| Also Known As | O₃, trioxygen, activated oxygen, ozone (allotrope of oxygen) |
What is Ozone?
An allotrope of oxygen with molecular formula O₃. Ozone in the stratosphere absorbs harmful UV radiation, protecting life on Earth. At ground level, it is a pollutant and respiratory irritant. Ozone is a powerful oxidizing agent used in water purification and bleaching.

An allotrope of oxygen with molecular formula O₃. Ozone in the stratosphere absorbs harmful UV radiation, protecting life on Earth. At ground level, it is a pollutant and respiratory irritant. Ozone is a powerful oxidizing agent used in water purification and bleaching.
Ozone is used in: water purification (disinfection more effective than chlorine, no halogenated by-products), bleaching of paper and food products, industrial oxidation reactions (ozonolysis of alkenes to carbonyl compounds), odour elimination, medical applications (ozone therapy, controversial), an…
Ozone is highly toxic at concentrations above 0.1 ppm (OSHA PEL = 0.1 ppm ceiling). It causes respiratory irritation, pulmonary inflammation, and exacerbates asthma. Ozone generators must not be used in occupied spaces. Ozone in industrial use requires gas detection, interlocks, and emergency ventil…
