Tissue distribution of perfluorinated chemicals in harbor seals ( Phoca vitulina ) from the Dutch Wadden Sea
Perfluorinated acids (PFAs) are today widely distributed in the environment, even in remote arctic areas. Recently, perfluorooctane sulfonate (PFOS) has been identified in marine mammals all over the world, but information on the compound-specific tissue distribution remains scarce. Furthermore, alt...

Perfluorinated acids (PFAs) are today widely distributed in the environment, even in remote arctic areas.
