Salon.com : According to the Silicon Valley Toxics Coalition, the gas sulfur hexafluoride, commonly employed to clean reactors in silicon production, is considered by the Intergovernmental Panel of Climate Change to be “the most potent greenhouse gas per molecule; one ton of sulfur hexafluoride has a greenhouse effect equivalent to that of 25,000 tons of carbon dioxide.”
