Abstract:The article represents the analysis results of the total elemental composition, pH values, and hydrolytic acidity of the soil samples collected from 6 sites in the basin of Messoyakha River (north-eastern part of Yamal-Nenets Autonomous Area). Сlarke of concentrations and enrichment coefficients are calculated to estimate the regional biogeochemical features. Reaction in gley сryosols and podburs (entic podzol) is varying from acidic in the upper part of the soils to neutral at the deeper layers, reaction in the alluvial soils is neutral. The elemental composition is varying depending on the bedrock particle size. In sandy podbur, soil values of accumulation coefficients (сlarke of concentration) are varying from 0.19 (Zn) to 0.66 (Mn, Pb), in a loam soil (alluvial and gley cryosols) — from 0.2 (Zn) to 0.96 (Pb). The average value of the enrichment coefficient is very low (R = 0.50). Thus, biogeochemical situation in the surveyed area is unfavourable; there is a significant shortage of zinc, copper, nickel in the soils. The maximum reserves of trace elements in the surface layer (0-20 cm) are observed in the alluvial soils, the minimum — in oligotrophic peat soil and podburs. Biogeochemical characteristics of the soils need to be considered when planning the recultivation and in the study of factors affecting the population health.
