2017/8/243. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.

Abstract. A rapid headspace method for the simultaneous laboratory determination of intentionally introduced hydrologic tracers, sulfur hexafluoride (SF6), trifluoromethyl sulfur pentafluoride (SF5CF3), Halon 1211 (CF2ClBr), and other halocarbons in water and gases is described. The high sensitivity of the procedure allows for introduction of

Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901.
