The paper considers the data of experimental determination of more than 50 ingredients of gaseous and aerosol composition of air over the region of Nizhnevartovsk.
The pollution composition and distribution in the near—ground layer over the city and the vertical profiles of the impurities are determined. The diurnal variations of different air components are analyzed. The impurity budget is calculated over the region of the town and the Lake Samotlor oilfield. It is shown that three pollution sources act in the Nizhnevartovsk region in summer. They are the motor transport, plumes of combustion of the accompanying gases, and evaporation of petroleum products spilled on the underlying surface; the intensive photochemical processes in the urban air; and, the hydrocarbon sedimentation which is observed in the nighttime from the upper air layers. The impurity fluxes over the city and the oilfield are estimated.
