These sulfides are produced when things decay without air. Sulfur compounds are chemical compounds containing sulfur ions. Sulfur comes in several forms: oxidation states of -2 (hydrogen sulfide), +4 (sulfur dioxide, sulfites) and +6 (sulfuric acid, sulfates) are most common, although there are other oxidation states.
First, sulfur is an element of the earth. This element is essential to life, and is the eighth most prevalent element in the human body. No one is allergic to sulfur itself. Sulfur is not present as an isolated element in the body, but in combination with other elements and, most often, in complex molecules. The primary placement of sulfur in the human body is in the sulfur-containing amino acids: methionine, cysteine, homocysteine (and related cystine, homocystine), and taurine.
