For the first time, the qualitative and quantitative characteristics of marine debris ingested by six hawksbill (Eretmochelys imbricata) and seven olive ridley (Lepidochelys olivacea) sea turtles from the Gulf of Oman coast of the United Arab Emirates were investigated. The numeric and gravimetric proportions of ingested marine debris obtained from the esophagus, stomach and intestines were quantified following categories of presumed sources, Marine Strategy Framework Directive (MSFD), rigidity, color and plastic polymer types. Marine debris was observed in 28.6% of olive ridley (x̅: 2.00 items; 4.83 g) and 83.3% of hawksbill specimens (x̅: 6.00 ± 2.32 items; 0.32 ± 0.24 g). Overall, the results of this preliminary study suggest that hawksbill sea turtles were ingesting marine debris at higher frequencies and that plastics were observed to be the most predominant debris ingested. However, non-plastic rubbish, particularly metallic fishing gear (fish hooks and fish traps), were observed to present lethal hazards for both species.
首次对来自阿拉伯联合酋长国阿曼湾沿海的 6 只玳瑁（Eretmochelys imbricata）和 7 只绿海龟（Lepidochelys olivacea）海龟摄入的海洋碎片的定性和定量特征进行了研究。通过假定来源、海洋战略框架指令（MSFD）、刚性、颜色和塑料聚合物类型对食道、胃和肠中摄入的海洋碎片的数量和重量比例进行了量化。在绿海龟（x̅：2.00 个项目；4.83 克）和玳瑁标本的 28.6%（x̅：6.00±2.32 个项目；0.32±0.24 克）中观察到了海洋碎片。总的来说，这项初步研究的结果表明，玳瑁海龟摄入海洋碎片的频率更高，而塑料是最主要的摄入碎片。然而，非塑料垃圾，特别是金属渔具（鱼钩和鱼陷阱），对这两个物种都构成了致命的危害。
