This work is about the ecological and geochemical assessment of the elemental chemical composition of soil nodules in the taiga zone of the Middle Cis-Urals. The features of the spatial distribution of chemical elements in concretions of Umbric Albeluvisols Abruptic, Luvic Stagnosols Dystric, and Haplic Fluvisols Oxyaquic are characterized for the first time using atomic absorption spectrometry and scanning electron microscopy with energy-dispersive analysis. A concentric ring structure of nodules with alternating zones rich in Fe and Mn has been revealed. Nodules act as geochemical barriers and accumulate not only iron and manganese, but also Cu, Ni, Co, Zn, and Pb. Keywords: ALBELUVISOLS, STAGNOSOLS, FLUVISOLS, ORTSHTEIN, RORENSTEIN, GEOCHEMISTRY CONSTANTS, ATOMIC ABSORPTION SPECTROMETRY, SEM/EDS, FE AND MN DISTRIBUTION, RING MICROSTRUCTURE
