博罗县水库水环境健康风险评价

Environmental Health Risk Assessment of Reservoirs in Boluo County

根据博罗县域内4个水库的常规水质监测数据,采用水环境健康风险评价模型,对其水质健康危害的风险进行评价。结果表明,2009-2013年,4个水库的水环境健康个人年风险均低于美国环保局和国际放射防护委员会的推荐值,但超过了瑞典荷兰等国环保部门的推荐值。其中,致癌化学物质所致健康危害风险度远高于非致癌化学物质,主要风险因子为致癌化学物质六价铬;致癌化学物质所致健康危害的个人年风险值均呈波动上升,非致癌化学物质所致健康危害的个人年风险值基本维持在较低水平。

Based on water quality monitoring data, the water environmental health risk assessment model of EPA was employed to study the potential health risks of the four reservoirs in Boluo. The results indicated that most of the individual annual health risks in the four reservoirs from 2009 to 2013 were lower than the value recommended by EPA and ICRP, but higher than that of Holland and Sweden. The health risks of carcinogens to individuals were much higher than those of non - carcinogens, the main risk factor wasCr（ VI）. The individual annual health risks of carcinogens to individuals had a trend of rising and the risks of non - carcinogens to individuals remained in a low level.
