摘要:目的  对石家庄市农村饮用水中重金属的健康风险进行评价。方法 于2012年枯水期(4月)和丰水期(7月)分别对10个县的245个行政村的地下水出厂水进行采集检测 ,采用美国环保局(USEPA)推荐的健康风险评价模型对地下水中砷、镉、铬、铅和汞经饮水途径所引起的健康风险做初步评价。结果 3种基因毒物质所引起的健康危害的个人年风险水平由高至低依次为铬(7.79×10-5/年)大于砷(0.50×10-5/年)大于镉(0.09×10-5/年),总健康风险值为8.09×10-5/年,超过国际辐射防护委员会( ICRP) 推荐的最大可接受值(5.0×10-5/年)。铅(8.50×10-10/年)的健康危害的个人年风险水平高于汞(3.23×10-10/年),两者均未超过国际辐射防护委员会( ICRP) 推荐的最大可接受值(5.0×10-5/年)。结论 石家庄市部分县监测点饮用水中铬可能存在一定的健康风险。

Abstract: Objective To assess the health risk for heavy metals in drinking water in the rural areas of Shijiazhuang city. Methods Water samples were collected from the treated groundwater of 245 village waterworks in 10 counties of Shijiazhuang city and were tested during dry and wet season in 2012. The health risk assessment model recommended by U. S. Environmental Protection Agency (USEPA) was used to assess the health risk caused by heavy metals, such as As, Cd, Cr, Pb and Hg in drinking water.  Results. The annual health risk caused by three gene toxic substances for individuals was in order of Cr(7.79×10-5)>As(0.50×10-5)> Cd(0.09×10-5).  The annual total health risk for individuals was 8.09×10-5, which exceeded the maximum tolerable value recommended by International Commission on Radiological Protection (ICRP) (5.0×10-5). The annual health risk for individuals caused by Pb (8.50×10-10) was higher than Hg(5.0×10-5) but lower than the maximum tolerable value recommended by ICRP (5.0×10-5). Conclusion The chromium level in drinking water at partial monitored spots might have some health risks.
