The biogeochemical characteristics of the content of heavy metals in soil, plants and animals in different natural areas of Bashkortostan

• The content of heavy metals in the soils of Bashkortostan
• Determined the concentration of heavy metals in food plants in the area
• Established conversion factors of heavy metals from feed to animals
• Evaluate the impact of anthropogenic factors on the environment
• Heavy metal contamination of feed helps to increase their intake of horses.

The authors have investigated the process of migration of heavy metals from soil to plants and animals in the zone of influence of oil and ore deposits with the aim of biological indication of the state of ecosystem and assessment of ecological safety of production of animal products in different agricultural areas of Bashkortostan. The authors have made a careful study of the central part of the republic with dominant agricultural complex as a background territory.
