The IOA was formed in 1973 to serve as the focal point for technology transfer and developments on
ozone-related issues. For this purpose, IOA has served as the central , worldwide gathering and
disseminating point on ozone information, bringing together scientists, engineers, systems designers,
technologists, equipment manufacturers, and end users to share their experiences and research data on
ozone and other related oxygen compounds.
The IOA is a not-for-profit educational association which performs its information-sharing
functions through sponsorship of international symposia, seminars, publications, and the development of
personal relationships among ozone specialists throughout the world. Towards achieving this goal, IOA has
conducted a wide range of programs covering such fields as:
- Generation of ozone from air or oxygen by corona discharge or by ionizing radiation
- Mass transfer of ozone into water and wastewater
- Chemical reactions of ozone for commercial organic syntheses
- Drinking water treatment for disinfection and for oxidation of pollutants
- Ozone treatment for preservation of fruits and for food processing
- Stratospheric reactions of ozone
- Development of reliable analytical procedures for ozone
- Materials of construction for ozone use
- Ozone safety and health effects

members in North, Central and South America receive their membership services from and belong to the
Pan American Group [PAG].
All members in other countries of the World, excluding Japan, receive their
membership services from and belong to the European African Australasian Group [EA3G].
