New insights in distribution and accumulation patterns between various perfluorochemicals
Although more information becomes available on the distribution of perfluorinated compounds (PFCs) in marine mammals, it is for the first time that animals from the Dutch Wadden Sea are analysed. Liver, kidney, blubber, muscle and spleen tissue of stranded harbour seals (Phoca vitulina) at the islan...

Although more information becomes available on the distribution of perfluorinated compounds (PFCs) in marine mammals, it is for the first time that animals from the Dutch Wadden Sea are analysed. Liver, kidney, blubber, muscle and spleen tissue of stranded harbour seals (Phoca vitulina) at the island Texel, were evaluated on their fluorinated contamination burden and stable isotope measurements were conducted on muscle tissue. This study gives proof of renovation due to the analysis of different tissues from the same animal and due to the detection of some short- and long-chained perfluorochemicals. Perfluorooctane sulfonate (PFOS) was the predominant compound in all seal samples measured (ranging from 8.85 to 2724 ng.g-1wet weight), although large variations between tissues were monitored. To our knowledge, it is for the first time, that perfluorobutane sulfonate (PFBS) could be found at detectable concentrations (2.34 ± 0.68 ng.g-1 w wt) in wildlife.
