What is Hydrogen Sulfide?
CAS#: 007783-06-4
Hydrogen sulfide (H2S) occurs naturally in crude petroleum,
natural gas, volcanic gases, and hot springs. It can also result
from bacterial breakdown of organic matter. It is also produced
by human and animal wastes. Bacteria found in your mouth and
gastrointestinal tract produce hydrogen sulfide from bacteria
decomposing materials that contain vegetable or animal proteins.
Hydrogen sulfide can also result from industrial activities,
such as food processing, coke ovens, kraft paper mills, tanneries,
and petroleum refineries.
Hydrogen sulfide is a flammable, colorless gas with a characteristic
odor of rotten eggs. It is commonly known as hydrosulfuric acid,
sewer gas, and stink damp. People can smell it at low levels.
