Atmospheric sf 6: Trends, Sources, and Prospects

Sulfur hexafluoride (sf6 gas) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, Sulfr hexafluoride will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought sf6 gas into the climatic impact discussion aimed at reduction
