Atmospheric Sulfr hexafluoride: Trends, Sources, and Prospects

Sulfur hexafluoride (gaz sf6) 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, sf 6 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 reductionGet price
