Abstract

The research objective was to assess the salinity of soils of an average city with a developed industrial production on the example of Gus-Khrustalny, Vladimir region. It was found that calcium cations and sulfate anions predominate in the studied soils. The increase in the content of individual ions has a local character associated with various sources of pollution. The excess of the maximum permissible concentration of nitrate ions by 1.1 times (145.05 mg/kg) is near the glass factory. The industrial zone of Gus-Khrustalny is characterized by contamination with toxic anions SO4 2–, NO3 –, as well as Mg2+ and K+ cations associated with the specifics of gas-air emissions of enterprises. Roadside areas are mainly contaminated with Na+ and Cl–, which come as part of deicing reagents. The most saline is the sample taken in the transport zone, characterized by a maximum content of Cl– (2819.5 mg/kg), SO4 2– (134.65 mg/kg), Na+ (2046.5 mg/kg) and a value of electrical conductivity (731.8 µS/cm). This study demonstrates that despite the significant impact of industrial enterprises, the primary source of salinization of the city soils is road transport.
