• Coronavirus: Wuhan cremation claims debunked as experts

    Feb 26, 2020 · On February 9, a Twitter user shared a satellite visualization that showed a spike in levels of SO2 mass around Wuhan—the Chinese city suspected to be the origin of the deadly virus. The user claimed that SO2 levels are "commonly associated with the burning of organic matters", suggesting that it could be the result of dead bodies being burned on the outskirts of the city.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
