ECOLOGICAL ASSESSMENT OF SOIL HYDROCARBON POLLUTION BY MEASURING MAGNETIC SUSCEPTIBILITY

In this work, the magnetic susceptibility () of soils in situ was measured on the Pirallahi Island Oil Area. Pirallahi Island Oil Area is located near the Absheron Peninsula of Azerbaijan (Fig.1). In order to compare the results of measurements of the magnetic susceptibility of hydrocarbon (HC) -contaminated soils in situ, the ones of the HC of the hydrocarbon-free Dubendi site located on the mainland were also carried out. As a result of comparison of χ measurements, a difference in readings was revealed in both areas. Thus, the influence of hydrocarbons on the change in magnetic susceptibility measured on two similar areas is obvious. This clearly indicates a change in the association of magnetic minerals in soils exposed to hydrocarbons. It follows from the above that, using measurements of the magnetic susceptibility of soils in situ, we can detect areas contaminated with hydrocarbons. In the future, when using magnetic susceptibility and other magnetic parameters measured in bottom sedimentary rocks, they can be used as a new search feature for oil and gas deposits
