摘要：

The presence of heavy metals (HMs) in aquatic environments poses significant environmental risks due to their persistence, toxic properties, and potential for bioaccumulation in organisms. Their increased concentrations are found in many water bodies, especially post-mining lakes such as Bagry Lake in Cracow. This paper presents the modelling study on the adsorption of Cu, Pb, Zn, Cd, and Co in the bottom sediment of Bagry Lake, considering the temperature effect and the type of fraction (mineral and volatile). The HM concentrations from the clay-silty fraction (<0.06 mm) sediment were determined using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). HM content in water solutions was determined by Atomic Absorption Spectroscopy (AAS). The Freundlich model shows that the organic fraction has the highest sorption capacity, especially for Pb and Cd. In contrast, the mineral fraction had the lowest sorption efficiency, whereas the sorption was at an intermediate level for the mix of sediment fractions. A developed Thermodynamic Adsorption Model (TAM) has shown that HM accumulation processes can be either spontaneous or non-spontaneous, exothermic or endothermic, with temperature influencing sorption efficiency. This study enhances the understanding of HM accumulation dynamics in sediment systems and provides insights into environmental remediation strategies. © 2025 Elsevier B.V.
