About Hydrogen Sulfide H2S

Hydrogen Sulfide (H2S) is a colorless gas, with a strong odor of rotten eggs. According to the U.S. Environmental Protection Agency’s (EPA) Toxicological Review, H2S gas is absorbed rapidly through the lungs and is distributed to the blood, brain, lung, heart, liver, spleen and kidneys. It is classed as a chemical asphyxiant, similar to carbon monoxide and cyanide gases; an asphyxiant is an agent or event which induces asphyxia, also known as suffocation. Asphyxiant gases are a major issue because many of them are largely inert. You can detect low levels of Hydrogen Sulfide because of its distinct smell, but high levels may not be detected by odor since this gas can paralyze olfactory nerves.

Health Effects of Hydrogen Sulfide H2S

The effects of H2S can be acute and/or chronic. According to OSHA, the U.S. Occupational Safety & Health Administration, inhalation of high concentrations of Hydrogen Sulfide can be fatal. Some data suggests that children may be more susceptible to neurological effects, than adults. To the rigdh is a chart showing the effects of Hydrogen Sulfide (H2S) at different levels.
