Abstract:
In this article influence of the Arselor Metall Steel enterprise on the condition of atmospheric air of districts
of the city of Temirtau, adjacent to the enterprise, is considered. The annual dynamics of the content of harmful
substances in the air reflecting the main tendency of increase of the indicators values in summer months,
mainly in July, decrease in September and repeated increase of values in November are shown. The main
substances polluting the air were defined: dust, nitrogen oxides, sulfurous anhydride, phenol, ammonia, carbon
monoxide, hydrogen sulfide. The analysis of the results showed that in the surface layer of the atmosphere
of the studied areas the concentration of sulfurous anhydride and hydrogen sulfide considerably exceeds
the standard values. According to the results of the research it was revealed that the region
OKZhETPES, the area DNTI and 117 quarter belong to the zones, which are exposed to the most intensive
negative impact, the quarter ABC belongs to the zone with the least pollution.
