Air Pollution

    air pollution
Is the presence of any solid, liquid or gaseous air quantities lead todamage to physiological, economic and vital to humans, animals and plants, machinery, equipment, or influence the nature of things andestimated loss of the world each year by about 5000 million dollars,due to the impact the air, on crops and agricultural plants.

    Methods of air pollution:
First, solid materials suspended:
Smoke and car exhaust, dust, pollen, dust and cotton, cement dust,dust and pesticides.

Second: The gaseous material 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. 
  
  Causes of air pollution are: -
Transport and communications of all kinds
Stationary combustion centers
Centers and industry groupings
Natural factors

   This adverse impact of air pollution has led many governments, associations and international organizations and civil, and sometimes under the pressure of public opinion, to take steps and measures aimed at reducing air pollution, and thus control of thecenters of this pollution and sources of all types, have shown the overall studies and measurements made in various parts of the world that most of the air pollutants produced from combustion processes used in various industrial sectors in addition to the transport sector, and combustion processes is the traditional means of energy conversion from one condition to another, specifically from the thermal energy stored within the fuel to the energies ofmechanical, electrical and others.

We have deliberately industrialized countries to develop a series of actions and measures conducive to the mitigation of air pollution.
