WebApr 13, 2024 · 1.Introduction. Hydrogen sulfide (H 2 S) is a noxious, colorless, and flammable gas with a rotten egg odor, originating from petroleum drilling, coal mining, and bacterial metabolism [1, 2].Combustion of H 2 S leads to the emission of harmful sulfur oxides that could cause severe environmental disasters such as acid rain and smog [3, … WebSmall amounts of H2S occur in crude petroleum and natural gas can contain up to 90% H2S. Source; In general, working in the following areas and conditions increases a worker's risk of overexposure to hydrogen sulfide: Confined spaces (for example pits, manholes, tunnels, wells) where H2S can build up to dangerous levels.
