摘要：

This paper studied the mercury pollution in the soil around a mercury mine and conducted an environmental risk assessment, The results showed that the mercury pollution in the area was serious. and the maximum landing concentration of total mercury (Hg) and methylmercury (MeHg) was 800 meters downwind from the mercury mine There was a significant positive correlation between THg and MeHg (r = 0.87. P<0.01). indicating that the MeHg in soil was mainly derived from the conversion of mercury. The geoaccumulation index showed that the pollution degree of Hg was very highly polluted; the results of the potential ecological risk index showed that both Hg and MeHg showed extremely highly polluted level, and thc ecological risk was very high.
