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.
Hydrogen sulfide gas is a naturally occuring chemical. The gas has a characteristic rotten egg odor at low concentrations. About half of the population can smell it at concentrations as low as 8 parts per billion (ppb) in air, and more than 90% can smell it at levels of 50 ppb.
