第二松花江干流水环境健康风险评价

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.
