Considering that microplastics are widespread in the marine environment, in this study we evaluated the presence, identify distribution, abundance, shape type, and color of microplastics in surface sediment along the Montenegrin coast, on the Adriatic Sea. These preliminary results provide the first published record of microplastics found in the surface sediment of this area and highlight the importance of microplastics as a component of marine debris. We documented the presence of microplastics at all sampling locations. The identification of polymer types was performed using Fourier-transform infrared (FTIR) spectroscopy, whereby the presence of three polymer types became evident: polypropylene (54.5%), polyethylene (9.7%), and acrylate copolymer (2.0%). Another 22.2% of particles were unidentified polymers, and the remaining 11.5% were non-synthetic materials. The most common shape type of microplastics was filaments (55.5%), followed by granules (26.3%), fragments (14.9%), and films (3.3%). The dominant colors of microplastics followed the order: blue > yellow > red > clear > black > green > blue-white > white. The average abundance of microplastics in all sampling locations was 609 pieces of microplastic/kg of dry sediment. Compared with other studies, the surface sediment of the Montenegrin coast is moderately to highly polluted with microplastics, depending on the examined location.

亚得里亚海黑山海岸地表沉积物中的微塑料：类型、发生率和分布

考虑到微塑料在海洋环境中广泛存在，在本研究中，我们评估了亚得里亚海黑山沿岸表层沉积物中微塑料的存在、确定分布、丰度、形状类型和颜色。这些初步结果提供了在该地区表层沉积物中发现的微塑料的首次公开记录，并突出了微塑料作为海洋垃圾组成部分的重要性。我们记录了所有采样地点都存在微塑料。聚合物类型的鉴定是使用傅里叶变换红外 (FTIR) 光谱进行的，其中三种聚合物类型的存在变得明显：聚丙烯 (54.5%)、聚乙烯 (9.7%) 和丙烯酸酯共聚物 (2.0%)。另外 22.2% 的颗粒是不明聚合物，其余 11%。5% 是非合成材料。最常见的微塑料形状类型是细丝 (55.5%)，其次是颗粒 (26.3%)、碎片 (14.9%) 和薄膜 (3.3%)。微塑料的主色顺序为：蓝>黄>红>透明>黑>绿>蓝白>白。所有采样地点的微塑料平均丰度为 609 件微塑料/千克干沉积物。与其他研究相比，黑山海岸的表层沉积物受到微塑料的中度至高度污染，具体取决于所检查的位置。蓝白色 > 白色。所有采样地点的微塑料平均丰度为 609 件微塑料/千克干沉积物。与其他研究相比，黑山海岸的表层沉积物受到微塑料的中度至高度污染，具体取决于所检查的位置。蓝白色 > 白色。所有采样地点的微塑料平均丰度为 609 件微塑料/千克干沉积物。与其他研究相比，黑山海岸的表层沉积物受到微塑料的中度至高度污染，具体取决于所检查的位置。
