贵州省由于它的特殊 geochemical 背景和复杂 Hg 排放来源在中国作为一个重重地弄脏 Hg 的区域被知道。在这研究,我们在 Hg 采矿区域调查了表面土壤样品的 Hg 同位素作文,锌熔炼区域,煤燃烧区域,它被知道是在这个省的 Hg 的典型污染区域。我们也比较了 Hg 主要 Hg 来源的同位素的指纹例如热水的忍受 Hg 矿石,煤和大气的 Hg 样品。根据我们的学习, Hg 在贵州省显示在不同污染区域在表面土壤存储了大量两个集中依赖分别(MDF, 202Hg ) 并且集体独立分别(MIF, 199Hg ) 。202Hg 在 2.0 变化, 199Hg 在调查表面土壤在 0.25 变化。这研究证明用 MDF-MIF,二个维的 Hg 同位素系统能在在土壤区别 Hg 来源是特别地有用的。
Guizhou Province is known as a heavily Hg-polluted area in China due to its special geochemical background and complicated Hg emission sources. In this study, we investigated the Hg isotope compositions of surface soil samples in the Hg mining area, zinc smelting area, coal combustion area, which are known to be the typical pollution regions of Hg in this province. We also compared the Hg isotopic fingerprints of primary Hg sources, such as hydrothermal Hg-bearing ores, coals and atmospheric Hg samples. According to our study, Hg stored in surface soils in different pollution regions in Guizhou Province displays a wide range of both mass dependent fractionation (MDF, δ^202Hg) and mass independent fractionation (MIF, △199Hg). δ202Hg varies by 2.0‰ and △199Hg varies by 0.25‰ in the investigated surface soils, This study demonstrated that using a "MDF-MIF" two dimensional Hg isotope system could be particularly useful in discriminating Hg sources in soils.
