Short summary

Isoprene is the predominant non-methane compound emitted by the biosphere. In the atmosphere oxidation by OH under low NO_x produces isoprene hydroxy hydroperoxides (ISOPOOHs). This work has found an effective conversion of ISOPOOHs to volatile carbonyls on metal environmental simulation chamber walls. Likely catalyzed decomposition reactions also occur for other hydroxyl hydroperoxides on metal surfaces.
