What is hydrogen sulfide used for?
Overview. Hydrogen sulfide (H₂S) is a colorless gas with a strong odor of rotten eggs. Exposure to hydrogen sulfide may cause irritation to the eyes and respiratory system. It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite.

Hydrogen sulfide is one of the leading causes of workplace gas inhalation deaths in the United States. According to the Bureau of Labor Statistics (BLS), hydrogen sulfide caused 46 worker deaths between 2011 and 2017. Why is hydrogen sulfide so deadly? It is highly flammable and toxic, even at low concentrations.
Hydrogen Sulfide – Overviewhttps://www.osha.gov › hydrogen-sulfidehttps://www.osha.gov › hydrogen-sulfide
At low levels, hydrogen sulfide causes irritation of the eyes, nose, and throat. Moderate levels can cause headache, dizziness, nausea, and vomiting, as well as coughing and difficulty in breathing. Higher levels can cause shock, convulsions, coma, and death.

Moderate concentrations can cause more severe eye and respiratory irritation (including coughing, difficulty breathing, accumulation of fluid in the lungs), headache, dizziness, nausea, vomiting, staggering and excitability. Hydrogen sulfide is heavier than air and may travel along the ground.

What is the chemical name for rotten egg gas?
Hydrogen sulfide
Hydrogen sulfide is a colorless, flammable gas that smells like rotten eggs at low concentration levels in the air. It is commonly known as sewer gas, stink damp, and manure gas.
What causes hydrogen sulfide?
Most hydrogen sulfide in the air comes from natural sources. It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such as bogs and swamps. Volcanoes, hot springs and underwater thermal vents also release hydrogen sulfide.
What is Henry’S law constant of H2S?
K and T = 303. K from missing citation was used to derive kH and -Δ kH/R. Above T = 303.
Henry’s Law constant (water solution)

Is hydrogen sulfide toxic to humans?
The health effects of hydrogen sulfide depend on how much H2S a worker breathes and for how long. However, many effects are seen even at low concentrations. Effects range from mild, headaches or eye irritation, to very serious, unconsciousness and death.
Is hydrogen sulfide harmful to humans?
Exposure to hydrogen sulfide may cause irritation to the eyes and respiratory system. It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite. Workers may be harmed from exposure to hydrogen sulfide.
Which poison smells like rotten eggs?
hydrogen sulfide
How can hydrogen sulfide affect health? Hydrogen sulfide has a characteristic rotten egg smell which can be detected at very low levels, well below those that are known to cause health effects.
Why does my body smell like sulfur?
Hypermethioninemia is an inherited condition. It occurs when there’s excess amino acid methionine in your blood. A sulfur-like odor often occurs when the methionine isn’t broken down properly within the body. You may also experience breath or sweat that smells like sulfur.
What is the unit of Henry’s constant?
What is the unit for Henry’s law constant? Henry’s law constant is expressed in mol L–1 bar–1.
What is the Henry’s law constant for CO2?

How long does hydrogen sulfide stay in the air?
approximately 1–42 days
Hydrogen sulfide remains in the atmosphere for approximately 1–42 days, depending on the season. It can change into sulfur dioxide and sulfates in the air.
How does the body get rid of hydrogen sulfide?
People are normally exposed to hydrogen sulfide in air by breathing it in or by skin/eye contact. Any absorbed hydrogen sulfide does not accumulate in the body as it is rapidly metabolised in the liver and excreted in the urine. Hydrogen sulfide usually breaks down in air in about 3 days and is dispersed by wind.
What are three symptoms you would experience if you are exposed to hydrogen sulfide?
Symptoms/Effects
Prolonged exposure may cause nausea, tearing of the eyes, headaches or loss of sleep. Airway problems (bronchial constriction) in some asthma patients. Possible fatigue, loss of appetite, headache, irritability, poor memory, dizziness.
How long can you be exposed to hydrogen sulfide?
OSHA: The legal airborne permissible exposure limit (PEL) is 20 ppm not to be exceeded at any time, and 50 ppm as a maximum peak, not to be exceeded during any 10-minute work period. NIOSH: The recommended airborne exposure limit (REL) is 10 ppm, which should not be exceeded during any 10-minute work period.
Why do you smell like pee?
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotting fish, rotting eggs, garbage, or urine.
What poison smells like onions?
Acrylonitrile
Acrylonitrile is a clear, colorless or slightly yellow liquid that is highly volatile and toxic. Acrylonitrile vapor is heavier than air. It has a pungent odor of onion or garlic that does not provide adequate warning of hazardous levels. Acrylonitrile is poisonous by inhalation, ingestion or skin contact.
Why do I smell pee in my nose?
Nasal congestion or sinusitis
Both nasal congestion and sinusitis can result from bacterial infections, allergies, or irritation of the nasal cavities. They often result in bad breath, which in some people could smell similar to urine.
Can liver problems cause body odor?
Certain health conditions.
Some metabolic diseases can cause a distinctive body odor, particularly in their later stages. These include diabetes, as well as advanced kidney and liver disease.
What is Henry’s law write its formula?
Henry’s law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas. And mole fraction (X) of the gas in a solution is proportional to the partial pressure (P) of the gas. P=KHX. Solve any question of Solutions with:- Patterns of problems.
What is Henry’s law used for?
Henry’s law states that when a gaseous mixture (e.g., the atmosphere) is in contact with a solution, the amount of any gas in that mixture that dissolves in the solution is in direct proportion to the partial pressure of that gas.
What is the unit of Henry’s law?
How do you calculate Henry’s constant?
Henry’s law shows that the concentration of a solute gas in a solution is directly proportional to the partial pressure of the gas over the solution. P = KHC where:P is the partial pressure of the gas above the solution.KH is the Henry’s law constant for the solution.
How can I reduce the hydrogen sulfide in my gut?
Limiting the bacterial fermentation of sulphur containing amino acids by increasing fibre intake and preventing excessive protein intake can help prevent excessive hydrogen sulphide production.
What foods produce hydrogen sulfide?
Beef, eggs, pork, fish, and poultry are rich in sulfur, which can be turned into hydrogen sulfide by gut bacteria, resulting in foul-smelling gas that is reminiscent of rotten eggs. Protein supplements may also contain ingredients that cause flatulence and encourage excessive wind.
What are 3 symptoms you would experience if you are exposed to hydrogen sulfide?
Possible fatigue, loss of appetite, headache, irritability, poor memory, dizziness. Slight conjunctivitis (“gas eye”) and respiratory tract irritation after 1 hour. May cause digestive upset and loss of appetite. Coughing, eye irritation, loss of smell after 2-15 minutes (olfactory fatigue).
