Ecological Safe Concentrations of Oil in the Soils of the Black Sea Coast of the Caucasus

Environmentally safe concentrations of oil in the soils of wet and dry subtropics of the Black Sea coast of the Caucasus (Black Sea Coast) have been established according to the degree of violation of their ecological functions. The indicators of the number of bacteria, the activity of soil enzymes, plant growth and development were determined. Based on the analysis of the degree of disruption of the ecological functions of soils, regional values of the maximum permissible concentrations of oil in the soils of the Black Sea Coast have been established.
