| Abstract: | The suitability of linden and elder as biomonitors was evaluated in the tourist zone of the Bor region well known for pyrometallurgical copper production. The concentrations of As, Cu, Pb and Zn in the soil, washed and unwashed leaves and roots of linden and elder were determined. The absorption of As, Cu, Pb and Zn from soil to roots and leaves, as well as the translocation of the studied elements from roots to leaves, was analysed. It was observed that the soil in the tourist zone of Bor (Bor lake and Brestovac spa) was greatly polluted with Cu and As. Linden and elder leaves can be used as a low-cost material for detection of As, Cu, Pb and Zn in the atmospheric deposition, which was concluded due to the amounts of these elements removed after a washing treatment. Thus, canopies of linden and elder might have an important role in the removal of the polluting substances from the air. The elder leaves were more suitable to be used for indication of environmental pollution with As, Cu and Pb than the linden leaves. The area of the Bor lake sampling site had higher air pollution with As and Pb than Brestovac spa, since greater amounts of As and Pb were washed off the linden and elder leaves from the Bor lake sampling site. The linden and elder used different adaptation strategies in conditions of the increased soil and air pollution. These strategies were based on different efficiencies of element absorption from the soil and on limited or efficient translocation of the studied elements from roots to leaves, and therefore, they have an important role in the biogeochemical cycling of the examined elements in the environment. |
