Abstract

Soils are an important component of polar ecosystems and play
a key role in their functioning. They have a significant role in processes of
accumulation, mobilization, redistribution of chemical, and especially, trace
elements in landscapes and ecosystems. Both anthropogenic factors and
climate change may affect biogeochemistry of soils in permafrost-affected
landscapes, which are considered as highly sensitive to climate change and
anthropogenic forcing. Involvement of additional portions of trace elements
into the soils due to permafrost degradation and thawing is considered as
one the main risk factors for natural environments in polar regions. Therefore, trace elements contents in soils of urban areas (Kharsaim, Aksarka,
Salekhard, Harp and Labytnangi) and natural environments of the Yamal
region (Ust’Uribey and Beliy island) were investigated. Soil samples from
Kharp settlement show the highest content for Cu, Pb, Zn, Ni, connected with
existing galvanizing plant “Kongor-chrome”. The highest values for Pb occur
in soil samples from Aksarka and Labytnangi key plots. Soil samples from
Kharsaim and Kharp key plots are characterized by the highest median values
for Zn. Analysis of trace elements content show poorly manifested eluvial-illuvial differentiation of soil profiles of natural soils. The highest content for
most of the studied trace elements has been revealed in topsoil horizons. Trace
elements content in soil samples collected from urban environments ranged
significantly high due to differences in the functional zones of the sites and
a predominant anthropogenic source of trace elements additions. The results
of statistical analysis show that statistically significant differences in Ni and
Cu content in soils appear only between Kharp settlement and each of natural
sites Ust’-Uribey and Beliy Island. Almost all studied urban soils reveal
significant differences in Pb, Zn, As, and Fe contents between natural sites.
