Gaseous and particulate products from the atmospheric ozonolysis of a biogenic hydrocarbon, sabinene

Résumé

This work investigates both the gaseous and particulate phase products from the ozonolysis of sabinene in smog chamber experiments. The gaseous phase was analyzed in situ by FTIR. The particulate phase was analyzed after sampling with a supercritical fluid extraction technique directly coupled to gas chromatography and mass spectrometry (SFE-GC-MS) and to an in situ derivatization method. Sabinaketone, formaldehyde, and formic acid have been detected in the gaseous phase. More than 30 products have been observed in the secondary organic aerosol formed from sabinene oxidation and among them 10 have been identified as compounds containing carbonyl, hydroxyl and carboxyl groups. Hypotheses concerning reaction formation pathways have been proposed for each identified product in gaseous and particulate phases.
