• 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 (Hg T) accumulation in topsoils (0–15 cm) 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 1.5 km, which is probably due to the quick deposition process of particulate Hg and reactive gaseous Hg emitted from the smelters. The total accumulation of Hg T in the topsoils of the study area of 10.9 km 2 is approximately 365–561 kg and of which 346–543 kg might be contributed by anthropogenic emission alone with an annual emission of 17.3–27.2 kg Hg to the topsoils. Secondary copper smelters in Fuyang release a considerable amount of mercury into topsoils.
