Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11]
Mercaptan is a harmless chemical that smells like sulfur or rotten eggs that utility companies add to natural gas to make it easier to detect leaks, according to Healthline, a medical information ...
[3] [4] Because natural gas is odorless, odorizers such as mercaptan (which smells like rotten eggs) are commonly added to it for safety so that leaks can be readily detected. [ 5 ] Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) [ 6 ] decompose under anaerobic conditions and are ...
Los Angeles County officials attribute the foul odor to a toxic, colorless gas called hydrogen sulfide. An invisible gas that smells like 'rotten flesh sitting in the sun' is causing headaches and ...
It has now been demonstrated that methyl mercaptan, dimethyl sulfide, and hydrogen sulfide (described as decomposing vegetables, unpleasantly sweet/wild radish and rotten eggs respectively) are all present in human flatus in concentrations above their smell perception thresholds.
Prolonged exposure to relatively low levels of nitrogen (II) oxide may cause persistent headaches and nausea. [18] Like chlorine gas poisoning, symptoms usually resolve themselves upon removal from further nitrogen dioxide exposure, unless there had been an episode of severe acute poisoning. [19] Treatment and management vary with symptoms.
Overexposure to phosphine gas causes nausea, vomiting, abdominal pain, diarrhea, thirst, chest tightness, dyspnea (breathing difficulty), muscle pain, chills, stupor or syncope, and pulmonary edema. [37] [38] Phosphine has been reported to have the odor of decaying fish or garlic at concentrations below 0.3 ppm. The smell is normally restricted ...
Thioacetone has an intensely foul odor. Like many low molecular weight organosulfur compounds, the smell is potent and can be detected even when highly diluted. [5] In 1889, an attempt to distill the chemical in the German city of Freiburg was followed by cases of vomiting, nausea, and unconsciousness in an area with a radius of 0.75 kilometres (0.47 mi) around the laboratory due to the smell.
