Perfluorodecalin (PFD), is a perfluorocarbon - part of a group of chemicals closely related to PFASs, but quite different from PFASs in significant respects:
- Unlike PFAS molecules, which can include oxygen, hydrogen, sulfur and/or nitrogen atoms, perfluorocarbon molecules contain only carbon and fluorine atoms.
- Perfluorocarbons are used in and emitted from different applications and industries than PFASs are (e.g. more healthcare related applications involving the transport of oxygen).
- The effects of perfluorocarbons on human health and the environment are substantially different than the effects of PFASs:
-
- Perfluorocarbons are not toxic, and there are no direct health effects associated with exposures to them. The health effects and exposures information found on the Basic Information about PFASs page does not apply to perfluorocarbons.
PFD is a biocompatible material with a high affinity for oxygen and ability to dissolve large amounts of oxygen.
