atmospheric pollutants

• carbon monoxide

  toxic gas that binds to haemoglobin in blood, preventing transport of oxygen
• how can the release of carbon monoxide into the atmosphere be reduced?

  by ensuring complete combustion of fossil fuels
• soot (carbon particulates)

  causes global dimming and lung damage
• how can the release of soot into the atmosphere be reduced?

  ensure complete combustion of fossil fuels
• sulfur dioxide

  dissolves in clouds to cause acid rain and causes respiratory problems
• how can the release of sulfur dioxide into the atmosphere be reduced?

  desulfurisation of petrochemicals before combustion
• oxides of nitrogen

  dissolves in clouds to cause acid rain and causes respiratory problems
