It comprises a mixture of gases, including hydrogen sulfide, ammonia, and more. The hydrogen sulfide in sewer gas is what gives it its signature rotten egg smell. Sewer gas isnt necessarily toxic at low levels. However, chronic exposure, or higher levels of exposure, can cause symptoms of sewer gas poisoning.
