      tissues of Giant Mud Crab following exposure under natural conditions in the

AB  - Poly and perfluorinated alkyl substances (PFASs) are persistent organic 
      pollutants (POPs) that are highly resistant to environmental degradation, and 
      have been detected in a broad range of terrestrial and aquatic species. Portunid 
      crabs have been shown to accumulate comparatively high concentrations of PFASs, 
      but previous work examining depuration in crabs was inconclusive. Here, we 
      trialled a novel experimental design to study depuration of PFASs from edible 
      tissues of portunid crabs, using paired claw samples, and trial this design with 
      Giant Mud Crab Scylla serrata exposed to the contaminant under natural 
      conditions. We found evidence for depuration of perfluorooctane sulfonate (PFOS), 
      perfluorohexane sulfonate (PFHxS) and perfluorooctanoic acid (PFOA), but with 
      depuration half-lives as high as 40 days (for PFOS). We also observed substantial 
      variability in the data, including differences in PFAS concentrations between 
      claws from the same individuals, potentially resulting from claw loss and 
      re-growth prior to capture. These results have broad implications for assessing 
      and minimising exposure risk in seafood species.
