Sulfur is a yellow crystalline solid or powder. Often transported in the molten state.

Widely used in manufacture of sulfuric acid; carbon bisulfide; drugs, fungicides, gunpowder, wood pulp; rubber, and other products.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Salvage for reprocessing or dump to landfill.

Organic sulfur compounds occur in garlic, mustard, onions, and cabbage and are responsible for the odor of skunks. Sulfur occurs in living tissue and is part of some amino acids. Unlike many other inorganic elements, sulfur itself is relatively nontoxic. Sulfur and some of its salts have been used medicinally. Organosulfur compounds, such as diallyl disulfide, exhibit antiproliferative effects on cancer cells. The consumption of sulfur is a measure of national industrial development and economic activity. Sulfur is most often used as a chemical reagent, rather than as part of a finished product. In the United States,about 90% of sulfur consumed was in the form of sulfuric acid. Agricultural chemicals (primarily fertilizers) comprised about 62% of sulfur demand; petroleum refining, 26%; and metal mining, 5%.

ChEBI: Sulfur atom is a nonmetal atom and a chalcogen. It has a role as a macronutrient.

Sulfur (S) occurs naturally as a yellow, water-insoluble solid. The name is from the Latin “sulphur.” Early Greek physicians mention sulfur and the fumes from burning sulfur in religious ceremonies.Sulfur can be extracted from crude oil in the refining process, as well as from stack gases resulting from coal combustion. Sulfur occurs in fossil fuels and in metal (Fe, Pb) ores. The world resources of elemental sulfur in evaporate and volcanic deposits and sulfur associated with natural gas, petroleum, tar sands, and metal sulfides equal about 5 billion ton. The sulfur in gypsum and anhydrite is almost limitless; about 600 billion ton of sulfur is present in coal, oil shale, and shale rich in organic matter. However, recovery of sulfur from these sources poses an economic challenge due to lack of low-cost technologies. The U.S. sulfur resource is estimated at about one-fifth of the world total. Exposure may occur in numerous operations related to the mining and recovery of sulfur.

Sulfur is present in every cell in the body, primarily in proteins containing the amino acids methionine, cystine, and cysteine. Inorganic sulfates and sulfides occur in small amounts relative to total body sulfur, but the compounds that contain them are important to metabolism. Sulfur intake is thought to be adequate if protein intake is adequate and sulfur deficiency has not been reported.
Although sulfur is in the same group of the Periodic Table, Group 16(VIA), as oxygen, sulfur functions much more like phosphorus, Group 15(VA), in biological systems. In fat metabolism, sulfur plays a key role analogous to that of phosphorus in carbohydrate metabolism. Fatty acid synthesis and degradation begin and end with the same compound, acetyl-S coenzyme A (acetyl–SCoA).
