Atmospheric Chemistry of Oxygenated Volatile Organic Compounds: Impacts on Air Quality and Climate

International audience; It is hard to overstate the importance of oxygenated organiccompounds in atmospheric chemistry. Oxygenated organiccompounds are emitted into the atmosphere from natural andman-made sources, and they are formed in the atmosphere asoxidation products of all hydrocarbons present in theatmosphere. Oxygenated volatile organic compounds(OVOCs) are generally more reactive than the alkanes fromwhich they are derived. OVOCs play an active role in thesequence of chemical reactions responsible for troposphericozone formation in both polluted and remote environments.
