The existence of microplastics (MPs) in canned fish (tuna and mackerel) samples was investigated and their composition, possible sources and potential intake were assessed. Light and fluorescence microscopy were used for the quantification of potential MPs. Furthermore, micro-Raman microscopy, and scanning electron microscopy coupled with an energy dispersive X-ray were used to identify the polymer types and composition of MPs. The results showed that 80% of samples had at least one plastic particle and fibers were the most abundant shapes of MPs. Moreover, polyethylene terephthalate (32.8%) was the most common polymer type in canned fish samples. The fish, food additives, and contact materials during the cleaning and canning process are possible sources of MPs. Human intake estimation of MPs showed the possibility of plastics absorption by humans who consume canned fish several times/week. Hence, the results of this study showed the importance of MPs' guidelines for food safety and hygiene.
研究了罐头鱼（金枪鱼和鲭鱼）样品中微塑料（MPs）的存在，并评估了它们的组成、可能的来源和潜在摄入量。使用光学显微镜和荧光显微镜对潜在 MPs 的含量进行了定量分析。此外，还使用微拉曼显微镜和扫描电子显微镜结合能谱仪来识别 MPs 的聚合物类型和组成。结果表明，80%的样品中至少有一种塑料颗粒，纤维是 MPs 中最常见的形状。此外，聚对苯二甲酸乙二醇酯（32.8%）是罐头鱼样品中最常见的聚合物类型。鱼类、食品添加剂和在清洁和罐装过程中接触的材料可能是 MPs 的来源。每周食用几次罐头鱼的人可能会摄入 MPs，对人类摄入 MPs 的估计表明了这种可能性。因此，这项研究的结果表明了 MPs 对食品安全和卫生的指导方针的重要性。
