  1. 1. One could claim that Air Pollution started when humans began burning fuels or open-burning. In other words, all man made emissions into the air can be called air pollution, because they alter the chemical composition of the natural atmosphere.
  2. 2. Air Pollution is the introduction of particulates or other harmful materials into Earth’s Atmosphere.  Anthropogenic Sources (Man-Made)  Natural Sources
  3. 3. Construction sites produce a lot of dust Construction Sites
  4. 4. Releases the dangerous compounds Carbon Monoxide, Benzene, Lead, Dioxin and other Open Burning
  5. 5. Carbon monoxide gas from motor vehicle exhaust Motor Vehicle Exhaust
  6. 6. Ash from a volcanic eruption Volcanic Eruption
  7. 7. Release of smoke, Ash, Dust, Carbon dioxide, Nitrogen oxides Forest Fires by lightning
  8. 8. Windblown dust from areas with little vegetation Desert Area
  9. 9. An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. The substance can be Solid particles, Liquid droplets, or Gases.  Primary Pollutants  Secondary Pollutants
  10. 10. Pollutants emitted directly into the air. Primary pollutants are usually produced from a process.  Sulphur oxides (SOx)  Carbon monoxide (CO)  Nitrogen oxides (NOx)  Ammonia (NH3)
  11. 11. A chemical compound with the formula SO2 . Coal and petroleum often contain sulphur compounds, and their combustion generates sulphur dioxide.
  12. 12. Sulphur Dioxide (SO2) released from factories Sulphur oxides (SOx)
  13. 13. Petroleum combustion Sulphur oxides (SOx)
  14. 14. It is a product by incomplete combustion of fuel such as natural gas, coal or wood.
  15. 15. Natural gas is used for everyday cooking Carbon monoxide (CO)
  16. 16. Vehicular exhaust is a major source of carbon monoxide Carbon monoxide
  17. 17. Nitrogen oxides, particularly nitrogen dioxide, are expelled from high temperature combustion.
