The issue of soil pollution has become a global concern due to the extensive and accelerated industrial development since the Industrial Revolution. Various anthropogenic activities, including industrial processes and agricultural practices, introduce pollutants into the soil. These pollutants vary widely in type and concentration, and they pose significant risks to both the soil ecosystem and the surrounding environment. This study is part of an extensive series of laboratory investigations aimed at examining how different pollutants—specifically hydrocarbons, detergents, and pesticides—affect the geotechnical properties of clayey soils in Hungary. The primary focus of this research is to analyze the changes in the Atterberg limits of these soils when exposed to different pollutants. The laboratory tests were conducted in strict accordance with Eurocode standards to ensure the reproducibility of the results and consistency in the experimental procedures. The findings elucidate the distinct impacts of various pollutants on the Atterberg limits across different types of clay. The insight gained from this research can significantly enhance the efficiency, safety, and cost-effectiveness of geotechnical engineering projects.
