背景、目标和范围。本研究的目的是检查铅锌矿开采和冶炼厂附近采集的水样中某些元素的浓度，并将获得的数据与来自同一水库的沉积物样品所获得的结果进行比较。目的。这里对从波兰 3 个大型铅锌冶炼厂附近的水库采集的 8 个水样和 3 个底部沉积物进行了分析。 方法。通过 0.45 μm 过滤器过滤并将 pH 值调节至 2 后进行水分析。为了分解干燥的沉积物样品，采用微波辅助消化并完全溶解硅酸盐基质。使用 ICP-MS 和 ICP-OES 方法测定所研究的元素。结果与讨论。水样中大多数研究元素的浓度都在0.Xμg/L水平，只有两个水库中的Tl、As、Mn、Cd、Pb和Sb含量超出了饮用水标准。沉积物中所研究的金属含量范围很广，从 X mg/kg（Se 和 Sb）到 X000 mg/kg（Pb 和 Zn）。结论和建议。研究表明，Tl、As、Cd、Cu、Mn、Pb、Zn、Se 和 Sb 对底部沉积物的影响比对浮选后废物堆附近池塘水的影响要广泛得多。对地表水和地下水的监测如果仅限于溶解元素，可能会导致关于环境污染的错误结论。底层沉积物主要含有易流动相，水沙平衡容易改变。
Background, Goal and Scope. The aim of this study was to check the concentration of some elements in water samples collected near Pb-Zn mining and smelting works and comparison of the obtained data with results achieved for sediment samples originated from the same reservoirs.Objective. Here, 8 water samples and 3 bottom sediments collected from water reservoirs in the vicinity of 3 big Polish Pb-Zn smelters were analysed.Methods. Water analysis was performed after filtration through a 0.45 mu m filter and pH adjustment to 2. For decomposition of dried sediment samples, microwave assisted digestion with total dissolution of silicate matrix was applied. The elements studied were determined using ICP-MS and ICP-OES methods.Results and Discussion. The concentrations of most studied elements in water samples were on the O.X mu g/L level, while only the contents of Tl, As, Mn, Cd, Pb and Sb in two water reservoirs were above the limits established for drinking water. The content of studied metals in sediments was in a wide range from X mg/kg (Se and Sb) to X000 mg/kg (Pb and Zn).Conclusions and Recommendation. The study indicates that the impact of Tl, As, Cd, Cu, Mn, Pb, Zn, Se and Sb on bottom sediments is much more extensive than on the water in ponds located in the vicinity of a post-flotation waste heap. Monitoring of surface and underground waters, if limited only to the dissolved elements, can lead to faulty conclusions about environmental pollution. The bottom sediments mainly contain easily mobilised phases, and water-sediment equilibrium could be changed easily.
