4.11 Gas pollution

4.11 Understand the biological consequences of pollution of air by sulphur dioxide and by carbon monoxide.






Carbon Monoxide:
  • Caused by burning of fossil fuels and coal with insufficient oxygen 
  • Is very to toxic to living things especially humans 
  • Bonds with the Hemoglobin in the red blood stream and causes oxygen depletion in the blood stream
When fuels are burnt toxic gases are produced
Sulphur dioxide:

  • Is caused by the burning of coal and oil from factories 
  • Sulphuric acid forms acid rain (changes the ph of the water)
  • Causes plants leaves to burn and roots to be leached of minerals resulting in no growth 
  • Causes lakes to become acidic and reduces oxygen levels suffocating fish
