Re: sulper fumes

If you want sulphur fumes try having a shower in bore water from the Great Artesian Basin. It is the town water for many central Queensland towns and when heated smells of Sulphur

Re: sulper fumes

Sulphur Dioxide is quite pungent. Hydrogen sulphide is the 'rotten egg' smell. If anyone visits Rotorua in New Zealand they get to know hydrogen sulphide very soon after arrival but fortunately after a while your nose becomes 'acclimatised' and you don't notice it any more.

Re: sulper fumes

I had experience of H2S while working in the oil industry where it can present a serious risk. Hydrogen Sulphide is a lethal poison which can kill very quickly in high concentrations. The fact that low concentrations can be tolerated and indeed mask the smell is a risk factor in that the concentration may increase without you being aware of it because you can no longer smell it. It's one of the risks associated with oil exploration and has been responsible for many deaths.


This from wikipedia


Hydrogen sulfide is a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of carbon monoxide. It binds with iron in the mitochondrial cytochrome enzymes, thus preventing cellular respiration.
Since hydrogen sulfide occurs naturally in the body, the environment, and the gut, enzymes exist to detoxify it. At some threshold level, believed to average around 300–350 ppm, the oxidative enzymes become overwhelmed. Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm. Detoxification is effected by oxidation to sulfate, which is harmless. Hence, low levels of hydrogen sulfide may be tolerated indefinitely.
Diagnostic of extreme poisoning by H2S is the discolouration of copper coins in the pockets of the victim. Treatment involves immediate inhalation of amyl nitrite, injections of sodium nitrite, or administration of 4-dimethylaminophenol in combination with inhalation of pure oxygen, administration of bronchodilators to overcome eventual bronchospasm, and in some cases hyperbaric oxygen therapy (HBOT). HBOT has clinical and anecdotal support.


Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema). These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic. These symptoms usually go away in a few weeks.



Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness. Chronic exposure to low level H2S (around 2 ppm) has been implicated in increased miscarriage and reproductive health issues among Russian and Finnish wood pulp workers, but the reports have not (as of circa 1995) been replicated.



Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis, degeneration of the basal ganglia and cerebral edema. Although respiratory paralysis may be immediate, it can also be delayed up to 72 hours.




I'd keep well away from it.
