A new study found 15 bands commonly available in the U.S. contained PFAS Smart Watch Bands Contain 'Very High Concentrations’ of Forever Chemicals That May Be Absorbed into Skin Skip to main content
“A significant fraction of short-chain PFAS deposited on the skin can migrate into the dermis, and some fraction will actually enter the bloodstream after passing through our skin,” Peaslee says.
The relationship between wearing rings and the transmission of microorganisms is still unclear. The Centers for Disease Control and Prevention guideline has categorized this as an "unresolved issue" in need of additional research; [1] the draft WHO guidelines also do not have a stated recommendation against the wearing of rings but note that "the consensus recommendation is to discourage the ...
Workers who handle PFAS-containing products can also be exposed during their work, such as people who install PFAS-containing carpets and leather furniture with PFAS coatings, professional ski-waxers using PFAS-based waxes, and fire-fighters using PFAS-containing foam and wearing flame-resistant protective gear made with PFASs.

But “many PFAS are only slowly excreted from our bodies, which causes them to build up to higher concentrations over time,” says Scott Bartell, Ph.D., a professor of environmental and ...
Perfluorodecanoic acid (PFDA) is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature. Over the last decades they have been used in consumer products and industrial applications.
Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
PFPE-D is synthesized by anionic ring-opening polymerization of 2,2,3,3-tetrafluorooxetane. PFPE-A is obtained by an initial esterification of polyethylene glycol with a perfluoroacyl fluoride. Then, it is converted into a fully fluorined polymer using direct fluorination. [3] [7] Structural formulas of different types
