Study finds petrochemical industries behind winter ozone pollution
Wintertime ozone pollution in Lanzhou, China, is driven by alkene emissions from local petrochemical industries, with levels exceeding 100 ppbv. This occurs without sunlight and accelerates O3 production. Reducing alkene levels by 28.6% or nitrogen oxides by 27.7% could significantly curb O3 levels, highlighting the need for targeted actions in industrial regions.
