Soil chemical properties are essential for the functioning of soils in the polar biome. This study aimed to evaluate ecotoxicological state of urban soils of Yamal region. At 17 sites 39 soil samples were collected and analyzed. Trace elements were detected with X-ray fluorescent analyzer “Spectroscan-MAX”. The values obtained were compared with the Approximate Permissible Concentrations and Maximum Allowable Concentrations adopted in Russia. The highest median values for Cu were found in Kharp, for Pb - in Aksarka and Labytnangi key plot, for Zn and Ni – in Nadym. Calculated p values for Cu, Zn, Ni, and Mn are lower than 0,05 significance level. Pb contents showed no significant differences. Statistically significant differences in Ni and Cu contents in soils were found only between Kharp and each of the rest settlements. Predicted Arctic warming will lead to degradation of permafrost, which could affect the rates of accumulation, transformation, translocation, leaching and transportation of trace elements and other pollutants within the permafrost-affected landscapes
