Abstract
This study investigates the environmental impact of oil contamination on soil properties in the Muradkhanli oil and gas field located in the Imishli region of Azerbaijan. The main objective of the research was to determine the levels of petroleum hydrocarbons and selected heavy metals in contaminated soils and to evaluate their ecological significance. Soil samples were collected from different points of the study area and analyzed using standard physicochemical methods and ICP-MS techniques. The results showed that petroleum hydrocarbon content ranged between 5.3% and 9.2%, indicating a high degree of contamination. The soil reaction was found to be slightly alkaline (pH 7.84–8.0). Although elevated concentrations of certain elements such as Zn, Cu, and Fe were detected, most heavy metals remained within permissible limits. The findings suggest that hydrocarbon pollution poses a significant environmental risk, while heavy metal contamination is relatively moderate. The study highlights the limited self-remediation capacity of contaminated soils and emphasizes the need for appropriate remediation strategies.
