Microplastics (MPs) have been documented in different foodstuffs and beverages, that could affect human health due to their ingestion. Furthermore, seafood contamination with MPs puts pillars of food availability and utilization at risk. The present study investigates MPs and toxic elements pollution in commercially canned fishes from Taif governorate markets. Seven different canned fishes' brands were used in the present study from different manufacturer countries and purchased from Taif markets. Tissue samples were digested by 10% of KOH; then, dry filters were analyzed by Fourier-transform infrared spectroscopy to detect MPs. Filtrates were used to detect any potentially toxic elements by inductively coupled plasma. Different MPs were detected in edible tissue, such as canned Tuna contaminated with nylon, 1,2-polybutadiene, and ethylene vinyl alcohol. Sardines contain ethylene vinyl alcohol and poly(vinyl stearate), but Salmon does not have any MPs. Different elements were present in the selected samples in the decreasing order of Al > Se > Zn and traces of As and Sb. Canned fishes were contaminated with MPs and potentially toxic elements. This contamination could be a warning of the potential health risks with the long-term exposure. Therefore, it is recommended to include micro-, meso-, and even nanoplastics in the guidelines of testing food safety management systems.
微塑料（MPs）已在不同的食品和饮料中被记录下来，由于其被摄入，可能会影响人类健康。此外，海产品被微塑料污染使粮食供应和利用的支柱面临风险。本研究调查了塔伊夫省市场上商业罐装鱼类中的微塑料和有毒元素污染情况。本研究使用了来自不同生产国、从塔伊夫市场购买的七个不同品牌的罐装鱼类。组织样本用10%的氢氧化钾消化；然后，通过傅里叶变换红外光谱对干燥的滤膜进行分析以检测微塑料。滤液用于通过电感耦合等离子体检测任何潜在的有毒元素。在可食用组织中检测到了不同的微塑料，如被尼龙、1,2 - 聚丁二烯和乙烯 - 乙烯醇污染的罐装金枪鱼。沙丁鱼含有乙烯 - 乙烯醇和聚（乙烯硬脂酸酯），但三文鱼中没有任何微塑料。所选样本中不同元素的含量顺序为铝＞硒＞锌，还有痕量的砷和锑。罐装鱼类被微塑料和潜在的有毒元素污染。这种污染可能是长期接触潜在健康风险的一个警示。因此，建议在食品安全管理系统检测指南中纳入微塑料、中塑料甚至纳米塑料。
