Química atmosférica do enxofre (IV): emissões, reações em fase aquosa e impacto ambiental

Abstract

ATMOSPHERIC CHEMISTRY OF SULFUR (IV): EMISSIONS, AQUEOUS PHASE REACTIONS AND ENVIRONMENTAL EFFECTS. The oxidation process of sulfur(IV) species by oxygen, ozone and nitrogen oxides, catalysed by trace metal ions, can play an important role in atmospheric chemistry processes like acid rain, visibility degradation and health hazard. An overview of the more relevant investigations on emissions sources, aqueous phase conversion process and environmental impact is presented.
