This study has a great practical and economic significance for regions with oil- contaminated soil. The concentration of oil products in the studied soil samples was determined by four methods: extraction from soil samples with n-hexane using a fluorescent photometric analyzer «Fluorat 02-3M LUMEX», carbon tetrachloride using an analyzer «AN-2», and chloroform using a gravimetric method. The data obtained make it possible to estimate the effectiveness of the application of the methods of analysis. There are also identified the advantages and disadvantages of direct and indirect methods for determining soil organic carbon, the effect of oil pollution on soil pH and carbon content in the soil. Evaluation criteria are proposed to improve the objective assessment of the state of oil-contaminated soils.
