The paper presents the results of research on the content of selected heavy metals (Cu, Pb, Zn, Ni) depending on pH, organic carbon content and soil sorption in the direct location of busy streets around the campus of the Kielce University of Technology. Based on the conducted studies of the sequential fractionation of metals by the BCR method was found that the highest content of nickel fraction FI (exchangeable) was 142.75 mg/kg. However, the total nickel concentration in all research areas exceeded the value specified in the Journal of Laws approx. 2 times. The lowest content from the analyzed metals in the surface layer of soil was found for zinc, the content of which was 1.5% in relation to the standard. The average percentage share of the analyzed metals in the separated fractions, in relation to the total content, was in decreasing series for Ni: FIII > FI> FII> FIV; for Pb: FII > FI > FIV > FIII; for Cu: FII > FI > FIII > FIV and for Zn: FII > FIII > FI > FIV. The studied soils are characterized by a varied granulometric composition of sand fraction, from very thick (1000 μm–2000 μm) to very fine 2 μm–50 μm). Statistical calculations showed that the pH, Corg content and sorptivity of the studied soil correlate with each other.
