Identification of the state of the soil-plant systems on the RUDN-University campus (based on PAH concentrations)

The environmental state of soil-plant systems under the condition of technogenic pressure has been demonstrated on the example of the social significant territory in the city of Moscow – the campus of the RUDN University. The assessment is based on the analyses of the environmental fate of polycyclic aromatic hydrocarbons (PAH) in soil, roots and aerial parts of plants of bluegrass meadow: Naphthalene (Naph), Fluorene (Fluorene), Phenanthrene (Phen), Anthracene (An), Fluoranthene (Flu), Pyrene (Py), Chrysene (Chr), Benzo[a]anthracene (BaA), Benzo[a]pyrene (BaP), Benzo[b]fluoranthene (BbFlu), Benzo[k]fluoranthene (BkFlu), Benzo[ghi]perylene (Bghi), Indeno[1, 2, 3-cd[pyrene (IP), Dibenzo[a, h]anthracene (DBa). These pollutants are considered as geochemical markers and reflect quite detailed the integral state of soil-plant systems. As a result, the zones with relative prosperous and with critical state are identified. The connection between physicochemical characteristics (log Kow) of pollutants and their accumulation activity (concentration coefficients) is confirmed.
