ECHEMI Editorial Reference

Hydrogen sulfide is generally found as a pungent colorless flammable gas, although it is commonly shipped as liquefied compressed gas (NIOSH, 2011). Its characteristic odor of “rotten eggs” cannot be considered indicative of its concentration, as olfactory fatigue occurs quite rapidly, even at relatively low concentration levels (100–150 ppm). It has a vapor density of 1.19, which makes it heavier than air and will cause it to accumulate in low lying areas rather than disperse easily in air and
Hydrogen Sulfide 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 where anaerobic digestion can take place. It also occurs in volcanic gases, “natural gas”, and some well waters. Hydrogen sulfide has numerous names, some of which are archaic.Small amounts of hydrogen sulfide occur in crude oil, but natural gas can contain up to 90%. About 10% of the total global emission of H2S is due to human activity.
Hydrogen sulfide is a colourless gas with strong odour of rotten eggs (odour threshold ca 0.2 ppt).
ChEBI: A sulfur hydride consisting of s single sulfur atom bonded to two hydrogen atoms. A highly poisonous, flammable gas with a characteristic odour of rotten eggs, it is often produced by bacterial decomposition of organic matter in the absence of oxygen.
ReproductiveEffector; Human Data. Hydrogen sulfide is used in the syn-thesis of inorganic sulfides, sulfuric acid, and organic sulfurcompounds; as an analytical reagent; as a disinfectant inagriculture; and in metallurgy. It is generated in many industrial processes as a by-product and also during thedecomposition of sulfur-containing organicmatter，sopotential for exposure exists in a variety of situations.Hydrogensulfide is found in natural gas, volcanic gas, andin certain natural spring waters. Its may also be encounteredin the manufacture of barium carbonate, barium salt, cello-phane，depilatories, dyes, pigments, felt, fertilizer, adhe-sives, viscoserayon, lithopone， synthetic petroleumproducts; in the processing of sugar beets; in mining, partic-ularly where sulfide ores are present; in sewers and sewagetreatment plants; during excavation of swampy or filledground for tunnels, wells, and caissons; during drilling ofoil and gas wells; in purification of hydrochloric acid andphosphates; during the low-temperature carbonization ofcoal; in tanneries, breweries, slaughterhouses; in fat render-ing; and in lithography and photoengraving.

Physical Properties:

H2S is soluble in carbon disulfide, methanol, acetone and alkanolamines. A solution of hydrogen sulfide in water is initially clear but over time turns cloudy. This is due to the slow reaction of hydrogen sulfide with the oxygen dissolved in water, yielding elemental sulfur, which precipitates out.

XLogP3:

0.5

Appearance:

Hydrogen sulfide appears as a colorless gas having a strong odor of rotten eggs. Boiling point -60.2°C. Shipped as a liquid confined under its own vapor pressure. Density (liquid) 8.3 lb / gal. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Gas is very toxic by inhalation. Fatigues the sense of smell which cannot be counted on to warn of the continued presence of the gas. Prolonged exposure of closed containers to heat may result in their violent rupturing and rocketing. Rate of onset: Immediate & Delayed Persistence: Minutes to hours Odor threshold: 0.1 ppm Source/use/other hazard: Disinfectant lubricant/oils; interm for HC manufacture; deadens sense of smell.

Toxicity:

Toxicity of hydrogen sulfide is most likely related to inhibition of metal-containing enzymes such as cytochrome oxidase, the final enzyme of the mitochondrial respiratory chain, and carbonic anhydrase. Therefore, hydrogen sulfide affects cellular energy production and respiration. Mucous membranes and tissues with a high oxygen demand, like nervous and cardiac tissues are most susceptible tissues in exposure to hydrogen sulfide. In addition, sulfide also seems to act on the respiratory drive through other mechanisms such as suppression of synaptic activity, inhibition of monoamine oxidase, a direct action on respiratory centers in the brain, and stimulation of the glutamate receptors in the brain. The hydrosulfide anion also forms a complex with methemoglobin and creates sulfmethemoglobin. On the other hand, hydrosulfide can be produced endogenously, particularly in mammalian cells, through an enzymatic pathway and in a smaller part via a nonenzymatic pathway. Among enzymes involved in hydrosulfide production, cystathionine- synthase and cystathionine-lyase have been investigated extensively; both use vitamin B6 as a cofactor. Captopyruvate sulfurtransferase along with cysteine aminotransferase are involved in transsulfuration and reverse transsulfuration pathways in different capacities and utilize specific substrates. Of course, the regulation mechanisms for the expression and activities of these hydrosulfide-generating enzymes under physiological or pathophysiological conditions needs more research. These enzymes are differentially expressed in neuronal, immune, cardiovascular, renal, gastrointestinal, reproductive, respiratory, liver, and endocrine systems and affect the functions of these systems through production of hydrosulfide. Meanwhile, different molecular targets, such as different ion channels and signaling proteins, mediate physiological functions of hydrogen sulfide. Alternations of hydrosulfide metabolism lead to an array of pathological disturbances in the form of hypertension, diabetes, cirrhosis, atherosclerosis, heart failure, inflammation, sepsis, erectile dysfunction, asthma, and neurodegenerative disease.

Flammability characteristics:

Hydrogen sulfide is flammable in air in the range of 4.3 to 45.5% (NFPA rating = 4). Combustion products (sulfur oxides) are also toxic by inhalation. In the event of a hydrogen sulfide fire, stop the flow of gas if possible without risk of harmful exposure and let the fire burn itself out.

Explosive limit:

Strong rotten egg odor detectable at 0.001 to 0.1 ppm (mean = 0.0094 ppm); olfactory fatigue occurs quickly at high concentrations

Sweetish taste

Air and Water Reactions:

Highly flammable; a flame can very easily flash back to the source of leak. Soluble in water to a maximum of 0.4% by mass at room temperature .
