The Sulfur Cycle

1980
The geochemistry of sulfur is to a great extent affected by the biosphere. Living organisms transform sulfur from one oxidation state to another, thus changing the chemical properties of sulfur compounds and their distribution in the atmosphere, soils, waters and sediments.

The sulfur cycle.

Science (New York, N.Y.), 1972
Even granting our uncertainties about parts of our model of the sulfur cycle, we can draw some conclusions from it: 1) Man is now contributing about one half as much as nature to the total atmospheric burden of sulfur compounds, but by A.D. 2000 he will be contributing about as much, and in the Northern Hemisphere alone he will be more than matching ...

Sulfuric Acid on Europa and the Radiolytic Sulfur Cycle

Science, 1999
A comparison of laboratory spectra with Galileo data indicates that hydrated sulfuric acid is present and is a major component of Europa's surface. In addition, this moon's visually dark surface material, which spatially correlates with the sulfuric acid concentration, is identified as radiolytically altered sulfur polymers.

The Sulfur Cycle

2005
Publisher Summary The chapter discusses the biologically mediated sulfur metabolisms, which involve the reduction of sulfur compounds, the oxidative processes, and the disproportionation of sulfur compounds. Sulfur is an essential nutrient element and constitutes around 0.5 to 1.0% of the dry weight of prokaryotic organisms.
