The major risk of microplastics in marine environments is the bioaccumulation in marine organisms. Plastic ingestion by marine organisms has been investigated and recently more attention has been given to microplastics in seafood. However, it is seldom reported the occurrence of microplastics in marine commercial dried fish products available for human consumption. Here, we report the occurrence of microplastics in 14different marine dried fish products from seven Asian countries. Microplastics were observed in most dried fish, with fibers representing ~80% of the total-microplastics. The major plastic polymers, identified using Micro-Raman spectroscopy, included polyethylene (35%), polyethylene terephthalate (26%), polystyrene (18%), polyvinyl chloride (12%), and polypropylene (9%). The highest count, in either per individual (1.92 ± 0.12) or per gram of dried fish (0.56 ± 0.03), were found in Etrumeus micropus from Japan. Marine dried fish, which are typically eaten whole, may contribute to the ingestion of microplastics by humans, posing potential health risks especially in Asian countries. Further studies are needed to identify the occurrence of smaller sized microplastics and nanoplastics and their potential health impacts.

海洋环境中微塑料的主要风险是海洋生物体内的生物累积。已经调查了海洋生物摄入塑料的情况，最近人们对海产品中的微塑料给予了更多关注。然而，很少有人报道在可供人类食用的海洋商业干鱼产品中出现微塑料。在这里，我们报告了来自 7 个亚洲国家的 14 种不同海洋干鱼产品中微塑料的存在情况。在大多数干鱼中都观察到微塑料，其中纤维约占微塑料总量的 80%。使用显微拉曼光谱鉴定的主要塑料聚合物包括聚乙烯 (35%)、聚对苯二甲酸乙二醇酯 (26%)、聚苯乙烯 (18%)、聚氯乙烯 (12%) 和聚丙烯 (9%)。每个人的最高计数（1.92 ± 0.来自日本的Etrumeus micropus 。通常整条食用的海洋干鱼可能会导致人类摄入微塑料，从而构成潜在的健康风险，尤其是在亚洲国家。需要进一步的研究来确定较小尺寸的微塑料和纳米塑料的发生及其潜在的健康影响。
