To investigate pollution level and ecological risk of mercury in soils of the water-level-fluctuating zone in the Three Gorges Reservoir Region,192 surface soil samples from 14 counties( districts) in Chongqing were obtained. Concentrations of THg and Hg species,bioavailable Hg were analyzed and discussed. Geoaccumulation index( Igeo) and Hkanson potential ecological risk index( Er) were applied to assess the pollution status and potential ecological risk of THg and Hg species,respectively. The results showed that significant differences in the concentration of THg were found in soils of water-level-fluctuating zone in the Three Gorges Reservoir. The THg concentration ranged from 22. 4 to 393. 5 μg·kg-1,with an average of( 84. 2 ±54. 3) μg·kg-1. 76. 6% of the samples' THg content was higher than the soil background value in the Three Gorges Reservoir Region. The percentage of five mercury species( water-soluble Hg,HCl-soluble Hg,KOH-soluble Hg,H2O2-soluble Hg,residue Hg) in soils were 4. 1%,15. 5%,18. 3%, 10. 9%,51. 3%,respectively. The average concentrations of bioavailable mercury varied between 19. 7-36. 6 μg·kg-1,and the percentage of bioavailable Hg was 22. 1%-51. 6% of THg. According to the geoaccumulation index,the soils were lightly polluted by Hg. Hkanson single potential ecological risk index evaluation showed that Hg species had a low potential ecological risk,moreover, soils of water-level-fluctuating zone in the Three Gorges Reservoir were at low ecological risk levels as evaluated by bioavailable Hg. While,the assessment results based on THg of soils was much higher than that based on the Hg species. Two methods of evaluation showed that the Igeoand Ervalues calculated based on the Hg species better reflected the actual pollution levels of soils and its hazard to aquatic organisms.
