What is a Hydrogen Sulfide (H2S)?

Hydrogen Sulfide (H2S) is an inorganic compound with the chemical formula H2S, composed of sulfur and hydrogen. It is a colorless gas with a distinctive foul odor, often likened to the smell of rotten eggs. It is produced naturally in environments such as volcanic activity, hot springs, and decaying organic matter, and is also associated with the extraction and refining of petroleum and natural gas. Hydrogen sulfide is highly toxic and can cause irritation of the eyes and throat even at low concentrations. At higher concentrations, it can lead to respiratory failure and potentially fatal poisoning. For this reason, hydrogen sulfide is strictly regulated and handled as a hazardous material.

Industrially, hydrogen sulfide is used in chemical synthesis and plays a significant role in the production of sulfur-containing chemicals and metal refining. It is also used in gas analysis and environmental monitoring. Due to its characteristic rotten egg odor, hydrogen sulfide is commonly employed in detecting gas leaks.
