The article presents the results of studying the composition of Malus baccata (L.) Borkh, collected in natural and anthropogenically modified environment of the Republic of Buryatia. We have analyzed the distribution of elements in different organs of Malus baccata. The content of elements Na, Mg, Al, Si, P, S, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Zr, Pb и Ba in soil and Malus samples was determined by the method of X-ray fluorescence (XRF). It was found that the content of oxides of the basic elements in alluvial and ferruginous soils is lower than in the soils of urbanized territories, except for MnO, TiO2 and Fe2O3 oxides, which are characteristic for this type of soil. The greatest amount of Cu, Zn, Ba and Pb has been found in the soils collected from urban streets. The main reason is the urban transport. Fruits contain more essential elements P, K, Cu and Rb compared to leaves, while the leaves contain higher concentrations of potentially toxic Al, Si, Ca, Ti, Mn, Fe, Sr, and Ba. The content of elements in all samples of Malus baccata is significantly lower than toxic or excessive concentrations established for land plants.
