"Ammonia (NH3) is a reduced nitrogen gas and is emitted in large quantities from\nanimal feedstocks, sewerage plants, etc. Ammonia is very soluble in water and\nis scavenged from the lower atmosphere by clouds. Ammonia is the most abundant\nalkaline gas in the atmosphere and plays a large role in neutralizing acidity\nfrom sulfuric and nitric acids via formation of the ammonium ion."^^ . .
