4.11 Gas Pollution Consequences


Notes


Sulphur dioxide (SO2)


 - Combustion of fossil fuels, coals, oils
      - Factories
      - Vehicles

--> Sulphuric acid (SO2 + H2O) = Acid Rain
     - Vegetation: Leaves 'Burned' , Root system leached of magnesium and calcium = no growth
     - Lakes: Reduces Ph (acidic), brings aluminium ions = Al causes mucus thickening in fish,
fish not able to take in enough oxygen (suffocates)

Carbon monoxide


- Combustion of fossil fuels, coals, oils, with INSUFFICIENT OXYGEN

--> Bonds with Hb in RBC = Carbaminohaemoglobin, blocks Hb from carrying oxygen
   - Reduces oxygen circulation, toxic.
