Forest litter is the most significant component of forest biogeocoenosis for the studies of the behavior of chemical elements and artifical radionuclides during forest fire events. The ubiquitous distribution of forest litter, active biogeochemical processes that occur in it due to permanently incoming organic matter, high depositing properties with respect to chemical components preciрitated from the atmosphere align forest litter as the natural objects playing an exclusive role of biogeochemical barrier at the routes of element migration in forest ecosystems. Investigation of the distribution of chemical elements in forest litter and the degree of its burning out during forest fires allow us to distinguish a group of elements that migrate from the sites of fire and to determine the degree of their carry-over quantitatively.
