The fate of atmospherically deposited mercury (Hg) was studied in forest soils situated near various Hg anthropogenic emission sources, including chlor-alkali plants, cement production, and pig iron and steel factories in the Czech Republic. Some of these emission sources were more active in the past, while others continue operation with lowered dust and Hg emissions up to the present day. The impact of Hg emission sources on forest soil was assessed with respect to other soil parameters, including organic carbon, soil nitrogen, soil sulfur, and soil oxalate-extractable aluminum and iron concentrations. The site-specific mean Hg concentrations in organic horizons (174–479 μg kg⁻¹) were greater than mean Hg concentrations in mineral soil (15–88 μg kg⁻¹). Site specific mean Hg/C ratios in organic horizons at four study sites ranged from 0.8 to 2.4 μg g⁻¹, while mean mineral soil Hg/C varied from 2.0 to 3.4 μg g⁻¹. Near cement plants, an 8- to 30-cm thick layer composed of dust particles was identified below or mixed with current O and A horizon material (Hg concentrations 122 to 401 μg kg⁻¹). Mean mineral soil pools of Hg (13–24 mg m⁻²) dominated over the mean organic horizon Hg pools (2–11 mg m⁻²). Near cement plants and steel works, Hg concentrations and pools in organic horizons and mineral soils were within the range reported from pristine Czech forest soils. Elevated Hg concentrations in organic horizons were found near a chlor-alkali plant. Thermal decomposition analysis indicated that Hg in A horizons at all sites and dust horizons near cement plants was bound similarly to Hg in foliage.

在各种人为汞排放源附近的森林土壤中研究了大气沉积汞（Hg）的命运，这些土壤包括捷克共和国的氯碱工厂，水泥生产以及生铁和钢铁工厂。这些排放源中的一些在过去更加活跃，而其他排放源一直运行到今天为止，粉尘和汞的排放量降低了。评估了汞排放源对森林土壤的影响，涉及其他土壤参数，包括有机碳，土壤氮，土壤硫和草酸盐可提取的铝和铁的浓度。有机层中特定地点的平均Hg浓度（174–479μgkg ^-1）大于矿质土壤中的平均Hg浓度（15–88μgkg ^-1））。在四个研究地点的有机层中，特定地点的平均Hg / C比在0.8到2.4μgg ^-1之间，而矿物质土壤的平均Hg / C在2.0到3.4μgg ^{-1之间变化}。在水泥厂附近，下面发现了一个由尘埃颗粒组成的8至30厘米厚的层，或与当前的O和A层物质（Hg浓度为122至401μgkg ^-1）混合。汞的平均矿质土壤储量（13-24 mg m ^-2）在有机层的平均汞储量（2-11 mg m ^-2）中占主导地位）。在水泥厂和钢厂附近，有机层和矿质土壤中的汞浓度和池均在原始捷克森林土壤中报道的范围内。在氯碱工厂附近发现有机层中的汞浓度升高。热分解分析表明，水泥厂附近所有地点的A层中的Hg和水泥厂附近的粉尘层中的Hg与叶子中的Hg相似。
