The article provides an analysis of the environment and atmospheric air state in the city of Murmansk, the largest city in the world, located beyond the Arctic Circle and belonging to the Arctic zone of the Russian Federation. The legislative base of Russian Federation in the field of environmental protection is also analyzed; special attention is paid to its imperfection in terms of the classification of industrial enterprises in certain categories of hazard in accordance with established criteria. As an example, the environmental problems of Murmansk are analyzed and the necessity of carrying out «summary calculations» (complex calculations of surface concentrations of pollutants taking into account the mutual influence of enterprises and vehicles on the quality of atmospheric air) is substantiated. The results of summary calculations allow us to make a detailed picture of the territorial distribution of maximum concentrations over the whole spectrum of harmful substances entering the atmosphere of the city. It has been established that the maximum permissible concentration for nitrogen dioxide and sulfur dioxide is exceeded over the entire territory of the city, which confirms the necessity of improving the efficiency of weather protection activities in Murmansk and the creation of monitoring systems and quality management of the city’s air basin. Also, the results of summary calculations can be a basis for developing recommendations on the establishment of specific legislative claims in the field of environmental protection in the Arctic zone of the Russian Federation, the center of the Murmansk Region being an example partly as the enterprises, the primary sources of «black coating» on the territory of the city of Murmansk, could be referred to the facilities of the first category by the impact on the environment.
