摘要

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.Notes Translated from Pochvovedenie (2012) 3, 356-367 (Ru).
