The study was carried out to define the distribution of mercury in surface soils in the Mitrovica region, Republic of Kosovo and to assess the level and extent of contamination. A total of 156 soil samples were collected from a depth of 5 cm at each grid point of 1.4 × 1.4 km in an area of 301.5 km. The mercury content was found to be between 0.02 mg/kg and 11.16 mg/kg. The average Hg content (0.49 mg/kg) exceeded the mean content in European (0.037 mg/kg) and world (0.06 mg/kg) soils by 13.2 and 8.2 times, respectively. From the calculated enrichment factors (EF) and the geo-accumulation index (I-geo), as well as from the distribution map of Hg content, it is evident that the soils of the study area are highly contaminated with mercury, with extremely high enrichment of Hg in the soils of Zone I, which was classified as the most contaminated zone with Hg and other potentially toxic elements in the study area as well as in the towns of Zveçan and Mitrovica. The higher Hg content is of anthropogenic origin, mainly due to lead and zinc mining and metallurgical activities in the study area. The mercury levels were also found to exceed the New Dutch List target value (0.3 mg/kg) in 90 km of the study area.
本研究旨在确定科索沃共和国米特罗维察地区表层土壤中汞的分布情况，并评估其污染程度和范围。在 301.5 平方公里的区域内，以 1.4×1.4 公里的网格点为单位，从每个网格点的 5 厘米深处采集了 156 个土壤样本。汞含量在 0.02 毫克/千克至 11.16 毫克/千克之间。平均 Hg 含量（0.49 毫克/千克）分别比欧洲（0.037 毫克/千克）和世界（0.06 毫克/千克）土壤的平均值高出 13.2 倍和 8.2 倍。根据计算出的富集因子（EF）和地质累积指数（I-geo），以及 Hg 含量分布地图，研究区的土壤受到了严重的汞污染，Hg 在 I 区土壤中的富集程度极高，该区域被归类为受 Hg 和其他潜在有毒元素污染最严重的区域，也是 Zveçan 和米特罗维察两个城镇的污染最严重区域。较高的 Hg 含量源于人为活动，主要是由于研究区域的铅和锌矿开采和冶金活动。研究区域的 90 公里范围内，汞含量也超过了新荷兰清单的目标值（0.3 毫克/千克）。
