摘要： 利用水环境健康风险评价模型,选取1995—2004年水质监测数据,对第二松花江干流10个断面由饮水途径引起的水环境健康风险进行了评价。结果表明,二松干流对人体健康危害最大的是化学致癌物Cr(VI);化学致癌物对人体健康危害的个人年风险远远超过非致癌物的个人年风险;1995—2004年有毒有害物质健康总风险超标的断面健康风险值普遍呈现减小的趋势,但2004年仍然有6个断面健康风险超标,主要原因是水体中Cr(VI)和As的浓度过高,因此对排入二松干流的含Cr(VI)和As废水进行控制和治理是降低水环境健康风险的有效途径。

Abstract: This paper assesses the environmental health risk through drinking water based on the model for water environmental health risk analysis and the monitoring data from 1995 to 2004.The results show that the greatest health risks for individual person per year is caused by Cr(VI);the health risk of carcinogens is much higher than the health risk of non-carcinogens;the health risk in the sections which is higher than the standard value recommended by ICRP has decreased from 1995 to 2004,but the health risk in six sections is still higher than the standard value in 2004 which caused by the high concentrations of Cr(VI)and As.So the effective way of decreasing the health risk is to control and dispose the wastewater containing Cr(VI)and As discharging into the Second Songhua River.

Key words: model, water environment, water quality, health risk assessment
