危害风险,以湘江长沙段2011~2015年的水质监测资料为基础,采用美国环境保护局推荐的健康风险评价模型,对湘江长沙段水环境进行健康风险评价。湘江长沙段由饮水途径所致健康危害的总个人年风险低于国际辐射防护委员会(ICRP)推荐的最大可接受风险水平。化学致癌物由饮水途径所致健康危害的个人年风险顺序为As>Cd;非致癌物由饮水途径所致健康危害的个人年风险顺序为Pb>NH3-N>Cu>挥发酚;化学致癌物对人体健康危害的个人年风险远超过非致癌物。
Based on the local water quality monitoring data from 2011 to 2015, the water environmental health risks assessment model recommended by USEPA was used employed to assess the health risk of Xiangjiang River in Changsha City. Due to drinking water, the general health risks to the individual person per year of Xiangjiang River in Changsha City were lower than the standard value recommended by International Commission on Radiologieal Protection (ICRP) . The health risks to the individual person per year in terms of chemical carcinogens rank as follow As 〉 Cd, while in terms of non-carcinogens rank as Pb 〉 NH3-N 〉 Cu 〉 hydroxybenzenes. The health risks to the individual person caused by chemical carcinogens was far greater than non-carcinogens.
