Emission control from stationary power sources (carbon disulfide from biogenic sources)

Biogenic sources are thought to constitute a large fraction of the atmospheric sulfur burden. Direct measurements of carbon disulfide emission rates were made in a salt marsh on the coast of North Carolina in summer 1977. An emission flux reactor technique was employed to determine emission rates. In the aerated chamber, the emission rates over and in the vicinity of marsh grass ranged from less than 0.05 to 0.3 g sulfur/sq m/yr. Such emission rates do not contribute substantially to either the natural sulfur cycle or the stratospheric sulfate aerosol layers. (1 graph, 1 map, 19 references, 3 tables)
