What is Ozone (O3)?
Ozone (also referred to as trivalent oxygen or saturated oxygen) is a powerful oxidizing agent. Ozone in outdoor air is photochemically generated from a mix of nitrogen oxides and volatile organic compounds. As the number of motor vehicles increase, ozone is becoming an increasing problem in developed countries at latitudes with large solar fluxes. Outdoor ozone levels can vary by two orders of magnitude with time of day, day of week and season.
Sources of Ozone found indoors
Outdoor source is the major source of ozone found indoors. Ventilation-
Ozone initiated chemistry
Ozone can also react with indoor organics (source: Soft woods; wood flooring including cypress, cedar, and silver fir boards; houseplants, cooking, perfumes, tobacco smoke, soiled clothing etc) to form short-lived organics (e.g. secondary ozonides, peroxyhemiacetals, α-hydroxy hydroperoxides)
Possible Health Implications of ozone and ozone initiated chemistry products
Long term exposure to high levels of ozone may result in permanent lung damage. Exposure to ozone and ozone initiated chemistry products can also result in cough and chest pain on deep inhalation and shortness of breath, eye, throat and nose irritation, increased sensitivity to airborne allergens and irritants, aggravation of asthma and higher susceptibility to respiratory infection.
