Kinetic and thermodynamic behaviour of volatile ammonium compounds in industrial and marine atmospheres

Autor: Rui M. Leal, Casimiro Pio, Teresa Nunes

Publikováno v: Atmospheric Environment. Part A. General Topics. 26:505-512

Measurements of volatile ammonium aerosol compounds and respective acidic and basic gaseous precursors were taken at an industrial site emitting HCl, HNO 3 and NH 3 and at a marine suburban location. Because of fresh industrial emissions the gaseous
