The problem of pollution of soil cover with oil hydrocarbons and ways to improve their ecological state

The article is devoted to the study of biogenesity and self-purification capacity of gray meadow soils of the Siyazan district contaminated with oil hydrocarbons and the search for ways to optimize the environmental situation. The results of laboratory modeling of the intensification of self-purification processes by introducing various additives and biopreparation are presented. The results showed that the introduction of ameliorants into contaminated soil both separately and together in a model experiment contributed to a decrease in the content of oil hydrocarbons in the soil by 17-62% compared to the control and an increase in the total biogenesity of soils. These biotechnologies can be used in bioremediation of oil-contaminated soils, which will reduce the environmental load on the soil cover of industrially oriented territories.
