The Mediterranean Sea is one of the most polluted seas in terms of marine debris. To analyze the ingestion of anthropogenic particles in two areas, 197 gastrointestinal tracts from four fish species - Trachurus mediterraneus, Sardina pilchardus, Engraulis encrasicolus and Boops boops - were studied. 127 anthropogenic particles were identified in the gastrointestinal tract of 28% of the samples using visual sorting methods. Individuals from the peninsular coast showed higher ingestion occurrence (36%) than those from the Balearic Islands (12%). Significant differences in the ingestion of anthropogenic particles were found between species with Trachurus mediterraneus identified as the most affected species (43% of the individuals with mean values of 1.13 ± 0.16 particles/individual), and Engraulis encrasicolus, the least affected (2.56% and 0.03 ± 0.16 particles/individual). Moreover, the proportion of ingestion amongst species was similar in both areas, highlighting the importance of studying the same species at different locations as marine debris bioindicators.
地中海是海洋废弃物污染最严重的海域之一。为了分析两个区域中人为颗粒的摄入情况，对来自四种鱼类（地中海鲱鱼、沙丁鱼、欧洲无须鳕和拟沙丁鱼）的 197 个胃肠道进行了研究。使用目视分拣方法在 28%的样本的胃肠道中鉴定出 127 个人为颗粒。半岛海岸的个体比巴利阿里群岛的个体（12%）表现出更高的摄入发生率（36%）。不同物种之间在摄入人为颗粒方面存在显著差异，其中地中海鲱鱼被确定为受影响最严重的物种（43%的个体平均摄入 1.13±0.16 个颗粒/个体），而欧洲无须鳕受影响最小（2.56%和 0.03±0.16 个颗粒/个体）。此外，两个区域中物种的摄入比例相似，这突出了作为海洋废弃物生物标志物在不同地点研究相同物种的重要性。
