Research Insights: Unexpected cause of winter ozone pollution

Prof. Guo's group have uncovered an unexpected phenomenon: severe wintertime ozone pollution in Lanzhou, China, driven primarily by alkene emissions from local petrochemical industries. [Full-text]. Based on observation data and a photochemical box model, this study identified alkene ozonolysis as the dominant driver of ozone formation, rather than the traditional radical sources initiated by photolysis. The findings complement conventional views on ozone pollution and call for targeted action in industrial regions.
