The migration of metals and metalloids between bottom sediments and water and the other way round is a complex process. Understanding those mechanisms is essential for recognizing transformations taking place in water reservoir ecosystems. The objective behind the following study was to define time and spatial correlations in the changes in total concentrations of selected elements (Cr, Zn, Co, Mn, Cu, Ni, Pb, As, Ba, Sb, Sr and V) in waters and bottom sediments from two water reservoirs located in Upper Silesia (Poland), i.e., Pławniowice and Dzierżno Małe. The research was carried out to demonstrate whether the bottom sediments deposited in the discussed reservoirs could pose an environmental threat due to the possible release of toxic metals and metalloids into the pelagic zone. The obtained results constitute material helping to describe the bioavailability of particular elements. They also expose the existing environmental threats for such water reservoirs and their users.
底泥和水体之间以及水体和底泥之间的金属和类金属元素的迁移是一个复杂的过程。了解这些机制对于识别水生态系统中发生的转化至关重要。本研究的目的是确定位于上西里西亚（波兰）的两个水库（即普拉夫尼维采和德尔日诺马莱）的水体和底泥中选定元素（Cr、Zn、Co、Mn、Cu、Ni、Pb、As、Ba、Sb、Sr 和 V）总浓度变化的时间和空间相关性。开展这项研究是为了证明储存在讨论中的水库中的底泥是否会由于有毒金属和类金属元素可能释放到浮游区而对环境构成威胁。获得的结果构成了有助于描述特定元素生物利用度的材料。它们还揭示了这些水库及其使用者所面临的现有环境威胁。
