The global market for chemicals from fluorine was about US$16 billion per year as of 2006. [1] The industry was predicted to reach 2.6 million metric tons per year by 2015. [2] The largest market is the United States. Western Europe is the second largest. Asia Pacific is the fastest growing region of production. [2]
The EPA issued health advisories for four specific PFASs in June 2022, significantly lowering their safe threshold levels for drinking water. PFOA was reduced from 70 ppt to 0.004 ppt, while PFOS was reduced from 70 ppt to 0.02 ppt. A safe level for the compound GenX was set at 10 ppt, while that for PFBS was set at 2000 ppt. While not ...
The data are to be collected during 2023 to 2025. The agency may use the monitoring data to develop additional regulations. [117] [118] 13 April 2022 14 State Attorneys General signed a letter to the EPA urging the agency to use its current-year funding to "meet commitments and deadlines outlined in its PFAS Strategic Roadmap".

In order to combat the potential global warming effects of F-gases, and as part of the EU's Kyoto protocol commitments, in 2006 the European Union passed two pieces of legislation controlling their use: the F-gas Regulation (EC) No 842/2006 and the Mobile Air Conditioning Directive Directive 2006/40/EC. The F-gas Regulation adopts an approach ...

Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...
Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen [note 1] and exists at standard conditions as pale yellow diatomic gas. Fluorine is extremely reactive as it reacts with all other elements except for the light inert gases. It is highly toxic.
