For example, hydrogen sulfide occurs naturally in crude oil , natural gas, and in hot springs. Bacterial breakdown of human and animal waste also produced hydrogen sulfide. Humans release hydrogen sulfide through petroleum drilling and refining, wastewater treatment, and paper mills. The hydrogen sulfide content of natural gas is one of the main safety concerns associated with the use of natural gas. Natural gas with especially high levels of hydrogen sulfide is referred to as sour gas.

Some of this sulfur can be removed through a "sweetening" process, called the "amine process" or more commonly the "Girdler process". It is used in most gas sweetening operations and is done mainly using amine solutions that remove the hydrogen sulfide. Hydrogen sulfide is used primarily to produce sulfuric acid and sulfur. It is also used to create a variety of inorganic sulfides used to create pesticides, leather, dyes, and pharmaceuticals. Hydrogen sulfide is used to produce heavy water for nuclear power plants like CANDU reactors specifically.

Hydrogen sulfide can also be used in agriculture as a disinfectant. It is also widely used in chemical analysis. Iron smelters, landfills, food processing plants, and breweries are some examples of industrial sources that produce or use hydrogen sulfide. H 2 S precipitates many inorganic cations [e.
