| Material Notes | a flammable, poisonous gas with a characteristic odor of rotten eggs. it is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. (from merck index, 11th ed) Found in coal pits, gas wells, sulfur springs, produced from decaying sulfur-containing org. matter. Synth. from CaS + MgCl2 + H2O; Highly toxic (CCD) Hydrogen sulfide (British English: hydrogen sulphide) is the chemical compound with the formula H2S. It is a colorless, very poisonous, flammable gas with the characteristic foul odor of rotten eggs at concentrations up to 100 parts per million. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers; this process is commonly known as anaerobic digestion. It also occurs in volcanic gases, natural gas, and some well waters. The human body produces small amounts of H2S and uses it as a signaling molecule. (Wikipedia) |
