Geochemical distribution of elements in waters and sediments of the Plesenska River with a special focus on the presence of heavy metals

This paper presents the data from laboratory analyses of water and sediments in autumn and early spring (September 2024 and February 2025). The analyses included waters and sediments from the Plesenska River and the confluence of the Kiselica River with the Zletovska River, as well as a spring located in the immediate vicinity of the Plesenska River. Water analyses were conducted to assess the actual condition and geochemical distribution of elements during the two studied periods, with a special focus on the presence of heavy metals. To obtain additional information about the components transported by the water flow and to gain insight into the cause-and-effect relationships and mechanisms, sediment examinations were also performed.
