摘要
Abstract
Mathematical models were established to assess the health risk from both gene and non-gene toxic substances in drinking water sources. Based on the data determined in Yucheng District of Ya＇an City, the health risk was assessed and analyzed. The results showed： 1. the annual personal risk of gene toxic substances via drinking water ranked as Cr（VI） 〉 As 〉 Cd, and that of non-gene toxic substances ranked as Hg 〉 Pb 〉 Mn 〉 Fe. However, the effects of former group of substances were much greater than the latter group of substances ; 2. health risk caused by three gene toxic substances in water sources were much higher than 1.00×10^-6a^-1, the maximal acceptable level recommended by Sweden Bureau of Environmental Protection and Holland Ministry of Construction ＆ Environmental Protection. Additionally, the personal health risk caused by Cr （VI） was higher than 5.00×10^-5a^-1, the maximal acceptable level recommended by ICRP. Therefore Cr（VI） should have the priority to be treated as a pollutant in drinking water in this area.关键词
