4 causes of air pollution

4 causes of air pollution

Transport and Communications 

  And is the source of 70 percent of the pollutants in the air, most notably carbon monoxide 

Nitrogen and hydrocarbon gases, and to lead material used 

in some types of motor fuel 

Thermal power plants 

  Private power generation, these plants use solid fuels (coal) or liquid fuel 

(FUEL) or gaseous, and during the process of combustion and power generation boilers are throwing these fuels in the form of a gas or parts 

Called small solid ash, causing air pollution, especially if the air filter is zero, either through by dry 

Or wet between boiler and flue

And mainly, biomass, electricity generation, which consumes about a quarter of the world's energy consumed in the quarter reflects the reason the amount of 

Pollution in the air, and the most important pollutants noteworthy, there are carbon dioxide, nitrogen oxide and   oxides 

 ( Sulfur. (  CO2 - NO2 - SO2 

First, solid materials suspended: like smoke, and exhaust A Car, and dust, pollen, dust and cotton, cement dust, dust and pesticides. 

Second: gaseous substances or toxic fumes and suffocating, such as chlorine, carbon monoxide, nitrogen oxide, sulfur dioxide, ozone. 

Third, bacteria and germs, and mold resulting from the decomposition of dead plants and animals and waste anthropomorphism. 

Fourth: Atomic radiation natural and industrial

 Industrial centers

   Consume a significant portion of the energy and be the cause of pollution, especially in industrialized countries 

P having produced water  ..industrial pollution channels streams and aquifers or surface and in the case of high 

Temperature evaporate into the air and  

Natural factors 

such as volcanic released into the atmosphere large amounts of gases and solids blazing 

And also of the dust and wind Trial they solve, especially in 

the desert areas and dry
