Abstract:

In this study, As, Cd, Hg, Pb, F, ammonia nitrogen, and phenol in drinking water of 24 counties and cities in Poyang Lake region were studied according to the USEPA health risk assessment model. The research results showed that the highest risk caused by As and Cd through drinking water were appeared in Pengze (29.1×10-6·a-1) and Poyang County (7.94×10-7·a-1) respectively, while both were lower than the maximum allowance levels recommended by ICPR (5×10- 5·a-1). The highest risk of noncarcinogen caused by phenol was in Poyang County (4.99×10-9·a-1), which was lower than the maximum allowance levels recommended by ICPR. Finally, the total health risks, calculated by adding the carcinogens risks to the non-carcinogenic ones, ranged from 10-6·a-1 to 10-11 ·a-1, which indicates a low risk without health hazards. However, the results revealed a high risk of drinking water in Pengze County, Nanchang city, Nanchang County, Hukou County, so more attention should be paid to the environment in these regions.
