Summary

Beach litter and microplastics (20-5000 microns) were co-assessed along the Baltic Sea coast of Schleswig-Holstein in spring and autumn 2018, finding no correlation between macro and microplastic abundances, with a median of 2 microplastic particles per 500 g dry sediment and six polymer types identified.

Polymers

PE PET PP PS PVC

Study Type Environmental

Abundance and composition of beach litter and microplastics (20-5000 μm, excluding fibres) were assessed in spring and autumn 2018 at various beaches along the Baltic Sea coast of Schleswig-Holstein, Northern Germany. The beach litter survey followed the OSPAR guidelines, while microplastics were extracted from sediment samples using density separation and were then identified with Raman μ-spectroscopy. We observed seasonality in the abundance and composition, but not in the mass of beach litter. The median microplastic abundance was 2 particles per 500 g of dry sediment in spring as well as in autumn, while six different synthetic polymers (PE, PP, PS, PET, PVC, POM) were detected. We found no correlation between the abundances of beach litter and microplastics. Our data represent the first systematic co-assessment of macro- and micro beach litter along the Baltic Sea coast of Schleswig-Holstein.
