Polycyclic aromatic Hydrocarbons (PAH) content in the peat of a palsa near Eletsky settlement (Bol'shezemel'skaya Tundra)
The total content of polycyclic aromatic hydrocarbons (PAHs) in the peat of a palsa near Eletsky settlement, Vorkuta urban district, Komi Republic, varies from 11 to 360 ppb, with an average of 63 ppb. Heavy compounds, such as benzo(a)anthracene and benzofluoranthenes, are prevalent among PAHs. Benz...
