sewer gas
Pipe system fumes
Sewer gas is the mixture of toxic and nontoxic gases produced by decomposing organic matter in sewage systems.
It typically contains hydrogen sulfide, ammonia, and methane, creating the characteristic rotten-egg smell associated with sewers.
Exposure can cause illness or, in high concentrations, death: The plumber detected sewer gas leaking from a cracked pipe.
