    Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.

    that finally proved successful was to release the SF6 directly from a SF6 lecture bottle through a 0.006-inch hole in the lecture bottle cap (see fig. 3). The small hole resulted in a fine jet spray of the SF, that mixed well with the mine air. Mixing was further aided by moving the lecture bottle rapidly around the airway during release.
