Microplastic pollution and its potential impacts on humans become a global concern. This study is the first study examining the microplastic ingestion in the commercially important species Oncorhynchus mykiss Rainbow trout (Walbaum, 1792), Sparus aurata Gilthead seabream Linnaeus, 1758, and Dicentrarchus labrax European seabass (Linnaeus, 1758) from Turkey. The occurrence frequency of microplastic (MP)in the gastrointestinal tract (GIT) was varied between 50 and 63 %. The highest MP abundance in the GIT was estimated in Rainbow trout (1.2 MPs individual) followed by European seabass (0.95 MPs individual) and Gilthead seabream (0.8 MPs individual). Most of the extracted microplastic particles were black (61 %) and blue (27 %) in color and fiber (80 %) in shape. Major identified polymers were polyethylene (25 %), polyester (20 %), polyamide (10 %). Since fish consumption is an important route for MPs, results light up the danger potential for humans. This study will fill the information gap in Turkey and show the necessity of protection measures in aquaculture industry.
微塑料污染及其对人类的潜在影响成为全球关注的焦点。本研究首次检测了土耳其商业重要鱼类虹鳟（Oncorhynchus mykiss Rainbow trout）、金头鲷（Sparus aurata Gilthead seabream）和欧洲鲈鱼（Dicentrarchus labrax European seabass）消化道中微塑料的摄入情况。微塑料在消化道中的出现频率在 50%到 63%之间有所不同。虹鳟消化道中微塑料的丰度最高（1.2 个个体中有 1 个微塑料），其次是欧洲鲈鱼（0.95 个个体中有 1 个微塑料）和金头鲷（0.8 个个体中有 1 个微塑料）。提取的微塑料颗粒多数为黑色（61%）和蓝色（27%），形状为纤维状（80%）。主要鉴定出的聚合物为聚乙烯（25%）、聚酯（20%）和聚酰胺（10%）。由于鱼类消费是微塑料的重要途径，因此研究结果揭示了其对人类的潜在危险。本研究将填补土耳其在这方面的信息空白，并显示水产养殖行业采取保护措施的必要性。
