Abstract: | Recent scientific research on perfluorinated surfactants (PS) revealed their ocurrence in German surface and drinking waters (Skutlarek, Exner, Färber 2006). Since several years, PS have been found in the global environment, especially in animal and human tissues. PS possess extreme persistence against microbiological and chemical degradation and are able to bioaccumulate in animals and humans (Houde et al. 2006). PS concentrations (sum of 12 components) in the Rhine river and its main tributaries were determined below 100 ng/L, but the rivers Ruhr (tributary of the Rhine) and Möhne (tributary of the Ruhr) showed remarkable high concentrations (Ruhr: up to 446 ng/L, Möhne: up to 4385 ng/L). The maximum concentration in drinking waters was 598 ng/L with the major component perfluorooctanoic acid (PFOA). The PS concentrations decreased similarly to the PS concentrations of the raw waters along the flow direction of the Ruhr river. Therefore it seems to be necessary to install legal regulations for these compounds. |
