Abstract:
Im Rahmen dieser Arbeit wurden sedimentologische und geochemische Untersuchungen an Oberflächensedimenten der Deutschen Bucht NW von Helgoland durchgeführt. Die chemischen Analysen zeigten, daß in den Pelitfraktionen der fein sandigen bis mittelsandigen Sedimente z. T. erhöhte Schwermetallkonzentrationen anzutreffen sind. Diese Anreicherungen sind auf die Einbringung von Dünnsäure ins Meerwasser als Abfallprodukt der Titandioxidgewinnung zurückzuführen, wie Korrelationen einzeln untersuchter Elemente zeigen.
