Abstract
The heterogeneity of the elemental composition of the soil cover and vegetation of the Altai-Sayan mountain country is due to the diversity and complexity of geomorphological, geological, hydrographic, and climatic conditions. The soils of the Altai-Sayan mountain country, which are not affected by the ore bodies of deposits and scattering halos, contain manganese below Clark, zinc - at its level, copper, cobalt, mercury-above. Abnormal concentrations of heavy mercury and cadmium were found in soils formed over mercury deposits. the Average concentration of chemical elements in plants, with the exception of manganese, is within the background values. does not exceed the maximum permissible level in feed, and the concentration of elements-toxicants-the permissible level for plant-based dietary Supplements. Plants-manganophils (representatives of the families Ericaceae and Vacciniaceae) can accumulate manganese more than 2000 mg/kg).
