The essential steps of the sulfur cycle are:
These are often termed as follows: Assimilative sulfate reduction Desulfuration Oxidation of hydrogen sulfide :Further ''oxidation of elemental sulfur'' by sulfur oxidizers produces sulfate. Dissimilative sulfur reduction Dissimilative sulfate reduction Human impact on the sulfur cycle is primarily in the production of Sulfur Dioxide (SO2) from industry (e.g. burning Coal ) and the Internal Combustion Engine . Sulfur dioxide can precipitate onto surfaces where it can be oxidized to sulfate in the Soil (it is also toxic to some plants), reduced to sulfide in the Atmosphere , or oxidized to sulfate in the atmosphere as Sulfuric Acid , a principal component of Acid Rain .
