High concentrations of perfluorohexanoic acid were readily extractable from the surfaces of "smart" and "fitness" watch bands, particularly from the more expensive ones.
The article from Medscape discusses a study revealing that fitness watch bands, particularly those made from rubber or plastic, contain high levels of perfluorohexanoic acid (PFHxA), a type of per- and polyfluoroalkyl substance (PFAS). These "forever chemicals" are known for their persistence in the environment and potential health risks, including links to cancer, thyroid disease, and immune system issues. The study, published in Environmental Science & Technology, found that PFHxA levels in these bands were significantly higher than in other consumer products, with concentrations up to 100 times greater than in other items like cosmetics or textiles. The researchers suggest that the close contact of these bands with the skin could lead to dermal absorption, posing health risks. They recommend that manufacturers consider using alternative materials or treatments to reduce PFAS content in fitness wearables.
