本研究评估了在红海沙特阿拉伯海岸沿着采样的四种不同栖息地的26种商业和非商业鱼类胃肠道内容物中存在的微塑料垃圾。共有178人接受了微塑料检查。共发现26个微塑料碎片，其中16个为薄膜（61.5%），10个为鱼线（38.5%）。FTIR分析表明，最丰富的聚合物是聚丙烯和聚乙烯。石斑鱼（Epinealus spp.）在贾赞的采样记录了最高的微塑料摄入量。这种鱼是底栖的，以底栖无脊椎动物为食。虽然物种之间微塑料摄入量的差异在统计学上并不显著，但当比较栖息地之间微塑料颗粒的摄入水平时，观察到了显著的变化。微塑料颗粒丰度较高可能与鱼类的栖息地以及海底附近存在微塑料碎片有关。这项研究的结果首次证明，微塑料污染对红海鱼类、其食物网和人类消费者构成了新的威胁。
This study assesses the presence of microplastic litter in the contents of the gastrointestinal tract of 26 commercial and non-commercial fish species from four difference habitats sampled along the Saudi Arabian coast of the Red Sea. A total of 178 individual were examined for microplastics. In total, 26 microplastic fragments were found. Of these, 16 being films (61.5%) and 10 being fishing thread (38.5%). FTIR analysis revealed that the most abundant polymers were polypropylene and polyethylene. The grouper (Epinephelus spp.) sampled at Jazan registered the highest number of ingested microplastics. This fish species is benthic and feeds on benthic invertebrates. Although differences in the abundance of microplastic ingestion among species were not statistically significant, a significant change was observed when the level of ingestion of microplastics particles was compared among the habitats. The higher abundance of microplastics particles may be related to the habitats of fish and the presence of microplastics debris near the seabed. The results of this study represent a first evidence that microplastic pollution represents an emerging threat to Red Sea fishes, their food web and human consumers.
