Chemical characteristics of aerosol loads on PM episodes were investigated. Higher soluble ions concentration was observed on haze days while higher metals were measured on dust storms. SO42− was the most abundant chemical component of PM episodes. Aerosol is more acidic on haze days due to more secondary species formation. Aerosol from straw rice combustion showed high K+ and Cl−.
