Petroleum Hydrocarbons’ Content and Distribution in Soils of Geochemical Landscapes in Southern Sakhalin

Abstract

The article reports the results from the analysis of content and distribution of petroleum hydrocarbons in the soils of geochemical landscapes in southern Sakhalin. It discusses the main types of soil formed in this region and the parameters determining the migration of petroleum hydrocarbons in the landscapes. It has been shown that the soils of transit-accumulative and accumulative landscapes are characterized by the highest content and the penetration depth of petroleum hydrocarbons into the soil profile. In the event of accidental oil spills, along with lateral migration, a significant role is played by vertical migration of petroleum hydrocarbons to the accumulative landscapes.
