| Summary: | Title screen The aim of this work is the research of elemental composition of epiphytic lichens growing in the areas of the influence of tailings from mining and the detection of indicative pollutants entering the environment in these regions. The samples of lichens of two species Hypogymnia physodes and Evernia mesomorphawere collected in the summer 2015 in the territories adjacent to the Ursk and Komsomolsk tailings in Kemerovo region (Russia).The concentrations of chemical elements in 49 samples were determined by the mass spectrometry with inductively coupled plasma. The results showed higher concentrations of Sb (Cс = 17,4), As (3,3), and Hg (2,5) in the lichens from the Komsomolsk tailings in comparison with the local background values. Maximal concentrations were found in the northeasterndirection from the tailings -near the lake formed after the mined carrier, where the sulfides have beentransformed into other mineral forms due to the hypergenesis process. The chemical elements, containing in these minerals, migrate and pollute all environmental components. The ecological-geochemical specificity of the Ursk tailings consists in the high concentrating by lichens of Ba (Сс = 62), Sb (22), Hg (16), Ag (13,6), Mn (10), Pb (9,3) and As (4,1). This specificity is determined by the waste composition of the Ursk tailing dump formed from the cyanidation of Hg-containing sulfide ores of the Novo-Urskoe deposit. The results of this research testify that the elemental composition of lichens is directly related to the specificity of the matter composition of the tailings from mining and ore processing.
