Presented are the data on quantitative content of polycyclic aromatic hydrocarbons (PAHs) in soils of the Khakassky nature reserve after the passage of forest and steppe fires. It is established that the composition of the background PAHs association includes fluorine, pyrenes, and naphtalenes. Once woody vegetation has burned out, the association involves benzo(ghi)perylene and tetraphene. Burnout of herbaceous vegetation is not conducive to changes in composition of the association identified in background areas.

Keywords: forest and steppe fires, protected territories, chernozems, soddy-calcareous soils.
