This paper presents data on the largest accidents associated with oil and petroleum product spills in the Re-public of Sakha (Yakutia). A comparative assessment of the condition of soils taken from the territory of a technogenic object (oil depot) and a natural object (forest lands) contaminated with oil products is given. It is shown that peculiarities of distribution and degradation of oil hydrocarbons depend on many factors such as: the volume of spilled oil products, their composition, period of occurrence and duration of exposure, type of soil, presence of permafrost, climatic features, etc. A comprehensive study of the peculiarities of oil hydro-carbons behavior in permafrost soils makes it possible to carry out scientifically based monitoring of the state of territories with high anthropogenic loads.
