o·zone
(ō′zōn′)n.
1. An unstable, poisonous allotrope of oxygen, O3, that is formed naturally in the ozone layer from atmospheric oxygen by electric discharge or exposure to ultraviolet radiation, also produced in the lower atmosphere by the photochemical reaction of certain pollutants. It is a highly reactive oxidizing agent used to deodorize air, purify water, and treat industrial wastes.
2. Informal Fresh, pure air.
[German Ozon, from Greek ozon, neuter present participle of ozein, to smell.]
o·zo′nic (ō-zō′nĭk, ō-zŏn′ĭk), o′zon′ous (ō′zō′nəs) adj.

o•zone
(ˈoʊ zoʊn, oʊˈzoʊn)n.
1. a form of oxygen, O3, produced when an electric spark or ultraviolet light passes through air or oxygen, that in the upper atmosphere absorbs ultraviolet rays, thereby preventing them from reaching the earth's surface, but that near the earth's surface is a harmful irritant and pollutant: used commercially for bleaching, oxidizing, etc.
2. ozone layer.
3. fresh air.
[< German Ozon (1840) < Greek ózōn, present participle of ózein to smell]

o·zone
(ō′zōn′) A poisonous, blue form of oxygen that has three atoms per molecule rather than the usual two. It is produced by electricity passing through air, as in a lightning strike, and also by the sun's radiation reacting with ordinary oxygen or with the pollutants in smog. Ozone is used commercially in water purification, in air conditioning, and as a bleach.
Did You Know? For the Earth's organisms, including people, ozone can be a lifesaver or a threat to health, depending on how high it is found in the atmosphere. The ozone that lingers in the lower atmosphere is a pollutant and contributes to respiratory diseases like asthma. But in the upper atmosphere, ozone protects us from the more severe forms of the sun's radiation. The region of the atmosphere in which ozone is most concentrated is known as the ozone layer, which lies from about 10 to 20 miles (16 to 32 kilometers) above the Earth. Because ozone absorbs certain wavelengths of harmful ultraviolet radiation, this layer acts as an important protection for life on the Earth. In recent years the ozone has thinned or disappeared in parts of the ozone layer, creating an ozone hole that lets in dangerous amounts of ultraviolet radiation. Ozone holes are created in part by the presence of certain industrial or commercial chemicals released into the atmosphere.
