    Abstract
    (PFAAs) are global environmental contaminants. PFOS and PFOA are chemically and biologically inert and very stable (Poulsen et al. 2005). PFOS meets the P (Persistent) and vP (very Persistent) criteria due to slow degradation. PFOS is also bioaccumulative (B) and toxic (T) (OSPAR 2005). PFOA is considered very persistent (vP) and toxic (T) (Van der Putte et al. 2010). PFOA also has the capacity to undergo long-range transportation. Per- and polyfluoroalkylsubstances (PFAS) can bind to serum albumin and accumulate in blood and organs (Jones et al., 2003). Accumulation in the marine food web starts from the bottom of the food chain, with invertebrates such as zooplankton and molluscs, followed by crustaceans, and then fish (Van de Vijver et al., 2003). The highest PFAS concentrations have been found in blood and internal organs (e.g. liver, kidney) of top predators, such as marine mammals (Martin et al., 2004; Ahrens et al., 2009) and fish‐eating birds (Kannan et al., 2001).
