Atmospheric Pollutants

• 5 main pollutants produced by fuels:

  • Carbon Dioxide
  • Carbon Monoxide
  • Sulphur Dioxide
  • Nitrogen Oxide
  • Particulates
• Global Dimming: When particulates travel into atmosphere and reflects sunlight back into space
• What gas is produced from complete combustion?

  Carbon Dioxide
• What gas is produced from incomplete combustion?

  Carbon Monoxide
• How is Sulfur Dioxide produce in a vehicle?

  Oxidation of the sulfur impurities in fossil fuels
• How are Nitrogen Oxides produced in a vehicle?

  Oxidation of Nitrogen in the air at high temperatures
• Effects of the Pollutants:

  • Carbon Dioxide= Enhances Greenhouse Effect
  • Carbon Monoxide= Takes place of RBC in haemoglobin
  • Sulphur Dioxide= Dissolves in rain to form acidic rain
  • Nitrogen Oxides= Respiratory problems + acidic rain
  • Particulates= Respiratory problems + Global Dimming
