FULL STORY. Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called swamp gas, this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions.
If you indeed notice a rotten egg odor, it may be sewer gas. Sewer gas is mostly methane, which is odorless, but itâs almost always mixed with other gases, the most common of which is hydrogen sulfide (for you chemistsâH2S) which creates the rotten egg smell. The hydrogen sulfide comes from decomposing organic matter, either animal or vegetable.
