Abstract

We compared the plasma concentration of 13 perfluorinated contaminants (PFCs) in five sea turtle species. Perfluorooctane sulfonate (PFOS) was predominant in most species, except hawksbills had higher concentrations of perfluorononanoate. Excluding spongivorous hawksbills (11.9 ng/g), respective mean PFOS concentrations (2.41, 3.95, 6.47, and 15.7 ng/g) related to understood trophic level of herbivorous greens, jellyfish-eating leatherbacks, and omnivorous loggerheads and Kemp’s ridleys, indicating that PFCs biomagnify in marine food webs.
