The research objective was to assess the salinity of soils of the town of Melenki, Vladimir region, as a typical small city with a developed foundry. The ion content was determined by capillary electrophoresis. It was revealed that calcium is the predominant cation in soils, nitrates predominate among the anions. The excess of the maximum permissible concentration values in terms of anion content was not revealed. The soil sampled near the «Litmash-M» metallurgical enterprise is most polluted with phosphate and sulfate ions, which may be due to production emissions. The sample taken in the transport zone is characterized by maximum concentrations of potassium and sodium cations, probably coming as part of deicing reagents, as well as nitrate and phosphate anions, which is associated with motor vehicle emissions. Soils characterized by maximum values of specific electrical conductivity do not pose any danger to the vegetation of urban plantations due to the predominance of calcium and magnesium ions, which are essential trace elements for plants. The study demonstrates that despite the anthropogenic load due to the impact of the foundry, the soils of the town of Melenki are characterized by low salinity, which does not pose a danger to the vegetation of urban plantations.
