Popis:	The behavior of artificial radionuclides and microelements during forest fire events in the pine forests of Altai krai is investigated. It is shown that forest fires are accompanied by active air migration of 90Sr, 137Cs, Hg, Cd, As, and other elements, additionally polluting components of forest biogeocenosis, at least, on the territories adjacent to the fire areas. The activity of element migration depends mainly on the biogeochemical characteristics of the elements, on the humidity 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 and rainwater. Revegetation on firest fire burn areas additionally changes the element distribution over the burnt territories.
