4/12/2023 0 Comments Hydrogen sulfideSome people have greater sensitivities than others to the potential effects. Some people are able to detect it at very low concentrations while others may not smell it. Hydrogen sulfide is both an irritant and a chemical asphyxiant (it will take the place of oxygen so there is not enough for someone to breathe). How can hydrogen sulfide affect my health? Some foods contain high sulfur levels, particularly plants in the onion family, especially garlic. A small amount of hydrogen sulfide is produced by bacteria in your mouth and gastrointestinal tract.Although rare in Washington, municipal drinking water or well water can contain hydrogen sulfide. Hydrogen sulfide is slightly soluble (it can dissolve) in water and can be found in geothermal springs and some swamps.Shorelines with significant amounts of decaying organic material, such as seaweed, have caused hydrogen sulfide problems on beaches. Mudflats, with oxygen-starved organic material in the sediment, can produce generally low levels of hydrogen sulfide.Workers involved in petroleum and natural gas drilling and refining, wastewater treatment, rayon textiles, tanneries, landfills, and farms with manure storage pits my be exposed to higher levels of hydrogen sulfide.People living near a wastewater treatment plant, gas and oil drilling operation, farm with manure storage or livestock confinement facilities, or a landfill may be exposed to higher levels of hydrogen sulfide.Breathing contaminated air that contains hydrogen sulfide.How can I be exposed to hydrogen sulfide? Hydrogen sulfide's chemical formula is H 2S. Hydrogen sulfide is used in preparation of other sulfur chemical compounds and can be a byproduct of industrial activities such as pulp and paper mills, manufacturing rayon, food processing, tanneries and fur processing, and oil and natural gas refineries. Hydrogen sulfide also occurs naturally in the human body and is produced by human and animal wastes. Beaches with large amounts of decaying seaweed and mudflats with trapped organic material below the sediment can produce hydrogen sulfide. It occurs in unrefined natural gas and petroleum, volcanic gases, sulfur deposits, hot springs, and swamps. In the environment, hydrogen sulfide is produced from the bacterial breakdown or decomposition of dead plant and animal matter, especially when there is a lack of oxygen. Hydrogen sulfide is heavier than air, so it can build up in low-lying areas and enclosed spaces. This condition, known as olfactory fatigue, can also occur when people have been exposed to hydrogen sulfide for a longer period of time. At extremely high levels, a person can lose their ability to smell the gas and become unaware of its presence. At high concentration levels, it has a sickening sweet odor. It is commonly known as sewer gas, stink damp, and manure gas. Some biological applications of these donors were also discussed.Hydrogen sulfide is a colorless, flammable gas that smells like rotten eggs at low concentration levels in the air. In this review we summarized the developments and limitations of currently available donors including H 2S gas, sulfide salts, garlic-derived sulfur compounds, Lawesson's reagent/analogs, 1,2-dithiole-3-thiones, thiol-activated donors, photo-caged donors, and thioamino acids. It is therefore important to study the chemistry and pharmacology of exogenous H 2S and to be aware of the limitations associated with the choice of donors used to generate H 2S in vitro and in vivo. These compounds are not only useful research tools, but also potential therapeutic agents. Hydrogen sulfide releasing agents (also known as H 2S donors) have been widely used in these fields. The fields of H 2S physiology and pharmacology have been rapidly growing in recent years, but a number of fundamental issues must be addressed to advance our understanding of the biology and clinical potential of H 2S in the future. Hydrogen sulfide (H 2S) is a newly recognized signaling molecule with very potent cytoprotective actions.
