Anthropogenic monoterpenes are worsening urban ozone pollution

This study was led by Prof. Keding Lu and Prof. Yuanhang Zhang from Peking University. They conducted a field campaign in Taizhou, Eastern China from May to June in 2018. They observed elevated levels of monoterpene, a formerly considered biogenic emitted Volatile Organic Compounds (VOCs), and determined a rapid oxidation rate by OH radical, O3 and NO3 radical observed with in-situ state-of-art instrumentations. Such fast oxidation rate of monoterpene even exceeded that of isoprene, which was thought to be the dominant biogenic emitted VOCs.
