Abstract

Oil-contaminated zones of small-river watersheds of the Middle Ob region in the areas of the Sovetskoe, Maiskoe, and Festival’noe oilfields of Western Siberia have been investigated. The contamination level was 29–60 g/kg versus 1.8 g/kg for the background. The polluting oil has been found to contain acyclic and aromatic hydrocarbon entities, of which pyrenes, chrysenes, and benzanthracenes are the most toxic. The specific runoff of oil products and their total annual inflow to the river system have been calculated using data of laboratory research, Landsat satellite images, and the software suites ASTER GDEM and SRTM.
