Updates & Corrections

  • Correction 01 August 2023: The graphic ‘Fluorinated world’ incorrectly stated that TFA is a greenhouse gas. It isn’t. The graphic has now been updated.

  • Clarification 11 September 2023: An earlier version of this News feature implied that all of the fluorosurfactants used to create fluoropolymers are toxic. In fact, not all have been tested for toxicity. It also stated that the only option to clean up TFA will be reverse osmosis, but alternative methods could be viable in the future.

  • Correction 07 November 2023: An earlier version of this article incorrectly implied that all fluoropolymers are created using fluorosurfactants.
