Standards of admissible residual content of oil and products of its transformation in soil in the Perm region and other regions of Russia

The article provides an overview of the regional standards for the permissible residual content of oil and its transformation products (DOSNP) in the soil after reclamation works in the Perm Territory and other regions of Russia. Regulatory acts establishing standards in the regions of Russia are given. At the moment, the standards of DOSNP are established in the following regions: the Republic of Udmurtia, the Khanty-Mansi Autonomous Area - Yugra, the Nenets Autonomous Region, the Republic of Tatarstan, the Komi Republic, the Chuvash Republic, the Perm Territory. In the Perm Territory, the DOSNP standards are established for agricultural land and forest land, for the following soil types: sod-podzolic, mostly deep podzolic; podzols illuvial-ferruginous (podzols illuvially-low-humus); peat bog riding. Based on the analysis of the standards developed for the subjects of the Russian Federation, it can be said that the standards of DOSNP for the Perm Territory are among the lowest. Higher standards in the Perm Krai are established only for peat soils (5.3 g / kg) on agricultural land, which is justified by the fact that these soils are characterized by a natural content of hydrocarbons. Values for other soil types are significantly lower than those established in other regions.
