### Physicochemical Properties of Soil Subjected to Pressure from DO and G  
An important research step in assessing the condition of soils exposed to DO and G pressures was to track changes in soil physicochemical properties (Tables 4 and S1). Diesel oil (DO) exerted greater pressure than gasoline (G) on the physicochemical properties of the soil (Table 4). In the soil not modified by sorbents, DO increased the content of C\({}_{\text{org}}\) from 7.10 g to 10.19 g kg\({}^{-1}\) of soil, N\({}_{\text{total}}\) from 1.12 to 1.27 g, C:N ratio from 6.34 to 7.99, pH value from 4.30 to 4.90 and decreased HAC from 35.25 mmol(+) kg\({}^{-1}\) of soil to 27.87 mmol(+) kg\({}^{-1}\) of soil. It did not change the values of EBC and CEC but caused an increase in BS from 54.17% to 64.4%. A similar direction of DO effects was observed in the soil with the addition of perlite, while the implementation of dolomite contributed to an increase in soil pH, EBC, CEC, and BS in all treatments, and decreased HAC. The above changes were more strongly determined by the application of dolomite than by DO. Gasoline induced minor changes in the values of the studied parameters (Table 4). These changes were limited to a decrease in the content of C\({}_{\text{org}}\) and an increase in the
