Gaseous sulfur pollutants from urban and natural sources
Major aspects of the circulation through the atmospheric environment of sulfur pollutants have been estimated, including source magnitudes, residual atmospheric concentrations, and scavenging processes. The compounds considered include SO/sub 2/ and H/sub 2/S, as well as sulfates. One-third of the sulfur reaching the atmosphere comes from pollutant sources, mainly as SO/sub 2/. Within the atmosphere there is a net transfer of sulfur from land to ocean areas. Pollutant sources annually amount to 73 x 10+6 tons as sulfur while natural sources amount to 142 x 10+6 tons, mainly as H/sub 2/S and sulfate sea spray. More than two thirds of the natural and pollutant sulfur emissions occur in the northern hemisphere. When only pollutant emissions are considered, 93 percent occur in the northern hemisphere.
