• Coronavirus: Image showing sulphur dioxide forecasts falsely

    Since February 10, several media outlets – national and international – have published a report saying that an increase in sulfur dioxide levels in Wuhan and Chongqing is possibly linked with mass cremation of coronavirus victims. These reports include a screenshot of an image from w indy.com, a Czech-based weather service, as the primary source to show “sulfur dioxide levels in Wuhan were at a staggering 1,350 micrograms per cubic meter (µg/m3).”.

  • 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
