Pollutants

• What is a major source of pollutants?

  The combustion of fuels
• What fuels contain sulfur carbon and/or hydrogen?

  Most fuels including coal
• how is Carbon dioxide produced

  Complete combustion in excess of oxygen of fuel containing carbon like coal crude oil(hydrocarbons)

  CH4 +2O2->CO2+H2O
• Carbon dioxide environmental impact

  Greenhouse gas too much can lead to global warming
• How is Carbon Monoxide (CO) produced

  Incomplete combustion (in limited supply of oxygen of fuel
• Carbon Monoxide (CO) environmental impact

  Toxic gas- combines with red blood cells (the haemogoblin in then and reduce the oxygen carrying capacity of blood
• How is Carbon (soot)/particulates produced

  CH4+O2—>C+2H2O
• Carbon (soot)/particulates environmental impact


  Global dimming

  Respiratory problems
• How is it sulphur dioxide (SO2) produced

  Fuel containing sulfur impurities like coal is burned

  S+O2->SO2
• Sulfur Dioxide (SO2) environmental impact

  Acid rain

  Destroys leaves and plants

  Corrodes limestone building

  Increases acidity of soil and lakes-kills fish

  Respiratory problems
• how is Nitrogen Oxides (NOx)or NO2 NO3 produced

  High temperature in car engine

  Nitrogen reacts with oxygen

  N2+O2—>2NO

  N2+2O2—>2NO
• Nitrogen Oxides (NOx)

  Acid rain

  Destroys leaves and plants

  Corrodes limestone building

  Increases acidity of soil and lakes-kills fish
