Anthropogenic sources of sulfur dioxide may be as high as 70% of total global emissions; half of this is a result of fossil fuel combustion. As a pollutant, SO2emissions are closely monitored, as this compound can be oxidized to sulfuric acid, leading to acid rain. The presence of SO2in ...
Sulfur dioxide is a compound formed by the combination of the elements sulfur and oxygen. On a weight basis, the proportion of the elements is about I part sulfur to I part oxygen, or more exactly, 50.05 percent to 49.95 percent, respectively. At standard conditions of temperature and pressur...
