Short summary

The increasing concentration of O₃ precursors and unfavorable meteorological conditions are key factors in the formation of O₃ pollution in Zhengzhou. Vehicular exhausts (28 %), solvent usage (27 %), and industrial production (22 %) are identified as the main sources of NMVOCs. Moreover, O₃ formation in Zhengzhou is found to be in an anthropogenic volatile organic compound (AVOC)-limited regime. Thus, to reduce O₃ formation, a minimum AVOCs / NOx reduction ratio ≥ 3 : 1 is recommended.
