- n. Plural form of perfluorocarbon.
“But researchers have recently shown that by ventilating a preemie with fluids called perfluorocarbons, they can supply oxygen to the tissues without damaging the lungs.”
“Some GHGs, such as perfluorocarbons and sulphur hexafluoride, have estimated lifetimes of many thousands of years in the atmosphere.”
“Fluorinated gases (or High Global Warming Potential gases): This group of gases, which includes hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride, are “synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes.””
“Blackburn's bill, H.R. 97, states: "The term 'air pollutant' shall not include carbon dioxide, water vapor, methane, nitrous oxide, hydrofluorocarb ons, perfluorocarbons, or sulfur hexafluoride.”
“In addition to carbon dioxide, emissions of methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride would count toward a facility's greenhouse gas emissions.”
“This process also breaks off bits of the fluorine from the cryolite, which escapes the smelter in the form of perfluorocarbons PFCs—these are the most noxious of greenhouse gases, trapping thousands of times more heat than carbon dioxide.”
“Besides coal- and gas-fired power plants, other industries that could have been affected are chip makers, which use perfluorocarbons, or pfcs, in their industrial processes.”
“After a scientific analysis of carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride, the EPA then made an extraordinary decision in April to propose a ruling to recognize greenhouse gases as a cause of climate change and an accountable threat to public welfare.”
“The bill gives EPA authority to set up a similar system for perfluorocarbons (PFCs).”
“The other five gases are methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.”
