Sulfur is found in meteorites. R.W. Wood suggests that the dark area near the crater Aristarchus is a sulfur deposit. Sulfur occurs native in the vicinity of volcanos and hot springs. It is widely distributed in nature as iron pyrites, galena, sphalerite, cinnabar, stibnite, gypsum, epsom salts, celestite, barite, etc.
The gas is also a lung irritant. The EPA regulates sulfur dioxide emissions along with five other so-called criteria pollutants, including lead and carbon monoxide. Who knew?
