Ecology-geochemical estimation of oil degradation products under the hypergenesis condition

Бесплатный доступ

The article deals with results of detailed geochemical survey of bitumens of soil, contaminated by oil, and character of their transformation under hypergenesis conditions. Main directions of the oil compound transformation were explained. It was established that oil transformation under the hypergenesis condition leads to reforming hydrocarbons into the wide range of non-hydrocarbons compounds. Separation of oil degradation steps (-fresh‖, -mature‖, -old‖ pollution) identifiable by geochemical markers was offered. Products of oil transformation were sorted by ecological significance. Features of forming of water-solved oil complex were found out on the base of laboratory modeling of behavior -oil-water‖ system. Geochemical markers reflecting availability of oil components in water-solved organic composition were determined. Estimation of ecological significance of these compounds by reference to sanitation and hygiene regulations was performed. Oil behavior modeling in natural and laboratory experiments allows us to develop a scientific and methodological approach to monitoring oil pollution. This approach is strategically focused on the control of residual oil and oil degradation products in contaminated object, linked environments and contiguous territories.
