Short summary

Synchronous online monitoring was performed in two urban sites and three rural sites in Henan Province. Results show that PM_2.5 was more acidic in urban aerosols than that in rural regions, and excess NH_x concentrations played a key role in the local particle pH values. Air masses transported from rural and agricultural regions may promote the sulfate formation in urban aerosols. Therefore, ammonia should be involved in the regional strategy for improving the air quality in China.
