  2. Ozone and biology - Wikipedia

    en.wikipedia.org/wiki/Ozone_and_biology

    Ozone in high concentrations is harmful to animals but they have been found to use small amounts of ozone. The immune system is thought to use ozonolysis by antibodies organizing 1 O 2 allowing H 2 0 3 to be produced.

  3. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    Ozone (/ ˈ oʊ z oʊ n /) (or trioxygen) is an inorganic molecule with the chemical formula O 3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 .

  4. Ozone layer - Wikipedia

    en.wikipedia.org/wiki/Ozone_layer

    The ozone layer peaks at 8 to 15 parts per million of ozone, [1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9 to 22 mi) above Earth, although its thickness varies ...

  7. Ozone depletion - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion

    Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, [citation needed] and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. [1] The latter phenomenon is referred to as the ...

    en.wikipedia.org/wiki/Ground-level_ozone

    Ground-level ozone (O 3), also known as surface-level ozone and tropospheric ozone, is a trace gas in the troposphere (the lowest level of the Earth's atmosphere), with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas.
