Global sulfate production plays a key role in aerosol radiative forcing; more than half of this production occurs in clouds. We found that sulfur dioxide oxidation catalyzed by natural transition metal ions is the dominant in-cloud oxidation pathway. The pathway

A coumarin-hemicyanine dye was reported for ratiometric fluorescent detection of SO2 derivatives HSO3(-) and SO3(2-) based on a novel addition-rearrangement cascade reaction.

The regulation of the emissions of 'traditional' primary air pollutants (fluorides, sulfur dioxide) has changed the pattern of exposure of ecological systems, with greatly reduced exposure close to sources, but with a smaller effect in some remote areas. Measurements show

The atmospheric pollutant sulfur dioxide (SO(2)) is endogenously generated from the normal metabolism of sulfur-containing amino acids through the aspartate aminotransferase pathway. SO(2) is produced in cardiovascular tissues, and the aspartate aminotransferase mRNA is localized in endothelia and in vascular

Sulfur dioxide is considered a toxic gas in air pollution and detrimental to many organs, however, it can be generated endogenously in the cardiovascular system in vivo. Gaseous sulfur dioxide has an endothelium-dependent vasorelaxing effect at low concentrations, but is
