Ozone | Definition, Properties, Air Pollution, Importance ...
Jan 23, 2025 · Ozone usually is manufactured by passing an electric discharge through a current of oxygen or dry air. The resulting mixtures of ozone and original gases are suitable for most industrial purposes, although purer ozone may be obtained from them by various methods; for example, upon liquefaction, an oxygen-ozone mixture separates into two layers, of which the denser one contains about 75 percent ...
Ozone | O3 | CID 24823 - PubChem
Ozone (O3) concentrations were measured from 1981-83 at each of three urban stations in the cities of Edmonton and Calgary and were compared with O3 values reported earlier in rural Alberta areas. Ozone concentrations in Alberta cities typically exhibit a max in May (up to 35 ppb) and a minimum in Nov (as low as 4 ppb).
