| Abstract: |
| To assess heavy metal pollution in one uranium mine with its surrounding areas and its health risk, 20 groundwater samples were collected in wet, normal and dry season, and concentrations of Mn, Pb, Cr6 , As and Cd in samples were measured. Health risk assessment was conducted with environmental health risk assessment model recommended by USEPA. The results show that total health risk value is in the range of 8.74×10-7~1.06×10-4a-1. Total risk index value (RI) of 95% of samples is lower than the maximum acceptable levels set by ICRP and USEPA. Content of heavy metals in groundwater has no obvious hazards to nearby residents. |
