How do dermal absorption percentages from 3D skin models compare with in vivo human dermal studies for PFOA and short‑chain PFAS?

In vitro 3D human skin equivalent models report substantially higher dermal uptake fractions for many PFAS—including a PFOA permeation of ~13.5% with ~38% retained in skin and much larger fractions fo...

What independent studies exist measuring PFAS transfer from smartwatch bands to human skin?

Independent research directly measuring PFAS transfer from smartwatch bands to living human skin is extremely limited: the University of Notre Dame team measured high, extractable PFAS in bands but di...
