However, the researchers discovered that, when the fluid is acidic--a pathological condition found in asthmatics--ascorbic acid instead reacts with ozone to form potentially harmful compounds ca]led
ozonides.
The literature shows that ozone attacks double bonds by formation of unstable
ozonides, which lead to the formation of carbonyl groups, preferentially acid groups (33).
Peroxides could be formed (23) and their decomposition (14) could result in the formation of carbonyls (22), carboxylic acids (24), ethers (22), hydroxyls (25), and
ozonides (22).
Examples include primary and secondary
ozonides, peroxyhemiacetals, [alpha]-hydroxy ketones, [alpha]-hydroxy hydroperoxides, and peroxyacyl nitrates (Atkinson and Arey 2003; Docherty et al.

Alcohols, carbonyls, and carboxylic acids enhance the formation of secondary
