The Dangers of Hydrogen Sulfide, AKA “Sewer Gas” A naturally occurring gas, hydrogen sulfide, or “H2S,” is toxic at high concentrations. Prolonged or acute exposure to the gas can cause eye irritation, headache, nausea fatigue, and – in extreme cases – death. Smell
Though not entirely toxic, long exposure to sewer gas can cause serious respiratory problems. Enough of it can even cause symptoms of sewer gas poisoning. The most basic way of telling if you have a sewer gas leak is its smell.

Prolonged exposure may cause nausea, tearing of the eyes, headaches or loss of sleep. Airway problems (bronchial constriction) in some asthma patients. Possible fatigue, loss of appetite, headache, irritability, poor memory, dizziness. Slight conjunctivitis ("gas eye") and respiratory tract irritation after 1 hour.
Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory and dizziness. Breathing very high levels of hydrogen sulfide can cause death within just a few breaths. There could be a loss of consciousness after one or more breaths.

Gentle but effective tongue cleaning may also be required. A variety of tongue brushes and scrapers have been produced in recent years.
No, it does not. Carbon monoxide detectors DO NOT detect sewer gas. These devices are designed to detect only the presence of carbon monoxide, and thus will not pick up on the other gases that are found in a sewer gas mixture.
