Sources of Sulfur Dioxide and Oxides of Nitrogen

Identify natural and industrial sources of sulfur dioxide and oxides of nitrogen


  • The oxides of nitrogen are:
    • Nitrous oxide (N2O).
    • Nitric oxide (NO).
    • Nitrogen dioxide (NO2).
  • Nitric oxide and nitrogen dioxide are often collectively referred to as NOX.

Oxides
Natural sources
Industrial Sources

Sulfur dioxide (SO2)
  • Volcanoes
  • Geothermal hot springs



  • Combustion of fossil fuels (fossil fuels such as oil and coal contain sulfur)
  • Extraction of metals from sulfide ores


Oxides of nitrogen (NOX)
  • Lightening (lightening strikes produce very high local temperatures)
  • Geothermal hot springs.
  • Bacteria (act on nitrogenous material in soils)



Combustion (combustion chambers produce very high local temperatures)
