Abstract—Regularities in the formation of the pool of priority polycyclic aromatic hydrocarbons (PAHs) in
the soil–plant systems of the northern taiga forest biocenoses were revealed. In soils and plants, PAHs mainly
consisted of 3- and 4-nuclear structures. The content of polyarenes in plants on technogenically contaminated
areas exceeded the background values by 2–5 times. The maximum bioconsumption of polyarenes was
observed for bilberry leaves and Siberian spruce sprouts 4–5 years old. The highest mass fraction of PAHs was
found in Siberian spruce plants of a mixed spruce–birch forest of the northern taiga. It was revealed that bilberry
plants are hyperaccumulators of light PAHs.
