Hydrogen sulfide is the chemical compound with the formula H2S. It is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive.
Hydrogen sulfide often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers; this process is commonly known as anaerobic digestion. H2S also occurs in volcanic gases, natural gas, and some well waters. The human body produces small amounts of H2S and uses it as a signaling molecule.
Dissolved in water, hydrogen sulfide is known as hydro-sulfuric acid or sulfhydric acid, a weak acid.
Swedish chemist Carl Wilhelm Scheele is credited with having discovered hydrogen sulfide in 1777.
The British English spelling of this compound is hydrogen sulfide, but this spelling is not recommended by the International Union of Pure and Applied Chemistry nor the Royal Society of Chemistry.
Quite often a lot of people asking me such a silly quitestions that I have a moral duty to publish safety videos. Remember! Working with chemicals is a dangerous thing if you do not know what you are doing. Plaese watch this quick video about dangers of Hydrogen Sylfide. How to Identify it and how to treat a casualty.

Hydrogen sulfide is a colorless, flammable, and potentially extremely hazardous gas that has a "rotten egg" smell. It occurs naturally in crude petroleum, natural gas and hot springs. It is also produced by the microbial breakdown of organic materials, including human and animal wastes.
Examples of industrial activities that can produce hydrogen sulfide include petroleum and natural gas drilling, refining, wastewater treatment, coke ovens, tanneries and some types of paper mill processing.
Hydrogen sulfide is heavier than air and may travel along the ground. It can collect in low-lying and enclosed, poorly-ventilated areas such as basements, manholes, sewer lines, underground telephone vaults and manure pits. For work within confined spaces or where the gas may collect, people need to use appropriate procedures for identifying hazards, monitoring and entering confined spaces.
The primary route of hydrogen sulfide exposure is through inhalation. People can smell the "rotten egg" odor of hydrogen sulfide at low concentrations in air. However, with continuous low-level exposure, or at high concentrations, a person loses their ability to smell the gas even though it is still present due to olfactory fatigue.
Hydrogen sulfide is highly flammable and can be explosive. If ignited, the gas burns to produce toxic vapors and gases, such as sulfur dioxide.
It is both an irritant and a chemical asphyxiant with effects on both oxygen utilization and the central nervous system. Its health effects can vary depending on the level and duration of exposure. Repeated exposure can result in health effects occurring at levels that were previously tolerated without any effect.
These are just a few things to know about hydrogen sulfide and exposure risks. To learn more about this or other indoor air quality, health & safety, and environmental issues, please visit the websites shown in the video.

DESCRIPTION: Sulfur dioxide preservatives in dried fruit, sulfites in wine, and the putrefaction of undigested animal protein in the colon can release hydrogen sulfide, the rotten egg gas associated with inflammatory bowel disease.
More than 35 years ago studies started (http://www.ncbi.nlm.nih.gov/pubmed/412611) implicating sulfur dioxide preservatives in the exacerbation of asthma. This so-called “sulfite-sensitivity” seems to affect only about (http://www.ncbi.nlm.nih.gov/pubmed/8586770) 1 in 2000 people, so I recommended those with asthma avoid it, but otherwise I considered the preservative harmless. I am now not so sure, and advise people to avoid it when possible. How could companies just add things to foods without adequate safety testing? See Who Determines if Food Additives are Safe? (http://nutritionfacts.org/video/who-determines-if-food-additives-are-safe/) For other additives that may be a problem, see Titanium Dioxide & Inflammatory Bowel Disease (http://nutritionfacts.org/video/titanium-dioxide-inflammatory-bowel-disease/) and Is Carrageenan Safe?

Hydrogen Sulfide (H2S):
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage). It is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements, manholes, sewer lines and underground telephone/electrical vaults.
Detection by Smell:
Can be smelled at low levels, but with continuous low level exposure or at higher concentrations you lose your ability to smell the gas even though it is still present.
At high concentrations – your ability to smell the gas can be lost instantly.
DO NOT depend on your sense of smell for indicating the continuing presence of this gas or for warning of hazardous concentrations.
Health Effects:
Health effects vary with how long, and at what level, you are exposed. Asthmatics may be at greater risk.
Low concentrations – irritation of eyes, nose, throat, or respiratory system; effects can be delayed.
Moderate concentrations – more severe eye and respiratory effects, headache, dizziness, nausea, coughing, vomiting and difficulty breathing.
High concentrations – shock, convulsions, unable to breathe, coma, death; effects can be extremely rapid (within a few breaths).
Before Entering Areas with Possible Hydrogen Sulfide
The air needs to be tested for the presence and concentration of hydrogen sulfide by a qualified person using test equipment. This individual also determines if fire/explosion precautions are necessary.
If gas is present, the space should be ventilated.
If the gas cannot be removed, use appropriate respiratory protection and any other necessary personal protective equipment (PPE), rescue and communication equipment. Atmospheres containing high concentrations (greater than 100 ppm) are considered immediately dangerous to life and health (IDLH) and a self-contained breathing apparatus (SCBA) is required.

In this video, I generate hydrogen sulfide using hydrochloric acid (HCl) and iron sulfide (FeS).
I bubble the gas through a saturated solution of copper sulfate to limit the amount of H2S released into the environment and to demonstrate it's (old) use as an analytical chemistry technique.

