3.1 Production of sulfur, thioorganic compounds, and alkali metal sulfides.It also occurs in volcanic gases, natural gas deposits, and sometimes in well-drawn water. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers this process is commonly known as anaerobic digestion, which is done by sulfate-reducing microorganisms. Despite this, the human body produces small amounts of this sulfide and its mineral salts, and uses it as a signalling molecule.
When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is stinkdamp. It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs.
