Hg Geochemical Character on Soil of Xianling of Ming Dynasty

Abstract

we investigated characteristics of soil Hg,soil gas Hg and atmospheric Hg on tomb of Ming Xianling. Xianling is the tomb of the fourth emperor Zhu Gaochi of the Ming Dynasty.Soil samples were collected for determination of mercury. Soil gas Hg and atmospheric Hg is analysed on high mercury anomalous areas. The results showed that soil Hg on Treasure Town is close to natural background and on Five Offerings is enriched or anomalous. The content of soil Hg is enriched in the surface soil layer.Soil gas Hg is high on Hg enrichments. Atmospheric Hg is low on the survey areas. Meteorological conditions influence mercury flux of emission from Soil to atmosphere. Soil gas Hg is directly affected by the soil Hg.In history, the use of mercury in the mausoleum is a very common phenomenon. Study on the geochemical characteristics of mercury provides the scientific basis for environmental protection and historical research.
