This review paper is devoted to polycyclic aromatic hydrocarbons (PAHs, arenes), high molecular organic compounds, in the structure of which benzene rings are present. PAHs are considered to be priority pollutants, since many of them possess carcinogenic and mutagenic activity and pose a danger to human health. The paper discusses the technologies for the removal of PAHs from the environment, in which bioremediation is one of the most promising and safest options. Various genera of bacteria, fungi and algae that are capable of highly efficient biodegradation of PAHs are characterized. In addition, the review discusses the extent and mechanisms of action of PAHs on various components of the environment. The information is provided on the main sources of PAHs, role of abiotic and biotic factors in the biodegradation of PAHs in the environment, and mechanisms for the degradation of PAHs by microorganisms are considered.
