Abstrakt: The article studied the features of self-healing and self-cleaning of soils from oil pollution based on methods of chemical and toxicological analysis. The deviation of physiological reactions of plants sensitive to this type of pollution can serve as indicators of its condition. The essence of the study lies in the fact that the main physicochemical and toxicological indicators (germination of seeds, the average length of the root and shoots of seedlings and the average total length of seedlings) were analyzed in the oiled soil maintained during the year. Soil toxicity was determined under laboratory conditions. Wheat seeds were used as a test object. Studies conducted to analyze residual oil content indicate a decrease in the concentration of oil in the soil from 10 gr/kg to 4.5 gr/kg during the year, which is explained by the removal of the smallest components of oil from the soil - gaseous and volatile compounds. It was established that the residual concentration of oil in the soil changes the physicochemical properties of the soil extract, as well as negatively affects the growth and development of plants, which explains the low germination rates and average length in relation to the control soil.
