Contamination of soils with polycyclic aromatic hydrocarbons near petrol stations in the city of Kielce

Petrochemical-derived products may enter the soil with rainwater, sewage, and during equipment failures. Due to their physicochemical properties, they cause a threat to the environment and change the properties of engineering-geological land. In the study, samples of soil originating from the vicinity of 20 gas stations in the city of Kielce have been examined. The following soil parameters were determined: pH, Hh, exchangeable cations, content of CaCO₃, Corg and PAH. The amount of PAHs and their composition varied depending on numerous factors such as the soil quality as well as location and degree of exploitation of petrol stations.
