most dangerous greenhouse gas
It has an atmospheric life of 3,200 years and global warming potential 23,900 times stronger than carbon dioxide. SF6 is considered one of the most dangerous greenhouse gases known. It is banned as a tracer gas and is limited to high voltage applications. In addition, the US Department of Energy repaired leaks in several laboratories, thereby reducing emissions by 35,000 pounds a year.
Answer Wiki. It turns out that sulfur hexafluoride, SF6, is the most potent greenhouse gas ever measured. Greenhouse gas potency is measured with an unit called the GWP or global warming potential, and it takes in account the molecule's ability to absorb infrared radiation and survival in the atmosphere. SF6 is an octahedral molecule, with six S-F bonds, each capable of absorbing infrared radiation very well.
