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.
在 2018 年春季和秋季，对德国北部石勒苏益格-荷尔斯泰因州波罗的海沿岸的各个海滩进行了海滩垃圾和微塑料（20-5000μm，不包括纤维）的丰度和组成评估。海滩垃圾调查遵循了 OSPAR 指南，而微塑料则使用密度分离从沉积物样本中提取，然后使用拉曼微光谱法进行鉴定。我们观察到了丰度和组成的季节性变化，但海滩垃圾的质量没有季节性变化。春季和秋季，每 500 克干沉积物中微塑料的中位数含量分别为 2 个颗粒，同时检测到了六种不同的合成聚合物（PE、PP、PS、PET、PVC、POM）。我们没有发现海滩垃圾和微塑料丰度之间存在相关性。我们的数据代表了对石勒苏益格-荷尔斯泰因州波罗的海沿岸首次进行的宏观和微观海滩垃圾的系统综合评估。
