The presence of microplastics (MPs) in the marine environment is a concerning topic due to the ecotoxicological effects and possible seafood contamination. Data is needed to evaluate human exposure and assess risks, in the context of a healthy and beneficial seafood consumption. While microplastic ingestion by wild fish has been reported since the early 70's, farmed fish are rarely investigated. Here, for the first time the presence of microplastics in fish cultivated in the coastal water of Tenerife (Canary Island, Spain) was evaluated. From 83 examined individuals, 65% displayed microplastics in their gastrointestinal tracts, with averages between 0.6 ± 0.8 (SD) and 2.7 ± 1.85 (SD) particles per fish. The total number of microplastics detected was 119. Fibres (81%) and fragments (12%) were the predominant shapes. FTIR analysis showed that fibres were mostly composed by Cellulose (55%) and Nylon (27%), whereas fragments by PE (25%) and PP (25%).
微塑料（MPs）在海洋环境中的存在是一个令人关注的问题，因为它们具有生态毒性效应，并可能导致海鲜污染。需要数据来评估人类暴露程度和风险，以实现健康和有益的海鲜消费。虽然早在 70 年代就有报道称野生鱼类会摄入微塑料，但养殖鱼类却很少被研究。在这里，首次评估了在西班牙特内里费岛（Canary Islands）沿海水域养殖的鱼类中微塑料的存在情况。在所检查的 83 个个体中，有 65%的个体在其胃肠道中发现了微塑料，平均每个鱼类中有 0.6±0.8（SD）和 2.7±1.85（SD）个颗粒。共检测到 119 个微塑料。纤维（81%）和碎片（12%）是主要形状。FTIR 分析表明，纤维主要由纤维素（55%）和尼龙（27%）组成，而碎片则由 PE（25%）和 PP（25%）组成。
