Abstract
In this article, we investigated the gaseous emission dynamics of Sverdlovsk region chemical complex from 2011 to 2015. We have analyzed the dynamics of changes in the atmospheric air state in cities where the big chemical enterprises are located. Our main attention is paid to gases emissions such as carbon monoxide, nitrogen oxides and sulfur dioxide. We also looked at the volume of purified gas emissions in all gaseous emissions from the chemical industry enterprises. The contribution of emissions from chemical industry is relatively low and accounts for approximately 4 % of emissions from all manufacturing industries, including metallurgical complexes. There is a general tendency to reduce emissions of pollutants in connection with the implementation of environmental measures. Reducing the gaseous substances emission can be achieved both by improving the production technology, and by installing new more sophisticated equipment which catches harmful substances emissions.

The state observation organizations carry out data acquisition on environmental pollution during the monitoring of pollutions [10, 11]
We have analyzed the data of state reports on air pollution in those Sverdlovsk region cities where chemical enterprises are located
Summary
At the beginning of the 20th century man's anthropogenic influence was not as high as at the beginning of the 21st century. During one hundred years the economic activity of man has so strongly influenced on the state of the environment that it can lead to irreversible changes of the future destiny of humankind. Excessive emissions into the atmosphere, dumping into the hydrosphere, solid waste disposal in the lithosphere are resulted in such negative consequences as: greenhouse effect, smog, acid rains, significant excess of TLV (threshold limit value) of many dangerous substances in places of people's lives, etc. Human society is trying to solve environmental problems that have created for ourselves, in order to live and not survive on the Earth [1,2,3]
