| Abstract: | The quantitative concentrations of 21 congeners of polychlorinated biphenyls and 16 priority polycyclic aromatic hydrocarbons
were studied in bottom sediments of the Usa River, the largest Pechora’s tributary, and its tributaries located in the central
part of Timan-Pechora petroleum province. In accordance with the classification of the regional and international standards,
the pollution degree of bottom sediments by organic compounds of those classes was evaluated. Pollution profiles were examined
and the character of the dominating source of polychlorinated biphenyls and polycyclic aromatic hydrocarbons for bottom sediments
in the region under study was identified. Key words: bottom sediments, polychlorinated biphenyls, profiles of polycyclic aromatic hydrocarbons, petrogenic, pyrogenic pollution
source. |
