Аннотация: The article discusses the problems associated with the anthropogenic impact of the Severonickel plant on the environment in the Murmansk region of the Russian Federation. Due to the operation of this plant, sulfur compounds and metal-containing aerosols prevail in the structure of atmospheric emissions of the Murmansk region. In order to identify the main areas of impact of the Severonickel plant, snow samples were taken directly near the industrial site, as well as at points north and south of the plant, as well as in the city of Monchegorsk and its environs. The evaluation of the concentration of heavy metals was carried out in the ecological and analytical laboratory of the Department of Environmental Management and in the laboratory of atomic absorption of the Department of Landscape Geochemistry, Faculty of Geography, Moscow State University. The highest values of the index of total pollution with heavy metals of snow are observed at sampling points located 750-1000 m north of the industrial zone, as well as at the point located 2.5 km northeast of Monchegorsk, at the intersection of the Kola highway and the railway station highway. According to 2017, the reaction rim of influence of the enterprise can be traced much further south and north. If according to the data of 2019, the points with significant indices of total pollution are located 2.5–3 km to the north and south of the plant, then, according to 2017, the influence of production can be traced in the radius of 8–10 km. Most likely, this difference in indicators is due to the frequency of winds. In 2019, the transfer of pollutants was much less active.
