Air Pollution

• Air Pollution means the undesirable presence of impurities or the abnormal rise in the proportion of some constituents of the atmosphere.
• General Sources:

  • Man-made toxic substances (produced mainly by human activities)
  • Natural Phenomena (such as volcanic eruptions, dust storms, and wildfires)
• Primary Sources:

  • Combustion of Fossil Fuels - coat and oil for electricity and road transport, producing air pollutants like nitrogen and sulfur dioxide.
• • Emissions from industries and factories - releasing large amount of carbon monoxide, hydrocarbon chemicals and organic compounds into the air.
• • Agricultural Activities - due to the use of pesticides, insecticides, and fertilizers that emit harmful chemicals.
• Effects on Environment:

  > It has a major impact on the process of plant evolution by preventing photosynthesis in many cases, with serious consequences for the purification of the air we breathe.
• > It also contributes to the formation of acid rain, atmospheric precipitations in the form of rain, frost, snow or hog, which are released during the combustion of fossil fuels and transformed by contact with water steam in the atmosphere.
• Effects on Global Warming:

  > Air Pollution is a major contributor to global warming and climate change. — abundance of carbon dioxide is one of the cause of greenhouse effect. Normally, the presence of greenhouse gates should be beneficial – absorbing the infra-red radiation. But the excessive concentration is the cause of the recent climate change.
• Effects on Human Health:

  • responsible for the deterioration of human health
  • a significant risk factor for human health conditions – allergies, respiratory and cardiovascular diseases (lung damage).
