The distribution pattern of 12 polycyclic aromatic hydrocarbons (PAHs) in the profile of the urbo–soddy–podzolic soil of the arboretum of the Botanical Garden of Moscow State University is studied. Several accumulative zones of PAHs are specified, the role of environmental factors in the accumulation of polyarenes at soil geochemical barriers is shown, the ecological role of contamination rates is evaluated, and probable sources of PAHs in soils are determined. Data on the share of polyarenes with pronounced carcinogenic properties in the PAH spectrum and their toxicity equivalent with respect to benz(a)pyrene are given.
