The behaviour of artificial radionuclides and microelements during forest fire events in the pine forests of the Altay Territory is investigated. It is shown that forestland burns are accompanied by active air migration of 90Sr,137Cs, Hg, Cd, As and other elements, and additional pollution of the components of forest biogeocenosis, at least at the areas adjacent to fire sites. The activity of element migration depends mainly on the biogeochemical characteristics of the elements, on the state of forest combustible materials, and on weather conditions. During the post-fire periods, redistribution of the elements occurs as a result of their transportation with melted snow water and rainwater. Revegetation carried out in burns promotes additional changes in element distribution over the burnt areas.
