	Chemistry : Periodic Table : sulphur : key information
		Sulphur is found in meteorites, volcanoes, hot springs, and as galena, gypsum, Epsom salts, and barite.
		Sulphur dioxide is a dangerous component in atmospheric air pollution and is one of the factors responsible for acid rain.
		In the Frasch process underground deposits of sulphur are forced to the surface using superheated water and steam (160°C, 16 atmospheres, to melt the sulphur) and compressed air (25 atmospheres).

	Where does Sulphur Come From?
		Sulphur is considered to be one of the most common elements in the earth's crust, mostly in the form of sulfide or sulfate compounds.
		Sulphur is burned to form sulphuric acid, which is then used to convert phosphate rock to phosphoric acid, the foundation material for phosphatic fertilizer.
		Sulphuric acid is also used in the manufacture of detergents and animal feed and one of its largest uses is for ore and metal processing.

		The second is to identify areas of difficulty in the study of the sulphur cycle which may arise, usually at the interface between different reservoirs in the cycle, and thus, at the interface between the different disciplines involved.
		The approximate 1980 regional apportionment of fossil-fuel sulphur emissions is: China and Japan, 16%; USA and Canada, 28%; Europe, 34%; the remainder of the Northern Hemisphere, 15% ; and the Southern Hemisphere, 7% (Hameed and Dignon, 1988).

		Sulphur in fuel contributes directly to the emission of sulphur dioxide into the environment and while the majority of sulphur dioxide emissions are produced by industry and domestic heating, a significant amount is also emitted by motor vehicles.
		Sulphur dioxide, in turn, leads to the formation of sulphate particles which can be associated with a variety of health effects, and contribute to the visible haze familiar to anyone who has walked or cycled alongside traffic congested roads.
		The sulphur present in fuel reduces the efficiency of your car’s catalytic converter which means that over time it loses its ability to reduce the harmful emissions from your engine.

	A History of the Louisiana Sulphur Industry (Site not responding. Last check: )
		Although sulphur is found in many parts of the world, the American sulphur industry was born in Louisiana in the last decade of the 19th century.
		At this time all sulphur was sold in solid form, and large power shovels broke up this solid sulphur in the vats and loaded it by conveyor belts to railroad cars, ocean-going vessels and barges.
		As the sulphur industry continues to expand and grow in Louisiana, and along its coast, it maintains its course in furthering the economic well-being of the state of Louisiana.
