Study Reveals High Levels of Ultrashort-Chain PFAS in Wilmington Residents' Blood
A recent study by NC State found that residents in Wilmington, North Carolina, had high levels of ultrashort-chain PFAS in their blood before the GenX scandal.
Archived blood samples from 2010 to 2016 showed that two ultrashort-chain compounds, TFA and PFMOAA, were present in nearly every sample, making up close to half of all PFAS measured.
“Finding these tiny compounds at such high levels changes our understanding of exposure,” said Dr. Jane Hoppin, who leads NC State’s GenX Exposure Study. “They were assumed to pass through the body quickly, but sustained exposure through drinking water appears to have driven accumulation.
The study raises fresh questions about the safety of replacement chemicals used after GenX.
