常州饮用水源地挥发性有机物预警监控和健康风险评价研究

摘要

通过对2013年至2014年常州市魏村水厂和西石桥水厂饮用水源地水质自动监测站挥发性有机物在线分析仪的数据进行研究，并采用USEPA的暴露计算方法对常州市饮用水中挥发性有机物污染状况和健康风险进行了调查评价。结果表明，两个水源地所监测的挥发性有机物含量均符合生活饮用水标准，且整体年均非致癌和致癌风险均远低于USEPA推荐的限值，对人体危害微乎其微。而在最不利的情况下，两个饮用水源地水体非致癌和致癌风险均处在安全范围内。%This paper analyzed data from VOCs online analyzer collected from automatic water quality monitoring station of Wei Village and Xi Shi-qiao in Changzhou during 2013 to 2014.The pollution status of VOCs in drinking water and health risks of drinking water in Changzhou were investigated by using USEPA method .The results show that are in line with the two sources of water to the monitoring of VOCs in drinking water standard of living , and the overall annual non carcinogenic and cancer risk are far below the USEPA recommends the limit value , the minimal damage to the human body .In the most adverse circum-stances, the two drinking water sources of non carcinogenic and carcinogenic risks are in the safe range .
