Scientific Approaches to Rationing of Petroleum Contaminations of Soils

Abstract

There were considered approaches to the development of standards of permissible residual oil content (SPROC) and certain petroleum fractions in soils. There was presented analysis of requirements SPROC in soils, developed for number subjects of Russian Federation (Republic of Komi, Khanty Mansysk District Yugra, Nenets Autonomous District, Republic of Tatarstan, Chuvashia Republic, Stavropol Kray, Tomsk Oblast, Krasnoyarsk Kray). There were revealed differences in regulatory values of permissible residual oil content and its transformation products into the same types of soils, characterized by the same sorption capacity, which indicates the absence of unified methodological approaches to establish requirements SPROC. There was offered methodology requirements development of SPROC in the soils, based on setting of quantitative and qualitative values in terms of soil condition in which the soil performs external and internal functions to ensure the preservation of the soil as the means of production, and avoid the negative impacts on the environment and human health. There was offered for setting of requirements for permissible residual oil and some of its fraction in soils on land category level is offered to use indicators that reflect likelihood of migrations of contaminants from the soil into components of environment. Petroleum products, oil hydrocarbons, soil, regulation, evaluation, soil function, intended use of land.
