The paper is devoted to the development of an efficient scheme for analytical control of biogenic and oil hydrocarbons in bottom sediments using gas chromatography/mass spectrometry technique (GC/MS) without using toxic, expensive compounds and internal standards to acquire data of the depth of penetration of anthropogenic oil pollution and total contents of oil hydrocarbons (OHC). This testing scheme was performed for real objects with different environmental loads. Bottom sediment samples were taken in the Nizhnevartovsk District 30 km northeast from Nizhnevartovsk city. The study area is a series of lakes located in the territory of the Samotlor oil field in the West Siberian oil-and-gas province. The field is the biggest one in Russia. The deposit is the largest in Russia. Survey results of 28 oil-polluted water bodies allowed forming the scheme for carrying out analytical monitoring of hydrocarbons in bottom sediments, and also identifying a set of analytical parameters by which one can authenticate pollution of bottom sediments with oil and OHC, assess its level and composition characteristics, which in turn enables to receive specific data on the depth of penetration of technogenic oil pollution and the total content of hydrocarbons in bottom sediments.
