Short summary
Secondary inorganic aerosols have an important contribution to PM2.5. Based on 3 years of atmospheric observation data, this study systematically analyzed the pollution levels and chemical conversion characteristics of nitrate, sulfate and ammonium in PM2.5 in Chengdu, southwest China, and analyzed the emission and regional transport characteristics of their gaseous precursors. This conclusion can provide an important reference for the current air pollution control.
