Autoxidation of atmospheric pollutants

Proceedings of the National Academy of Sciences

Researchers report that organic peroxy radicals produced via the photodegradation of a prototypical atmospheric pollutant, n-hexane, undergo autoxidative pathways at ambient temperature, or spontaneous oxidation, at rates that suggest that autoxidation may become an important pathway for urban photochemistry across North America and lead to the production of organic hydroperoxides, findings with potential implications for air quality.
