Hi Reddit! This is Tiffany from Bloomberg and I am joined by Dr. Philippe Grandjean of Southern Denmark University here. In a new documentary, I interviewed Dr. Grandjean on how substances known as PFAS, or "forever chemicals," found their way to every corner of the planet-and the consequences.

You can watch it here: https://youtu.be/t8qGtEVh7oQ?si=QNjv4-IorQrCtpL4

PFAS are used in hundreds of everyday products-from fabric protectors, electronics and non-stick pans to foams, tapes and even toilet paper. PFAS are called "forever chemicals" because the properties that make them so useful to consumers make them very persistent in the environment.

In the Bloomberg Originals video documentary The Poison In Us All, we reveal how the chemicals - which have been linked to cancer and are the subject of sweeping litigation - ended up inside the bodies of almost everyone on the planet.

Litigation has revealed documents showing that its manufacturers, including industrial giant 3M, had dumped the chemicals for years and have been aware of the dangers associated with PFAS. 3M has said its products "are safe and effective for their intended uses" and assailed plaintiffs' lawyers for selectively citing documents to portray "an incomplete and misleading story about 3M's actions."

We'll be on at 1pm ET (18 UT), ask me and Dr. Grandjean any questions you have about PFAS here!
