Hydrogen sulfide
Hydrogen Sulfide
Hydrogen sulfide (pronounced: /ˈhaɪdrədʒən ˈsʌlfaɪd/) is a chemical compound with the formula H2S. It is a colorless, toxic, and flammable gas that is responsible for the foul smell of rotten eggs and is produced naturally in the human body.
Etymology
The term "hydrogen sulfide" is derived from the chemical elements that make up the compound: hydrogen and sulfur. The suffix "-ide" is used in chemistry to denote that the compound is a binary compound of the element.
Production
Hydrogen sulfide is produced naturally in the human body and is also a by-product of certain industrial processes such as petroleum refining, natural gas processing, and sewage treatment. It can also be produced by certain types of bacteria in the absence of oxygen, a process known as anaerobic respiration.
Health Effects
Exposure to high concentrations of hydrogen sulfide can be harmful and can lead to a range of health effects, from eye irritation and nausea to unconsciousness and even death in extreme cases. Chronic exposure to lower levels of the gas can also cause health problems such as fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness.