Hydrogen sulfide is a colorless, flammable, and potentially extremely hazardous gas that has a "rotten egg" smell. It occurs naturally in crude petroleum, natural gas and hot springs. It is also produced by the microbial breakdown of organic materials, including human and animal wastes.
Examples of industrial activities that can produce hydrogen sulfide include petroleum and natural gas drilling, refining, wastewater treatment, coke ovens, tanneries and some types of paper mill processing.
Hydrogen sulfide is heavier than air and may travel along the ground. It can collect in low-lying and enclosed, poorly-ventilated areas such as basements, manholes, sewer lines, underground telephone vaults and manure pits. For work within confined spaces or where the gas may collect, people need to use appropriate procedures for identifying hazards, monitoring and entering confined spaces.
The primary route of hydrogen sulfide exposure is through inhalation. People can smell the "rotten egg" odor of hydrogen sulfide at low concentrations in air. However, with continuous low-level exposure, or at high concentrations, a person loses their ability to smell the gas even though it is still present due to olfactory fatigue.
Hydrogen sulfide is highly flammable and can be explosive. If ignited, the gas burns to produce toxic vapors and gases, such as sulfur dioxide.
It is both an irritant and a chemical asphyxiant with effects on both oxygen utilization and the central nervous system. Its health effects can vary depending on the level and duration of exposure. Repeated exposure can result in health effects occurring at levels that were previously tolerated without any effect.
These are just a few things to know about hydrogen sulfide and exposure risks. To learn more about this or other indoor air quality, health & safety, and environmental issues, please visit the websites shown in the video.

DESCRIPTION: Sulfur dioxide preservatives in dried fruit, sulfites in wine, and the putrefaction of undigested animal protein in the colon can release hydrogen sulfide, the rotten egg gas associated with inflammatory bowel disease.
More than 35 years ago studies started (http://www.ncbi.nlm.nih.gov/pubmed/412611) implicating sulfur dioxide preservatives in the exacerbation of asthma. This so-called “sulfite-sensitivity” seems to affect only about (http://www.ncbi.nlm.nih.gov/pubmed/8586770) 1 in 2000 people, so I recommended those with asthma avoid it, but otherwise I considered the preservative harmless. I am now not so sure, and advise people to avoid it when possible. How could companies just add things to foods without adequate safety testing? See Who Determines if Food Additives are Safe? (http://nutritionfacts.org/video/who-determines-if-food-additives-are-safe/) For other additives that may be a problem, see Titanium Dioxide & Inflammatory Bowel Disease (http://nutritionfacts.org/video/titanium-dioxide-inflammatory-bowel-disease/) and Is Carrageenan Safe? (http://nutritionfacts.org/video/is-carrageenan-safe/)
For more on the relationship between hydrogen sulfide and inflammatory bowel disease, see my video Preventing Ulcerative Colitis with Diet (http://nutritionfacts.org/video/preventing-ulcerative-colitis-with-diet/). More on this epid fermentation battle in our gut in Stool pH and Colon Cancer (http://nutritionfacts.org/video/stool-ph-and-colon-cancer/).
Does the sulfur-containing amino acid methionine sound familiar? You may remember it from such hits as Starving Cancer with Methionine Restriction (http://nutritionfacts.org/video/starving-cancer-with-methionine-restriction/) and Methionine Restriction as a Life Extension Strategy (http://nutritionfacts.org/video/methionine-restriction-as-a-life-extension-strategy/).
These short chain fatty acids released by our good bacteria when we eat fiber and resistant starches is what may be behind the second meal effect: Beans and the Second Meal Effect (http://nutritionfacts.org/video/beans-and-the-second-meal-effect/).

Hydrogen Sulfide (H2S):
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage). It is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements, manholes, sewer lines and underground telephone/electrical vaults.
Detection by Smell:
Can be smelled at low levels, but with continuous low level exposure or at higher concentrations you lose your ability to smell the gas even though it is still present.
At high concentrations – your ability to smell the gas can be lost instantly.
DO NOT depend on your sense of smell for indicating the continuing presence of this gas or for warning of hazardous concentrations.
Health Effects:
Health effects vary with how long, and at what level, you are exposed. Asthmatics may be at greater risk.
Low concentrations – irritation of eyes, nose, throat, or respiratory system; effects can be delayed.
Moderate concentrations – more severe eye and respiratory effects, headache, dizziness, nausea, coughing, vomiting and difficulty breathing.
High concentrations – shock, convulsions, unable to breathe, coma, death; effects can be extremely rapid (within a few breaths).
Before Entering Areas with Possible Hydrogen Sulfide
The air needs to be tested for the presence and concentration of hydrogen sulfide by a qualified person using test equipment. This individual also determines if fire/explosion precautions are necessary.
If gas is present, the space should be ventilated.
If the gas cannot be removed, use appropriate respiratory protection and any other necessary personal protective equipment (PPE), rescue and communication equipment. Atmospheres containing high concentrations (greater than 100 ppm) are considered immediately dangerous to life and health (IDLH) and a self-contained breathing apparatus (SCBA) is required.

Hydrogen sulfide (or hydrogen sulphide) is the chemical compound with the formula H2S. It is a colorless, very poisonous, flammable gas with the characteristic foul odor of rotten eggs. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers (anaerobic digestion). It also occurs in volcanic gases, natural gas, and some well waters. The human body produces small amounts of H2S and uses it as a signaling molecule.
