Biogeochemistry of organic pollutants in technogenic landscapes. Pollution of soils by polycyclic aromatic hydrocarbons (PAHs). Analysis of data on the accumulation and transformation of PAHs in the soil-plant system, as the most informative indicator of the state of natural and technogenic landscapes. Information about the main mechanisms of accumulation, transformation and migration of PAHs, carcinogenic and mutagenic to living organisms, in the soil-plant system on an example on the territory of Novocherkassk Power Station zone according to long-term monitoring. The digital soil mapping in the polluted areas. Development of pollution forecast model in the case of PAHs pollution. Scientific approach for selection of the actual methods of contaminated areas remediation. Selection of sorbents for the bioremediation of soils contaminated by PAHs. The approaches to effective methods of analysis for the extraction of PAHs from soils and plants. Traditional methods of organic pollutants analysis in environmental objects. Elaboration and approbation of new ecologically clean and effective methods of PAHs extraction from environmental objects: the history of the question, recent application of technology, advantages of the approach.
