Industry in our time is developing very actively and determines the pace of development of modern society.
However, the rapid growth of production had a negative impact on the state of the environment, so the issue of approaching an environmental disaster day by day becomes more urgent.

- Techniques for calculating pollution coefficients and concentration
The needs of man and his desire to grow fromEvery day more and more. This process is almost impossible to stop. Hundreds of thousands of factories for the production of various goods and for the processing of various types of fuel annually increase the volume of manufactured products and, as a consequence, the volume of harmful waste to the atmosphere. On average, over 190 million tons of carbon dioxide (carbon dioxide) enter the atmosphere of our planet over the year. It is impossible to stop emissions, because Our society is at that stage of development, when we are completely dependent on conveyor production and oil refining. Therefore, it is necessary to improve the cleaning system at the enterprises themselves.
The cleaning level is determined by the amountThe maximum permissible emissions, that is, the number of pollutants emitted into the atmosphere, which will ensure such a concentration in the surface layer of the atmosphere that does not exceed the maximum permissible coefficient of this pollutant for the given territory. All methods of purification from fugitive emissions are subdivided into regenerative (allow to return emission components to production) and destructive (transform the components into less harmful ones).
But do not forget that no less contributionIn the pollution of the atmosphere make and mobile sources of emissions, i.e. Cars. The share of emissions from motor vehicles increased by 40% in the last two years (from 2009 to 2011). Many environmental scientists identify the main ways to reduce environmental damage from transport, such measures as: optimization of urban transport, development of alternative sources of fuel - creation (modification) of engines using alternative fuels.
In order to avoid environmental Catastrophe, Modern society needs, if notCompletely eliminate road transport, then minimize harmful emissions from it. Work on this issue is being conducted around the world and is already yielding certain results. Cars that are currently produced in developed countries throw out harmful substances ten times less than 10-15 years ago. In all countries there is a tightening of control over harmful emissions when the engine is running. There is a quantitative tightening of norms, and their qualitative change.
