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.

调查来自沙特阿拉伯塔伊夫市场的金枪鱼、鲑鱼和沙丁鱼罐头中的微塑料和潜在有毒元素污染

微塑料 (MPs) 已记录在不同的食品和饮料中，它们可能会因摄入而影响人类健康。此外，海产品受到国会议员的污染，使食品供应和利用的支柱面临风险。本研究调查了来自塔伊夫省市场的商业罐头鱼中的 MPs 和有毒元素污染。在本研究中使用了来自不同制造商国家的七种不同的鱼罐头品牌，并从塔伊夫市场购买。用 10% 的 KOH 消化组织样品；然后，通过傅里叶变换红外光谱分析干式过滤器以检测 MP。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。在食用组织中检测到不同的 MPs，例如被尼龙污染的金枪鱼罐头、1,2-聚丁二烯、和乙烯乙烯醇。沙丁鱼含有乙烯乙烯醇和聚（硬脂酸乙烯酯），但鲑鱼没有任何 MP。所选样品中的不同元素以 Al > Se > Zn 的递减顺序以及痕量的 As 和 Sb 的顺序存在。罐头鱼被 MPs 和潜在的有毒元素污染。这种污染可能是对长期接触潜在健康风险的警告。因此，建议将微塑料、中塑料甚至纳米塑料纳入食品安全管理体系测试指南。罐头鱼被 MPs 和潜在的有毒元素污染。这种污染可能是对长期接触潜在健康风险的警告。因此，建议将微塑料、中塑料甚至纳米塑料纳入食品安全管理体系测试指南。罐头鱼被 MPs 和潜在的有毒元素污染。这种污染可能是对长期接触潜在健康风险的警告。因此，建议将微塑料、中塑料甚至纳米塑料纳入食品安全管理体系测试指南。
