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 .
Sea air has traditionally been thought to offer health benefits associated with its unique odor, which Victorians attributed to ozone.More recently, it has been determined that the chemical responsible for much of the odor in air along certain seashores is dimethyl sulfide, released by microbes.
However, because of the presence of Reaction 2 and 3, NO x and ozone are not in a perfectly steady state. By replacing Reaction 6 with Reaction 2 and Reaction 3, the O 3 molecule is no longer destroyed. Therefore, the concentration of ozone keeps increasing throughout the day. This mechanism can escalate the formation of ozone in smog.

Most people shouldn't be worried about exposure to temporary pollutants like smoke or exhaust in the air outside your home, as they dissipate over time, explains Ryan Roten, D.O., an emergency ...
Nitrous oxide has also been implicated in thinning the ozone layer. A 2009 study suggested that N 2 O emission was the single most important ozone-depleting emission and it was expected to remain the largest throughout the 21st century. [10] [134]

Geosmin (/ dʒ i ˈ ɒ z m ɪ n / jee-OZ-min) is an irregular sesquiterpenoid with a distinct earthy or musty odor, which most people can easily smell. The geosmin odor detection threshold in humans is very low, ranging from 0.006 to 0.01 micrograms per liter in water. [1]
