    The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.
