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 o f 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 m ainly derived from the conversion o f mercury. The geoaccumulation index showed that the pollution degree o f Hg was very highly polluted; the results o f the potential ecological risk index showed that both Hg and MeHg showed extremely highly polluted level, and the ecological risk was very high.
