Paper presents results of researches carried out on various locations and immediate vicinity of mining and industrial activities of the northern and south-eastern part of Kosovo. Concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Rn-222, as well as temperature and pH values of natural spring water were measured at 15 measuring sites (that belong to Zvečan, Leposavić and Novo Brdo municipalities), in April-May and September-October 2019. The quantification of heavy metals' content was performed by applying ICP-OES method. In analysed samples a high content of As, Pb, Fe and Ni was found. Carcinogenic and non-carcinogenic risks due to the content of heavy metals in water were evaluated. Concentration of radon in water was measured by the alpha spectrometric method, and measured values range in the interval from 0.34 ± 0.12 to 341 ± 35 Bq/L. The yearly doses of inhalation and ingestion were determined for the measured concentrations of radon. Mutual correlation by the Pearson correlation coefficient, principal component analysis, cluster analysis and spatial distribution analysis of the researched parameters of sampled water were done. The most expressed mutual dependence of some heavy metals leads to the conclusion that they have the same anthropogenic origin.
本文介绍了在科索沃北部和东南部的采矿和工业活动的各个地点及其周边地区进行的研究结果。在 2019 年 4 月至 5 月和 9 月至 10 月期间，在 15 个测量点（属于兹韦钱、莱波萨维奇和新布尔多市）测量了 15 个测量点（属于兹韦钱、莱波萨维奇和新布尔多市）的天然泉水的砷、镉、铬、铜、铁、锰、镍、铅、锌、氡-222 浓度以及温度和 pH 值。采用 ICP-OES 法测定重金属含量。在所分析的样品中发现了高含量的砷、铅、铁和镍。评估了水中重金属含量导致的致癌和非致癌风险。水中氡的浓度采用α能谱法测量，测量值范围在 0.34±0.12 至 341±35 Bq/L 之间。确定了测量浓度的氡的吸入和摄入的年剂量。对采样水的研究参数进行了 Pearson 相关系数、主成分分析、聚类分析和空间分布分析的相互关联。一些重金属之间最明显的相互依赖关系表明它们具有相同的人为来源。
