PFAS in Apple Watch Bands

solo loops are silicone, sport bands are fluoroelastomer which by definition may contain some PFAs. I am confident that my fluoroelastomer sport band is the best and most comfortable strap I have ever worn in 60 years of watch wearing.

The recent academic study you are implicating is

https://pubs.acs.org/doi/10.1021/acs.estlett.4c00907

which lacks any per manufacturer data or any real evidence that any PFAs have ever been absorbed in practice. They had to use solvents to extract them.

According to the page below, the Sports Loop bands contain:

Tech Specs - Material: 100% recycled nylon, 100% recycled polyester, 100% recycled spandex

40mm Plum Sport Loop - Apple

There is no mention of PDAS. If this does not answer your question, please contact Apple Support.

So is mine , I'm not worried by this kind of study, same as I didn't stop using saccharin sweeteners because feeding a stomach load to rats every day might give them cancer.

There's more data if you scroll down to "Supporting Information" and click on (PDF). Clicking on the URL does nothing.

I was hoping my ACS login would get me the full article but, as it's not a paid membership, it doesn't.

Yes a shame they didn't publish full results naming which brands had which results. I wonder why that was. My Apple Watch Sport Band is Fluoroelastomer so I assume it was one that was affected.

I would like to see the analysis of a swab taken from human wrist after 24 hours of wearing rather than solvents on the strap.
