Wild fish (Cyprinus carpio, Mugil cephalus, Platichthys flesus) from an estuary of the NE Atlantic coast were investigated for plastic contamination (N = 128). From the 1289 particles recovered from fish samples, 883 were plastics. Among these, 84% were fibres and 97% were microplastics. Thirty-six polymers were identified. The number of microplastics (mean ± SD) per individual fish (MP/fish) was 8 ± 6 in C. carpio, 10 ± 9 in M. cephalus and 2 ± 2 in P. flesus. The means of MP/fish per body site were 6 ± 7 in gastrointestinal tract, 0.5 ± 1.1 in gills, 0.3 ± 0.7 in liver and 0.6 ± 1.2 in muscle samples. A few large fibres in liver (≤ 4841 μm) and muscle (≤ 5810 μm) samples were found. The results evidence the existence of high fish contamination by microplastics and reinforce the need of further research on plastic pollution in estuaries.
从北大西洋东北海岸的一个河口采集野生鱼类（鲤鱼、鲻鱼、欧鲽）样本，调查其塑料污染情况（N=128）。从鱼类样本中回收的 1289 个颗粒中，有 883 个是塑料。其中，84%是纤维，97%是微塑料。鉴定出 36 种聚合物。每只鱼（MP/fish）体内的微塑料数量（平均值±标准差）为鲤鱼 8±6 个，鲻鱼 10±9 个，欧鲽 2±2 个。每个身体部位的微塑料平均值±标准差分别为：胃肠道 6±7 个，鳃 0.5±1.1 个，肝脏 0.3±0.7 个，肌肉样本 0.6±1.2 个。在肝脏（≤4841μm）和肌肉（≤5810μm）样本中发现了少量较大纤维。研究结果表明，鱼类受到微塑料的高度污染，需要进一步研究河口的塑料污染问题。
