Hydrogen Sulfide (H2S)
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten
egg” smell. Some common names for the gas include sewer gas, stink damp,
swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas,
and hot springs. In addition, hydrogen sulfide is produced by bacterial breakdown
of organic materials and human and animal wastes (e.g., sewage).
Industrial activities that can produce the gas include petroleum/natural gas
drilling and refining, wastewater treatment, coke ovens, tanneries, and kraft
paper mills. Hydrogen sulfide can also exist as a liquid compressed gas.
