The results of ecological researches in the Arctic zone of the Russian Federation (Purovski district of Yamal-Nenets Autonomous okrug) are presented. The characteristics of emissions in the atmospheric air in Ustpurovsk-Tazovsk (Samburg) and Purovsk geocreology areas (Tarko-Sale) are considered and also the surface concentration of harmful substances in atmospheric air is predicted. A calculation of dispersion of polluting substances in the atmosphere is made. Based on the obtained results the conclusions were drawn about exceeding of the maximum-permissible concentration in the air.

Abstract. The paper describes innovative approaches to ensure environmental safety in the production of hydrocarbon material in a permafrost zone. Studies the anthropogenic environmental factors, climatic and geographical and geological conditions of Purovskiy district of Yamalo-Nenets Autonomous Area (YaNAO). We consider the chemical characteristics of wastewater discharged into surface water objects, polluting emissions into the atmosphere. The conclusions of the environmental situation in Purovskiy and Ustpurovsk-Tazovskiy permafrost areas. Calculate the concentration of pollutants in the control section of the water object and the maximum ground-level concentrations of pollutants in the atmospheric air. The conclusions about the exceeding the maximum permissible concentration (MPC) in the atmospheric air for solids, carbon monoxide, nitrogen dioxide. Was examined the climatic conditions of the Far North. Correlational analysis was performed between human factors and temperature conditions of the northern territories, as well as between the climate and natural features cryological and disturbed permafrost soils.

A research and comparison of natural and damaged (due to the active development of oil and gas fields) permafrost soils in the Jamalo-Nenets Autonomous Okrug were carried out. The analysis was run of correlation between an average monthly temperature of air, an average monthly sum of precipitation, the weight humidity and the thickness of the seasonal thawed layer. The conclusions were drawn about a poor resistance of landscapes on the permafrost rocks to the anthropogenic interventions, which in its turn is accompanied by the cryogenic processes and unfavorable influences on the Extreme North biosphere.

The paper considers the chemical characteristics of wastewater discharged into the surface water bodies on synthetic surfactants (detergents), phosphorus, iron, sulfates, chlorides, ammonia nitrogen, nitrate, nitrite Purovsk district YaNAO. The concentration of pollutants in the monitoring section water for the purpose of comparison with the maximumallowable concentration was calculated. The correlation analysis between anthropogenic pollution of water resources and climatic conditions of permafrost regions was carried out.
