Short summary
Particle uptakes of HCHO and the impacts on PM2.5 and O3 production remain highly uncertain. Based on the investigation of co-occurring wintertime O3 and PM2.5 pollution in a coastal city of southeast China, we found enhanced heterogeneous formation of hydroxymethanesulfonate (HMS) and increased ROx concentrations and net O3 production rates. The findings of this study are helpful to better explore the mechanisms of key precursors for co-occurring PM2.5 and O3 pollution.
