PFBA is a breakdown product of other PFAS that have been used in stain-resistant fabrics, paper food packaging, carpets, and consumer products.

This was found in a study from the DTU National Food Institute carried out in collaboration with the Danish Veterinary and Food Administration.

While GenX was not found in the blood samples of Cape Fear River basin residents, three PFAS unique to the Chemours Fayetteville Works facility were in the blood of almost everyone who participated in the 2020-2021 study.
