Ecological-geochemical assessment of the Surgut lowland.
The article deals with the evaluation of soil pollution within a large oilfield under bioclimatic and soil-geochemical conditions of the Surgut lowland and possible differentiation of its territory according to pollution effects. As a index plot was researched the area of Fedorovskoe oilfield. Methods of field, laboratory and cameral studies are discussed, as well as the resulting soil-geochemical parameters (lateral and radial distribution of oil products and heavy metals in soils, their migration and accumulation on various geochemical barriers, etc.) The results of the study are of practical importance.
