Microplastics in seawater and fish from the Baltic Sea were analyzed. The significant contribution of the study is due to extensive collection of fish and surface water samples from corresponding fishing zones. Microplastics were detected in 100 % of seawater and 61 % of fish samples. The abundances of microplastics were 19,984 ± 8858 items/m (seawater) and 3.3 items/fish in the fish organs. The average dimension was 1.08 ± 1.19 mm (seawater), and 0.77 ± 0.84 mm (fish). In 106 out of 178 specimens (61 %), MPs were found in the gills (46 %), digestive tract (38 %), or liver (16 %). Fiber was the most dominant shape found in seawater (91.7 %) and fish (68.3 %), while the dominant color of items was blue. Items were mostly composed of polyethylene (21 %), polypropylene (20 %), cellophane (16 %), polyamide (9 %), and polyacrylate (8 %).
对波罗的海海水和鱼类中的微塑料进行了分析。该研究的重要贡献在于从相应捕捞区域广泛收集了鱼类和地表水样本。在100%的海水样本和61%的鱼类样本中检测到了微塑料。海水中微塑料的丰度为19,984±8858个/立方米，鱼体内微塑料丰度为3.3个/鱼。平均尺寸方面，海水样本中为1.08±1.19毫米，鱼类样本中为0.77±0.84毫米。在178个样本中的106个（61%）中，微塑料存在于鳃（46%）、消化道（38%）或肝脏（16%）中。纤维是海水中（91.7%）和鱼类中（68.3%）最主要的形状，而微塑料的主要颜色为蓝色。微塑料大多由聚乙烯（21%）、聚丙烯（20%）、玻璃纸（16%）、聚酰胺（9%）和聚丙烯酸酯（8%）组成。
