Ozone

Wikipedia ozone (uncountable)

(chemistry) An allotrope of oxygen (symbol O₃) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge; it is poisonous and highly reactive, but in the upper atmosphere it protects life on Earth from ultraviolet radiation.
(from an erroneous former belief that seaweed contains and releases ozone) Fresh air, especially that breathed at the seaside and smelling of seaweed.
- 1875, William Crookes, The Chemical News, page 99,
  
  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.
- 1888, L. T. Meade, A. Balfour Symington, Edwin Oliver, Atalanta, Volume 1, page 674,
  
  To Ramsgate baths she sped, in quest / Of seaweed and ozone ; / For seaweed and ozone were best, / They said, to give her tone.
- 2007, Robert Douglas, Tales of the Unexpected, Somewhere to Lay My Head, unnumbered page,
