New evidence shows blood or plasma donations can reduce the PFAS 'forever chemicals' in our bodies
You might have heard of PFAS, a synthetic chemical found in certain legacy firefighting foams, non-stick pans, carpets, clothes and stain- or water-resistant materials and paints.
PFAS stands for "per- and poly-fluorinated alkyl substances." These molecules, made up of chains of carbon and fluorine atoms, are nicknamed "forever chemicals" because they don't degrade in our bodies.
There is global concern about PFAS because they have been used widely, are persistent in the environment and accumulate in our bodies over time.
There was no way to reduce the amount of PFAS found in the body—until now.
Our new randomized clinical trial, published in the journal JAMA Network Open, has found regularly donating blood or plasma can reduce blood PFAS levels.
What's the concern about PFAS chemicals?
The science is unresolved around what levels of PFAS exposure, if any, are safe.
