Abstract:

The article presents the results of tests performed on soil samples collected along the express
road running across the city center with various types of land development. The purpose of this
monitoring-oriented research paper was to analyze the sorption properties, the pH, the pollution
with petroleum-derived compounds, and the content of heavy metals Cu, Pb, Zn, and Ni in the
analyzed soil. In addition, it was assessed whether the area used by students as a research area
does not pose a health risk. The granulometric composition was also discussed. The obtained
test results indicate a comparable soil pH at the alkaline level with average organic carbon content
in the range of 1.05%–2.36%. The studied soils are characterized by the largest percentage
of coarse sand (0.63:2.0 mm) and medium sand (0.2:0.063 mm), the average iodine value indicates
soils of average sorption. Infrared spectroscopic studies allowed us to assess the content of
non-polar aliphatic hydrocarbons in the soil of the studied areas. These values are in the range of
8.34–42.05 mg/kg and were not exceeded in relation to the maximum values allowed in OJ.165.1359.
The percentage of the analyzed heavy metals in relation to the binding maximum content specified
in OJ.165.1359, was in the following order Pb > Cu > Ni > Zn.
