Witch'S brooms" As a result of anthropogenous impact on biological objects

Work is devoted to the analysis and studying the main anthropogenous factors influencing on biological objects of the urbanized territory of Kola North. Need of studying the influence of radiating factors on a state of environment, in particular studying the reasons of emergence in mass quantity of trees with the broken branching of crone (a big congestion of "witch's brooms") is revealed and proved. It is established that the soil of studied areas contains insignificant quantities of alpha, beta and active substances (uranium-238, radium-226, thorium-232, potassium-40) which can influence on physiological and biological characteristics of vegetation. The question of studying the influence of pollutants on formation of "witch's brooms" continues to remain debatable.
