| Abstract: |
| Based on the statistics of literature data related to uranium pollution in soil and water of uranium tailings in southern China in the past 10 years, the distribution and pollution status of uranium in soil and water of uranium tailings were investigated by single factor index and potential ecological hazard index method. The results show that when the background values of each area are taken as reference, the coefficients of variation (CV) of uranium content in soil and water is 109.9% and 103.5%, respectively, indicating uneven distribution of uranium. The single-factor pollution indices of uranium in soil and water ranges from 0.45 to 17.63 and 1.44 to 140.31, with the average values of 4.83 and 24.63, respectively. The Nemero comprehensive pollution index ranges from 0.90 to 13.42 and 4.40 to 425.53, with average values of 13.42 and 46.35, respectively. The potential ecological risk hazard coefficient E_r^i ranges from 17.82 to 705.24, and 57.42 to 5612.24, with average values of 193.19 and 985.03, respectively. The content of uranium in the soil and water of uranium tailings in South China is higher, and the distribution of uranium in each zone is uneven, with large differences. The pollution and ecological risk of soil and water bodies of uranium tailings in South China need to be paid more attentation. |
