Ammonia (NH 3) is the third abundant nitrogen-containing gas in the atmosphere, after N 2 and N 2 O (Seinfeld and Pandis 1998).As the primary alkaline gas in ambient air, NH 3 can neutralize nitric and sulfuric acid to form ammonium nitrate and sulfate (Pinder et al 2007), which are important constituents of airborne fine particles or PM 2.5 (Chow et al 1994).
