Inorganic and organic peroxides have become the focus of increased attention by atmospheric chemists during the last decade. Hydrogen peroxide serves as an important link between gas phase radicals and aqueous phase chemistry in the atmosphere. As an important aqueous phase oxidant of S(IV), H2O2 plays a major role in the acidification of clouds, fogs, dew and rain. Several studies have indicated that peroxides and their precursor radicals cause damage to a variety of plant tissue.In this article we review analytical techniques, discuss and review the various sources of peroxides in the gas and aqueous phases and examine their reactions with S(IV) and N(III).
