| contents | A 3.38 m long sediment core raised from the tidal flat sediments of the 'Blauortsand' in the Wadden Sea northwest of Büsum (Schleswig-Holstein, Germany) was analysed in order to investigate long term changes in sediment pollution with Pb, Cu, Zn and Cd. Comparison with the topographic maps since 1952 and 210Pb activity allowed a general dating of the sediment succession in the core. The heavy metal concentrations including 210Pb of the < 20 µm grain-size fraction in thick sediment slices below 1.30 m indicated background niveaus. Their values increased and reached modern levels in the upper sediment layers of the core above 1 m. The increments for Pb, Cu, Zn was 1 to 3 fold and Cd up to 11 fold since the second half of the 19th century. More investigations are needed to quantify the geographical extent and history of the contaminations shown in this pilot study. |
