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.

The resistance of polymer composite materials to external environments including fungi, bacteria and yeasts is a key factor in their reliability. These microorganisms, known as degraders or biodegraders, are capable of causing biological damage and even complete destruction of composite materials by altering their structure and functional characteristics.
