• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years. [29] Measurements of SF 6 show that its global average mixing ratio has reached over 10 parts per trillion (ppt) as of April 2020, and is increasing by about 0.35 ppt (3.5 percent) per year.
