Side Effects of Inhaling Hydrogen Sulphide Gas – The Harmful Substances

The hydrogen sulfide gas has many other names such as dihydrogen sulfide, sulfur hydride, hydrosulfuric acid, hepatic acid, and sulfurated hydrogen. The distinct smell that this chemical has also given it the name such as sewer gas, sour gas, swamp gas, and even stink damp. From the name itself, you can imagine, it is definitely not odorless.

Side Effects of Inhaling Hydrogen Sulphide Gas

This substance from the Sulfur category has been considered Harmful Chemicals Banned Under REACH. It has been recognized as dangerous in Europe, but not in yet in other countries. And that banned are just for common usage.

There are side effects if you inhale this substance that stats the level of severity of this chemical. That is why there are Side Effects Of Inhaling Cleaning Chemicals as well as inhaling Hydrogen Sulfide.

  • People exposed to hydrogen sulfide will not show any sign of serious risks from mild contamination. However, fatalities have been reported in accordance in a more severe condition.
  • This colorless, highly flammable with a tint of rotten eggs smell produced naturally by decaying organic element during the industrial processes. However, even if there is any exposure the sign is mild to none. Therefore, there is no adequate warning to the toxicity.
  • Some of the direct exposure side effects include olfactory fatigue, lung, and respiration issue. This condition varies in accordance to people condition. Hydrogen sulfide can be absorbed the lungs even though the cutaneous absorption is minimal to rough due to its systemic effects.
  • This substance is highly toxic gas which can be turned into liquefied or compressed into gas. Moreover, the slightly unique smell that the Uses Sulfur And Its Compound detectable as low as 0.5 ppb.
  • Inhalation is the major route that human get exposure to this compound which can rapidly be absorbed by the lungs. There are side effects that human often takes for granted. Even if the odor is quite a distance, and it is not an immediate warning of hazardous effects.

Skin/Eye Contact

The long term exposure to hydrogen sulfide, even in very relatively low levels. There will be a slight skin or eye issues.  It can cause result in painful dermatitis and a sense of burning eyes.

In the event of direct contact with the liquefied gas of hydrogen sulfide can cause frostbite. The condition where the body reacts to direct exposure of chemical with the freezing scheme. This can happen even if the contact through intact skin is minimal.


This substance come in a gas form that has no color which can be deadly in the room temperature.  Moreover, it is very toxic by inhaling of this substance. It will firstly show signs of influence in the out layer of the human body such as the eyes or the skin.

There is no sign of ingestion issue due to the compound. However, in long term exposure and the high dose of its content may affect the digestion. I’m mild exposure it is unlikely to occur. 


This mucous membrane with no color gives no warning to the irritation that it causes. Moreover, it also can irritate the respiratory tract and cause issues such as pulmonary edema. The condition that triggers immediate or delayed function of the edema. This side effect is valuable to occur due to after exposure to high concentrations.

Acute Exposure

There is a small gesture of exposure that describes the effect of this chemical on the human body. People will feel nausea, delirium, headaches, disturbed equilibrium, convulsions, and also tremors.

This is one of the reason Why Should An Individual Working With Chemicals Understand The Hazard when dealing with the chemical. This should be considered due to the fact that not many can link these symptoms to hydrogen sulphide exposure.

Extreme Exposure

Inhalation with a high concentration can produce extremely severe toxicity.

  • Rapid unconsciousness. The almost odorless subtance will likely make it too late to discover the chemical as the main reason for the condition.
  • Inhibition of the cytochrome oxidase enzyme system resulting due to there is not enough oxygen in the human body. Anaerobic metabolism will accumulate lactic acid result in an acid-base imbalance.
  • Nervous system and cardiac tissues problems because of its vulnerability to oxidative metabolism. it leads to serious respiratory arrest which typically causes death.


CNS injury happens almost instantly after exposure. It shows significantly if it comes in high concentrations. It only just take only a few breaths before a person loses consciousness. Other symptoms of side effects include coma, respiratory paralysis, seizures, and also death.

CNS stimulation can also lead to CNS depression. Moreover, it also includes signs such as excitation, headache, rapid breathing, impaired gait, dizziness, and possibly progress to respiratory paralysis. 


If someone accidentally inhales hydrogen sulfide initially it will affect the nose and throat first. Even at a very low level as much as 50 pp, it still can rapidly produce irritation of the throat, nose, and lower respiratory tract.

Furthermore, it can lead to pulmonary manifestations include breathing issues, cough, bronchial or lung hemorrhage. In a more severe dangerous level, things can worsen to health issues such as bronchitis, lungs issues, and blue skin color.

Potential Sequelae

Inflammation of the bronchi area can easily to late development. Any survivors of severe exposure to this chemical can develop various psychological disturbances. Moreover, it can also cause permanent damage to the brain and heart where the cornea itself may be permanently scarred.

Hydrogen sulfide accumulates in the body through inhalation. Nevertheless, repeated or long term exposure has been reported to cause several side effects. It ranges from mild to severe toxicity and even death.

The signs of exposure such as low blood pressure, nausea, headache, weight loss, loss of appetite, eye-membrane inflammation, and chronic cough are just a few. Furthermore, side effects on children may slightly different than an adult. It is among the many chemicals that actually Harmful Chemicals That Can Kill You. Therefore, the treatment is also varies depending on the symptoms. Seek medical advice immediately after the sign occurs.
