Study of the state of atmospheric air in the vicinity of non-ferrous metallurgy facilities and the power line tower damage

In the studies of the state of land areas performed using the advanced methods, in images from space, the industrial region around the city of Norilsk can be seen as a blurred spot that occupies an area of more than 900 km². Among diverse pollutants forming the picture, sulfur and nitrogen compounds, nitrates, sulfates, phenols, industrial dust, and heavy metals have a particular impact. The release of sour gases results in acid rains, which are among the major pollutants forming the whole picture. These substances affect humans, all objects of the environment, and sources of anthropogenic activities including engineering installations of power plant enterprises. The direct impact on the state of metal towers decreases significantly their lifetimes and increases the risk of emergencies. In this paper, the research data on the state of power line towers of different types are provided and the effect of acid precipitation on structures is shown.
