- Abstract
The content of polycyclic aromatic hydrocarbons (PAHs) in soil and snow cover near the carbon black plants in Moscow, Omsk, and Samara regions was studied. The differences in the composition, bulk atmospheric deposition, and resources of PAHs in soils in key areas controlled by the production technology and the duration of the plant work were revealed. It was established that all key areas are characterized by lower modern delivery of PAHs in comparison with the activities of plants in the past. The highest amounts and the heaviest composition of PAHs were detected near a nonoperating plant, which previously had used an environmentally unfavorable tube technology. In all areas, the soils are characterized by a higher proportion of phenanthrene associations in relation to the snow; without account for phenanthrene in soils, the same PAHs dominate in the snow. The snow and soil PAH associations are the most similar near the operating plant.
