Pronunciation

- /ə(ʊ)ˈzəʊn/ (Received-Pronunciation, obsolete)
- /ˈəʊzəʊn/ (Received-Pronunciation)
- /ˈoʊzoʊn/ (General-American)
Etymology
From German Ozon, coined 1840 by Christian Friedrich Schönbein, from Ancient Greek ὄζον (ózon), neuter participle of ὄζω (ózō, “I smell”), in reference to its pungent odour. The “fresh air” sense is from an erroneous former belief that seaweed contains and releases ozone.
Meanings
-

Martin said that the National Park Service invested in “a state-of-the-art ozone nanobubbler filtration system” that is intended to keep algae out.

(UK, informal, uncountable, usually) Fresh air, especially that breathed at the seaside and smelling of seaweed.
To Ramsgate baths she sped, in quest / Of seaweed and ozone ; / For seaweed and ozone were best, / They said, to give her tone.
1888, L. T. Meade, A. Balfour Symington, Edwin Oliver, Atalanta, volume 1, page 674:A patent obtained in England, and specified far from clearly, for obtaining ozone by boiling seaweed,†† may be mentioned as a curiosity, and also the credulity with which ozone-baths, prepared in this manner, find a ready sale, in spite of, or perhaps rather on account of, their high price.
1875, William Crookes, The Chemical News, page 99:It's got the lot: fresh sea air, ozone, seaweed. You could cut the air with a knife.
