• 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.
