Sustained growth of sulfur hexafluoride emissions in China inferred from atmospheric observations [PDF]

open access: yesNature Communications
Sulfur hexafluoride (SF6) is a potent greenhouse gas. Here we use long-term atmospheric observations to determine SF6 emissions from China between 2011 and 2021, which are used to evaluate the Chinese national SF6 emission inventory and to better ...

Declining, seasonal-varying emissions of sulfur hexafluoride from the United States [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Sulfur hexafluoride (SF6) is the most potent greenhouse gas (GHG), and its atmospheric abundance, albeit small, has been increasing rapidly. Although SF6 is used to assess atmospheric transport modeling and its emissions influence the climate for ...

Sulfur Hexafluoride Gas Leakage Monitoring and Early-Warning Method for Electrical Power Facilities

open access: yesIEEE Access, 2020
Most transformer substations in power supply facilities rely on sulfur hexafluoride electrical equipment. A sulfur hexafluoride gas leak can cause serious health concerns if effective measures are not adopted in time.

Exposure to Sulfur Hexafluoride Influences Viability in Cell Transplant Suspensions [PDF]

open access: yesBioTech
Cell transplantation is often performed with ultrasonographic guidance for accurate delivery through injection. In such procedures, using ultrasonographic contrast greatly improves target delivery. However, accumulating evidence suggests that exposure to

Case Series of Inappropriate Concentration of Intraocular Sulfur Hexafluoride [PDF]

open access: yesCase Reports in Ophthalmology, 2018
Due to high complexity, vitreoretinal surgery presents a higher number of patient safety incidents compared with other ophthalmic procedures. Intraocular gases are one of the most useful adjuncts to vitrectomy and surprisingly, surgeons commonly admit to

Simultaneous sulfur hexafluoride and nitrogen multiple-breath washout (MBW) to examine inherent differences in MBW outcomes. [PDF]

open access: yesERJ Open Res, 2019
Multiple-breath washout (MBW) can be performed with different gases (sulfur hexafluoride (SF6) and nitrogen (N2)) and different devices, all of which give discrepant results. This study aimed to confirm previously reported differences and explore factors
