In order to assess pollution with large microplastics (L-MP, 500-5000 µm) in the Lower Weser and transition to the German North Sea, surface water samples were collected with the RV Otzum (ICBM, Institute for Chemistry and Biology of the Marine Environment), as well as with the RV Uthörn (AWI, Alfred-Wegener-Institute) in April 2018. Sampling was performed using a microplastic net (mesh size: 300 µm), followed by filtration in the laboratory over a 500 µm stainless steel sieve. Putative MP items in the size range 500-5000 µm were analysed by means of Attenuated Total Reflection - FTIR in order to determine the underlying synthetic polymer. Dominant polymer type in the L-MP sample fraction was polyethylene. Concentrations ranged between 1 × 10⁻² m⁻³ and 9.8 × 10⁻¹ m⁻³. The highest MP concentration was measured upstream the Weser Weir.
In order to assess pollution with small microplastics (S-MP, 11-500 µm) in the Lower Weser and transition to the German North Sea, surface water samples were collected with the RV Otzum (ICBM, Institute for Chemistry and Biology of the Marine Environment), as well as with the RV Uthörn (AWI, Alfred-Wegener-Institute) in April 2018. Sampling was performed using a pumping system containing of a floating suction basket (mesh size: 500 µm) for pre-filtration, followed by the concentration onto a 15 µm stainless steel screen. Samples were isolated from the filter screens in the laboratory, thoroughly processed and measured via µFTIR imaging. Dominant polymer type in the S-MP sample fraction was acrylates/polyurethanes/varnish, and concentrations ranged between 2.3 × 10¹ and 9.7 × 10³ m⁻³, with maximum values in the area of the turbidity Maximum Zone of the River Weser.
