This study assesses microplastic ingestion in Boops boops at different geographical areas in the Mediterranean Sea. A total of 884 fish were caught at 20 coastal sites in Spain, France, Italy and Greece and analyzed using a common methodological protocol. Microplastics were found in 46.8% of the sampled fish, with an average number of items per individual of 1.17 ± 0.07. Filaments were the predominant shape type, while polyethylene and polypropylene were indicated by FTIR as the most common polymer types of ingested microplastics. The frequency of occurrence, as well as the abundance and proportion of types (size, shape, color and polymer) of ingested microplastics, varied among geographical areas. The spatial heterogeneity of the abundance of ingested microplastics was mainly related to the degree of coastal anthropogenic pressure at the sampling sites. Our findings further support the suitability of B. boops as bioindicator of microplastic pollution in the Mediterranean Sea.
本研究评估了在地中海不同地理区域的拟庸鲽体内的微塑料摄入情况。在西班牙、法国、意大利和希腊的 20 个沿海地点共捕获了 884 条鱼，并使用通用的方法学方案进行了分析。在 46.8%的采样鱼中发现了微塑料，平均每个个体的微塑料数量为 1.17±0.07 个。纤维是主要的形状类型，而傅里叶变换红外光谱（FTIR）表明，摄入的微塑料中最常见的聚合物类型为聚乙烯和聚丙烯。摄入的微塑料的出现频率、丰度和类型（大小、形状、颜色和聚合物）比例在地理区域之间有所不同。摄入的微塑料丰度的空间异质性主要与采样点的沿海人为压力程度有关。我们的研究结果进一步支持拟庸鲽作为地中海微塑料污染生物指示剂的适用性。
