Ozone Diffusion Tubes

This tube is suitable for passive monitoring of Ozone (O3). Ground-level Ozone is not emitted directly but forms due to chemical reactions in the atmosphere involving hydrocarbons (C8 or lower), Nitrogen Oxides and sunlight. Therefore, hot summer days often lead to higher Ozone concentrations.


Sources of Ozone:

  • Natural sources.
  • Industrial emissions.
  • Vehicle exhausts.
  • Fuel vapours.
  • Solvents
  • Combustion processes.


Potential implications of Ozone pollution:

  • Respiratory irritation and reduced lung function, particularly in children.
  • Vegetation damage – leaf damage, reduced food production in commercial crops, increased susceptibility to disease.

Ground-level Ozone is regulated due to its respiratory health effects and vegetation effects. Monitoring should be conducted in areas of high precursor emissions or in areas at greatest risk of its damaging effects.

  • Outdoor air monitoring – roadside, industrial, natural process.
  • Environmental – forest management, crop production.
  • Traffic management.
  • Indoor air monitoring – migration of pollution into buildings.
  • Monitoring for health purposes, e.g. in schools, roadside, public buildings etc.
