Ecological-geochemical features of the trace elements distribution in arable soils and parent bedrocks in the conditions of slope relief

The contents of trace elements Mn, Cu, Pb, Zn, Cr, Ba, and Sr in soils and parent bedrocks in the conditions of sloping terrain of the river valley were studied. The comparison of their concentrations with the clarkes of soils and lithosphere, maximum permissible and approximate permissible concentrations, regional background concentration was conducte
