Occurring naturally in crude petroleum, natural gas, volcanic gases and hot springs, hydrogen sulphide can also result from bacterial breakdown of organic matter. Bacteria found in your mouth and digestive tract also produce hydrogen sulphide during the digestion of food containing vegetable or animal proteins.
Hydrogen sulphide is a highly toxic gas, reacting with the enzymes in the bloodstream to inhibit cell respiration. While at low concentrations this can cause symptoms such as skin irritation and headaches, high concentrations may lead to unconsciousness, respiratory distress, or long-term neurological effects- making detection of its presence of the utmost importance.
