[quote:Anonymous Coward 32800786:MV8yMTE3NzM3XzM1NzE0MDA0XzFGMDREM0ND] [quote:Anonymous Coward 11326620:MV8yMTE3NzM3XzM1NzEzOTI5X0MxODVDRUM1] Just looked up some of the side-affects of this quote "harmless" gas: http://www.atsdr.cdc.gov/mmg/mmg.asp?id=221&tid=40 Methyl mercaptan gas is irritating to the eyes, skin, and respiratory tract. Edema of the airway and lungs can occur. Other possible effects include headache, dizziness, tremors, and seizures, and nausea and vomiting, and lack of coordination. The gas is rapidly absorbed in the lungs. Skin and eye absorption are minimal; however, upon direct contact with eyes or skin, liquified methyl mercaptan will likely cause frostbite injury. Methyl mercaptan is a central nervous system depressant that acts on the respiratory center to produce death by respiratory paralysis. Individuals with pre-existing respiratory, cardiac, nervous system, or liver impairment may be more susceptible to exposure to methyl mercaptan. Acute Exposure Methyl mercaptan inhibits mitochondrial respiration by interfering with cytochrome c oxidase. It also inhibits several enzyme systems such as carbonic anhydrase, beta-tyrosinase, and sodium+, potassium+ATPase. The enzyme inhibition appears to be related to a thiol-metal interference. Children do not always respond to chemicals in the same way that adults do. Different protocols for managing their care may be needed. Respiratory Acute inhalation exposure can irritate the mucous membranes of the respiratory tract. This may cause cough, dyspnea, a sensation of tightness of the chest, and subsequent cyanosis. Respiratory depression, apnea, and pulmonary edema were observed in animals. Children may be more vulnerable to gas exposure because of relatively higher minute ventilation per kg and failure to evacuate an area promptly when exposed. Hematologic Severe hemolytic anemia may occur in people with glucose-6-phosphate dehydrogenase deficiency. Neurologic Restlessness, headache, staggering, and dizziness may develop; severe exposure may lead to convulsions and coma. Dermal Frostbite injury can occur from contact with the liquified gas. Because of their relatively larger surface area:weight ratio, children are more vulnerable to toxicants that may affect the skin. Ocular/Ophthalmic High concentrations of methyl mercaptan can cause eye irritation. Gastrointestinal Although ingestion is unlikely, irritation of the mouth, throat, and esophagus are possible. Nausea and vomiting may occur even with inhalation exposure to the gas. Potential Sequelae Methyl mercaptan exposure may result in altered heme synthesis. [/quote] Wow, that is truly shocking. So much for 'harmless gas' eyy. [/quote]

Staff at a chemicals factory in north-western France are working to stop a gas leak that has spread a foul smell to Paris and south-east England.
