Hydrogen sulfide is a chemical compound ... be exposed to hydrogen sulfide by being near waste water treatment ... victims of carbon monoxide poisoning. ...
4-Dimethylaminophenol has been used as an antidote for cyanide poisoning. [1] It has also been shown to be effective in treating hydrogen sulfide toxicity. [2] It works by generating methemoglobin. [3] This is suitable as an emergency treatment only; treatment must be followed up with sodium thiosulfate or cobalamin.
Sulfur medications such as phenacetin, metoclopramide, dapsone, phenzopyridine, and trimethoprim-sulfamethoxazole; hydrogen-sulfide-producing intestinal bacteria, such as Morganella morganii: Risk factors: Pulmonary arteriovenous malformation: Prevention: Avoidance of sulfur-containing compounds including drugs: Treatment: Blood transfusions
Sewer gas can contain methane and hydrogen sulfide, both highly flammable and potentially explosive substances. As such, ignition of the gas is possible with flame or sparks. [ 7 ] The methane concentration in open sewers is lower (7 to 15 ppmv) than the closed drains (up to 300 ppmv) in samples collected 2 cm (0.8 in) above the level of sewage.
The report contains discussion of various harmful chemicals "likely to be present" in the waste—sodium hydroxide, cobalt phthalocyanine sulfonate, coker naphtha, thiols, sodium alkanethiolate, sodium hydrosulfide, sodium sulfide, dialkyl disulfides, hydrogen sulfide—and notes that some of these "may cause harm at some distance".
Hydrogen sulfide: Hydrogen sulfide poisoning: Hydrogen sulfide is associated with sour natural gas, crude oil, anoxic water conditions and sewers (more information needed). hydrogen sulfide is present in some lakes and caves and can also be absorbed through the skin.

An example of histotoxic hypoxia is cyanide poisoning. There is a profound drop in tissue oxygen consumption since the reaction of oxygen with cytochrome oxidase is blocked by the presence of cyanide. Cyanide binds to the ferric ion on cytochrome oxidase a 3 and prevents the fourth and final reaction in the electron transport chain.
When the hydrolysis of calcium sulfide is accounted for, the individual reactions for each of the by-products are: 1 / 2 S 8 + H 2 O + 2 Ca(OH) 2 → 2 H 2 S + CaS 2 O 3 3 / 8 S 8 + H 2 O + 2 Ca(OH) 2 → 2 H 2 S + CaSO 3 1 / 2 S 8 + 2 H 2 O + 2 Ca(OH) 2 → 3 H 2 S + CaSO 4. However, elemental sulfur can undergo a disproportionation reaction ...
