在本研究中，我们旨在调查土壤中汞的污染程度，特别是人为汞的污染程度，并初步估计中国二级铜冶炼厂浙江阜阳表层土壤（0-15cm）的总汞（HgT）累积量。结果表明，冶炼厂附近土壤汞含量在当地冶炼活动后大幅升高。随着距离冶炼厂1.5km，该区域土壤Hg的空间分布呈快速下降趋势，这可能与冶炼厂排放的颗粒汞和活性气态汞的快速沉积过程有关。10.9km2研究区表层土壤中汞的总积累量约为365 ~ 561kg，其中仅人为排放可能贡献346 ~ 543kg，年向表层土壤排放17.3 ~ 27.2 kghg。
In the present study, we aim to investigate the extent of soil contamination by Hg, particularly by anthropogenic Hg, and tentatively estimate the total Hg (HgT) accumulation in topsoils (0–15cm) in Fuyang, Zhejiang Province—a secondary Cu smelter of China. The results show that the levels of soil Hg in the vicinity of the smelters have been substantially elevated following local smelting activities. The spatial distribution of soil Hg in this area reveals a rapid decrease as the distance from the smelter reaches 1.5km, which is probably due to the quick deposition process of particulate Hg and reactive gaseous Hg emitted from the smelters. The total accumulation of HgTin the topsoils of the study area of 10.9km2is approximately 365–561kg and of which 346–543kg might be contributed by anthropogenic emission alone with an annual emission of 17.3–27.2kgHg to the topsoils.
