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 question of the approaching ecological catastrophe is becoming more and more urgent day by day.

Methods for calculating pollution and concentration factors
Instructions
Step 1
Human needs and desires grow more and more every day. This process is almost impossible to stop. Hundreds of thousands of factories for the production of various goods and for the processing of all kinds of fuel annually increase the volume of products and, as a result, the volume of hazardous waste into the atmosphere. On average, more than 190 million tons of carbon dioxide (carbon dioxide) enter the atmosphere of our planet per year. It is impossible to stop emissions, because our society is at a 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.
Step 2
The level of purification is determined by the value of the maximum permissible emissions, that is, the amount of pollutants emitted into the atmosphere, which will provide such a concentration in the surface layer of the atmosphere that does not exceed the maximum permissible coefficient of a given pollutant for a given territory. All methods of cleaning from fugitive emissions are subdivided into regenerative (allow the return of emission components to production) and destructive (transform components into less harmful ones).
Step 3
But do not forget that mobile sources of emissions make an equally significant contribution to air pollution. cars. The share of emissions from vehicles has increased by 40% over the past two years (from 2009 to 2011). Many environmental scientists identify the main ways to reduce environmental damage from transport, such as: optimization of urban traffic, the development of alternative fuel sources; creation (modification) of engines using alternative fuels.
Step 4
In order to avoid an environmental catastrophe, modern society must, if not completely exclude road transport, then minimize harmful emissions from it. Work on this issue is being carried out all over the world and is already yielding certain results. Cars currently produced in developed countries emit harmful substances dozens of times less than 10-15 years ago. In all countries, there is a tightening of control of harmful emissions during engine operation. There is both a quantitative tightening of norms and their qualitative change.
