Environmental safety of the territory in the gas station zone

Abstract

The article deals with the problem of ecological safety and ecological diagnostics of soils in the gas station zone located in the center of the city of Irkutsk. The factors of disruption of natural properties when polluted with oil products have been investigated. The physicochemical parameters of soils, integral indicators of the state have been analyzed, the violation of their natural properties has been revealed, the composition of the surface runoff from the object has been studied. Technogenic halos of oil products spreading outside the source of supply on the basis of GIS were obtained, the accumulation of oil products in the soil up to a distance of 250 m from the filling station was revealed. The results of the dynamic behavior of petroleum products, the methods of ecodiagnostics used can be the basis for determining the direction of the soil distribution of pollutants outside the hazardous facility. The sampling system around fuel stations will make it possible to build GIS maps of technogenic oil pollution fields and develop preventive environmental protection measures. The results obtained are of practical importance for the environmental management of the city, for the cadastral valuation of land, for adjusting the placement of transport routes and the network of gas stations.
