Diagnostic ratios of individual polycyclic aromatic hydrocarbons for their identifiaction in soils of power station

Abstract

the article presents the study of the content of organic ecotoxicants-polycyclic aromatic hydrocarbons in the soils of the impact zone of the energy industry enterprise of Novocherkasskaya power plant (NPP)-the largest producer of electricity in southern Russia. The study showed a high level of total PAH content in the soils of the studied territory, compared to the background territories. The degree of contamination of soils in the zone of influence of the energy industry enterprises with Benzo(a)pyrene is classified as highly contaminated soils. The diagnostic relationships of individual PAHs showed a significant effect of the NchGRES on the soils of sites located along the line of the prevailing wind from NPP. For these sites, the pyrogen-coal origin of PAHs was established.
