Abstract:
Polycyclic aromatic hydrocarbons (PAHs) have been a major concern because of their carcinogenicity, mutagenicity, teratogenicity and wide distribution in the environment. Over 90% of PAHs in the environment exist on soil surface/sediment. Thus, it is critically important to understand the patterns of BaP accumulation and transformation peculiarities in soil for the technologically polluted territories remediation. It was studied the soils contaminated by power energy enterprise working on the burning coal with over 70% emissions containing PAHs. The territory adjoined to the Novocherkassk Power Station showed an intensive accumulation of polyarenes increased from 2012 up to 2019. With increasing distance from the plant, the PAHs accumulation in soils gradually decreases. The maximum of the PAHs content in the soil was found on the monitoring site located at 1.6 km from the enterprise 4185.4 ± 167.4 ng/g, the lowest level of PAHs was found at 20 km (1185.5 ± 45.0 ng/g PAHs). PAHs extraction from collected soil samples was performed using new ecologically clean express-method of subcritical water extraction without organic solvents use. The approaches for improving the contaminated territory ecological situation have been proposed including biological remediation by biochar, activated carbon.
