Pollutants in Air

• Polultant: Carbon monoxide (CO)

  Source: Incomplete combustion of carbon-containing substances (ex. Internal combustion engines)

  Negative Impact: Binds with haemoglobin, constricting oxygen supply in cells; leads to fatigue/ death
• Pollutant: Sulfur Dioxide (SO2)

  Source: Hydrocarbons burned with sulfur impurities/compounds (ex. Fossil fuels)

  Negative impact: Causes acid rain and bronchospasm in asthmatics
• Pollutant: Nitrogen Oxides (NOX)

  Source: High temperatures that trigger a reaction between N2and O2(ex. Car engines)

  Negative impact: Causes respiratory problems, photochemical smog; contributes to acid rain
• Pollutant: Lead Compounds

  Source: Combustion of leaded fuels

  Negative Impact: Damages brain and nerve cells in young children
