Health Risk Assessment of Heavy Metals in Rural Drinking Waters Around the District of Poyang Lake

HU Chun-hua1.2,ZHOU Wen-bin1,2,HUANG Zong-lan1,2,GUO Chun-jing1,2,WANG Mao-lan1,2(1.Key Lab of Lake Ecology and Bio-resource Utilization of Poyang Lake,Ministry of Education,Nanchang University,Nanchang Jiangxi 330029,China;2.College of Environmental and Chemical Engineering,Nanchang University,Nanchang Jiangxi 330031,China)  
Health risks associated with 4 metals in drinking water are assessed using USEPA health risk assessment model.Results show that the concentration of Pb exceeded Standard for Drinking Water Quality(GB 5749-2006) in Changgu village near Shahu Lake,the center Branch of Ganjiang River and Chucha,so it should be taken seriously.Among the health risks caused by the carcinogens in drinking water,the health risks caused by the non-carcinogenic and carcinogens are much lower than the maximum allowance levels recommended by ICRP(5×10-5·a-1).Among the non-carcinogenic risks in drinking water,the highest risk is the risk associated with Zn,followed by Pb,and then Cu.The health risk of carcinogens is higher than that of non-carcinogens.Therefore,Cd is regarded as the main pollution in drinking water,it contributes to 70.65 to 96.04 percent of the total risks.So the pollution of Cd should be taken first to consider for prevention and treatment.
