Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is toxic, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11]
Hydrogen sulfide (H2S) is a noxious gas characterized by its distinctive stench reminiscent of rotten eggs. [1] It goes by several colloquial names, including sewer gas, stink damp, swamp gas, and manure gas. [2] This gas naturally occurs in crude petroleum, natural gas, hot springs, and certain food items.
Biogenic sulfide corrosion is a bacterially mediated process of forming hydrogen sulfide gas and the subsequent conversion to sulfuric acid that attacks concrete and steel within wastewater environments. The hydrogen sulfide gas is biochemically oxidized in the presence of moisture to form sulfuric acid.
Hydrogen sulfide: Hydrogen sulfide poisoning: Hydrogen sulfide is associated with sour natural gas, crude oil, anoxic water conditions and sewers (more information needed). hydrogen sulfide is present in some lakes and caves and can also be absorbed through the skin.

Hydrogen sulfide is also a potent cellular toxin, blocking the cytochrome system and inhibiting cellular respiration. More water-soluble gases (e.g. chlorine, ammonia, sulfur dioxide, hydrogen chloride) dissolve in the upper airway and immediately cause mucous membrane irritation, which may alert people to the need to escape the exposure.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The industrial hydrodesulfurization processes include facilities for the capture and removal of the resulting hydrogen sulfide (H 2 S) gas. In petroleum refineries, the hydrogen sulfide gas is then subsequently converted into byproduct, sulfur (S) or sulfuric acid (H 2 SO 4). In fact, the vast majority of the 64,000,000 metric tons of sulfur ...
Hydrogen sulfide is a toxic gas, it can cause breathing problems, asphyxiation and death. It also is very corrosive to metals [ 3 ] which restricts the materials that can be used for piping and other equipment for handling sour gas, as many metals are sensitive to sulfide stress cracking .
