Sadržaj potencijalno toksičnih elemenata u odabranim drvenastim vrstama kao bioindikatorima zagađenja obalne zone reke Save
The content of potentially toxic elements in selected woody species as bioindicators of pollution in the riparian zone of the River Sava
Abstract:
The research conducted as part of this doctoral dissertation was aimed at examining the accumulation and translocation of potentially toxic chemical elements (Al, As, B, Cd, Cr, Cu, Fe, Li, Mn, Ni, Pb, Se, Sr and Zn) in selected woody plant species (Salix alba L., Populus nigra L., Populus alba L., Ulmus glabra Huds. and Juglans regia L.) in floodplain forests in the riparian zone of the River Sava. The physical and chemical characteristics of the soil were analysed, the most important factors influencing the uptake of potentially toxic elements by the examined species were defined, and the species’ potential for the bioindication and phytoremediation of these elements was determined. The research was conducted in the riparian zone of the River Sava in Slovenia, Croatia, and Serbia, at sites exposed to various sources of pollution (Mojstrana, Radovljica, Litija, Vrhovo, Čatež, Zagreb, Jasenovac, Slavonski Brod, Županja, Sremska Mitrovica, Šabac and Belgrade). The results indicate the examined species’ potential for being used in the bioindication, biomonitoring and phytoremediation of potentially toxic elements. The species S. alba is a good bioindicator for the presence of all the analysed PTEs in the soil, except Sr. P. nigra is a good bioindicator for the presence of As, B, Fe, Li, Mn, Ni and Pb, while P. alba is a bioindicator for the presence of B, Cd, Cr, Fe, Mn, Ni and Zn in soil. The species U. glabra proved to be good for the bioindication of the presence of As, B, Cd, Cr, Mn, Ni and Zn, and the species J. regia for the bioindication of Al, B, Cd, Cr, Cu, Fe, Li, Mn, Ni, Pb and Zn content in the soil. However, the investigated species cannot be reliably used for the bioindication of Sr in the study area.
