It is insidious in that it quickly deadens the sense of smell. Sulfur dioxide is a dangerous component in atmospheric air pollution. In 1975, University of Pennsylvania scientists reported synthesis of polymeric sulfur nitride, which has the properties of a metal, although it contains no metal atoms. The material has unusual optical and electrical properties. As soil conditioner.
Sulfur is used in the production of sulfuric acid, carbon disulfide and hydrogen sulfide.
It is also used in the wood pulping industry for the vulcanization of rubber, in soil nutrients and asphalt extension. According to a recent US Patent, daily ingestion of 2 g sulfur is said to be effective as insect repellant in heavily infested tropical areas. Two-thirds of the world sulfur production is consumed in the mfr of fertilizer. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin. At room temp the thermodynamic stable sulfur modification is orthorhombic sulfur that converts at 94 deg C to monoclinic sulfur.
