Novel PFAS Comprise 24% of Those Measured in Blood of Wilmington, North Carolina Residents

In a new paper detailing findings from North Carolina State University's GenX Exposure Study, researchers detected novel per- and polyfluoroalkyl substances (PFAS) called "fluoroethers" in blood from residents of Wilmington, North Carolina. The fluoroethers — Nafion byproduct 2, PFO4DA and PFO5DoA — represented 24% of the total PFAS detected in the blood of Wilmington residents and appear to leave the body faster than legacy PFAS. These are the first measurements of these chemicals in humans. The GenX Exposure Study began in 2017 after North Carolina State researchers found a chemical called GenX in Wilmington residents' drinking water. An upstream chemical facility
