The relevance of the research is related to insufficient volume of data on mercury content in soils and components of biosphere in the subtaiga subzone. Leaf litter is an important component of the biological cycle in boreal forests and the source of chemical elements entering the soil. The main aim is to reveal the regularities of mercury distribution in the leaf litter of mixed coniferous-deciduous forests in the natural territory. Object of researches is leaf litter of mixed coniferous-deciduous forests (subtaiga forests) in the natural territory. Methods: selection of trial plots, account for leaf litter, determination of mercury content in leaf litter. Results. The authors have studied mercury content in the leaf litter of the forests of the subtaiga zone under background conditions. The investigations were carried out in the southwestern part of the West Siberian lowland, in the Tarman lake-bog massif system, in the interfluve of the middle course of the Tavda and Tura rivers in the territory of the Tyumen Federal Wildlife Refuge. The leaf litter was taken at the registration sites, differing in the ratio of deciduous and coniferous tree species: birch-pine with a linden forest; fern pine with an admixture of birch; lime-birch forest. The authors determined the regularities of mercury content in leaf litter depending on the species composition of the woody plant-edificators. It is shown that leaf litter of lime-birch forest is characterized by the highest mercury content. The distribution of mercury is determined by the fractions of leaf litter (needles, leaves). Mercury distribution by leaf litter (needles, leaves) fractions is determined. It is shown that mercury content in the leaf litter fraction is higher than that in the coniferous one. The authors calculated mercury amount entering the soils of forest landscapes with leaf fall.
