Polyarenes and Bitumoids from Analogous Technogenic Hydrocarbon Sources with Different Parameters in Soils

A study was done of soils in the Moscow, Omsk, and Samara oblasts subjected to hydrocarbon pollutant fluxes from industrial enterprises of the same production profile (carbon black plants) differing in (a) the type and environmental safety of production technologies, (b) the time of operation, and (c) the spatial location with respect to other possible sources of technogenic hydrocarbons. Polyarene and bitumoid geochemical fields in the impact zones of the enterprises were identified and investigated, and power functions reflecting the decrease in pollutant concentrations with increasing distance from the enterprises were determined. From the obtained functions, which are mathematical expressions for the generalizing vectors of hydrocarbon fields, their degrees of gradients were estimated. Polyarene associations and their localizations were determined using cluster analysis, and relationships of associations with the distance from the pollutant sources, the technological specialization of the enterprises, and the local factors of pollutant redistribution and transformation were revealed.
