摘要：

The studies were conducted in different parts of the Baikal Region in Southern Pribaikalia, Southwestern Transbaikalia, and Northern Pribaikalia. it was shown that the chemical element content depends largely on biogeographical conditions and varies slightly between different types of forest in the same geographical region. However, the most significant factor leading to an imbalance of most elements is the emission load. It is concluded that the investigation of element trends in assimilating organs of woody trees is an important link in the system analysis of the vital status of tree stands under natural conditions and on exposure to abiotic factors.
