Assessment of perfluorinated compounds (PFCs) in plasma of bottlenose dolphins from two southeast US estuarine areas: Relationship with age, sex and geographic locations

► Age and geographic location were the main influences on plasma PFC concentrations in dolphins. ► ∑PFCs, ∑PFCAs and ∑PFSAs declined significantly with age. ► Site-specific exposures with significantly higher plasma PFCs levels in SC than FL dolphins.
