Study: Novel PFAS comprise 24% of those measured in blood of Wilmington, N.C. residents
News
23 Jul 2020 | NC State News
The fluoroethers – Nafion byproduct 2, PFO4DA and PFO5DoA – these are the first measurements of these chemicals in humans. Two other fluoroethers, PFO3OA and NVHOS, were infrequently detected. Nearly all samples had at least one fluoroether present, but GenX was not found in any samples.

Are feathers of a songbird model species (the great tit: ) suitable for monitoring perfluoroalkyl acids (PFAAs) in blood plasma?
Science
14 Jul 2020 | Environ. Sci. Technol.
Results suggest that feathers cannot be used to estimate PFOA and PFOS concentrations in blood plasma, except when there is a great deal of variation in pollutant concentrations among sites/individual birds.
