Description
Hydrogen Sulfide is a colorless, very poisonous, flammable gas with the characteristic foul odor of rotten eggs. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers where anaerobic digestion can take place. It also occurs in volcanic gases, “natural gas”, and some well waters. Hydrogen sulfide has numerous names, some of which are archaic.Small amounts of hydrogen sulfide occur in crude oil, but natural gas can contain up to 90%. About 10% of the total global emission of H2S is due to human activity.
