(b)an aerosol is the site of many chemical reactions involving pollutants. Water surrounding the solid particle attracts airborne molecules that them readily react in aqueous solution before being released back into the atmosphereAerosol (烟、雾、气凝胶) and particulates facilitate chemical reactions involving pollutants Aerosol Fig 17.4 (a) micrograph of aerosols in the atmosphere.
