Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of man-made chemicals that are persistent and highly stable in the environment. Fish consumption has been identified as a key route of PFAS exposure for humans. However, routine fish monitoring targets only a handful of PFAS, and non-targeted analyses have largely only evaluated fish from heavily PFAS-impacted waters.

Article Synopsis
  • PFAS are persistent man-made chemicals found in fish, mainly from recreational and drinking water sources, which pose potential health risks to humans.
  • A study in central North Carolina detected 36 different PFAS in fish fillets using advanced analytical methods, revealing 19 PFAS that traditional methods would miss.
  • Median levels of a specific PFAS, PFOS, were significantly high in the samples, indicating a need for broader monitoring and inclusion of non-targeted analyses in fish safety studies, especially in areas not previously deemed contaminated.

Central North Carolina (NC) is highly contaminated with per- and polyfluoroalkyl substances (PFAS), in part due to local fluorochemical production. Little is known about the exposure profiles and long-term health impacts for humans and animals that live in nearby communities. In this study, serum PFAS concentrations were determined using liquid chromatography high-resolution mass spectrometry and diagnostic clinical chemistry endpoints were assessed for 31 dogs and 32 horses that reside in Gray's Creek NC at households with documented PFAS contamination in their drinking water.

Per- and polyfluoroalkyl substances (PFAS) are a diverse class of synthetic chemicals that accumulate in the environment. Many proteins, including the primary human serum transport protein albumin (HSA), bind PFAS. The predictive power of physiologically based pharmacokinetic modeling approaches is currently limited by a lack of experimental data defining albumin-binding properties for most PFAS.
