Transformation of the organic background of the hydrosphere in conditions of oil pollution

Abstract

The methodological features of assessing the nature of organic pollution of the hydrosphere in oil-producing regions are considered. It has been established that in many cases the elevated values of the oil products indicator are due to the peculiarities of the natural hydrogeochemical background and are not associated with technogenic pollution. Using the example of oil fields in the Perm Kama region, it has been shown that reliable identification of sources of organic pollution is possible based on the study of the composition of aquabitumoids and water-soluble oil products by chromatography-mass spectrometry using the technology of spectral-chromatographic profiling.
