This is a first attempt to assess the levels of trace elements, PAHs, and TPHs in six elasmobranch species (Carcharhinus dussumieri, C. sorrah, Chiloscyllium arabicum, Gymnura poecilura, Sphyrna lewini, S. mokarran) from the Arabian Gulf. The chemical analysis showed that the concentrations of contaminants differed significantly between liver and muscle samples with both pelagic and benthic species and all families. For all species, contaminant concentrations were significantly higher in the liver than in the muscle. While muscle contaminant concentrations differed significantly with respect to species' lifestyles and families, those of liver showed no significant differences between pelagic and benthic species, neither between the four families nor between the six species. None of the analysed contaminants exceeded the internationally recognized standards in all studied species. These results enrich the knowledge on the bioaccumulation of contaminants in elasmobranchs and allow to assess the environmental status of the Arabian Gulf.

这是首次尝试评估来自阿拉伯湾的六种软骨鱼类（ Carcharhinus dussumieri、C. sorrah、Chiloscyllium arabicum、Gymnura poecilura、Sphyrna lewini、S. mokarran ）的微量元素、PAH 和 TPH 水平。化学分析表明，中上层和底栖物种以及所有科的肝脏和肌肉样本中污染物的浓度存在显着差异。对于所有物种，肝脏中的污染物浓度明显高于肌肉中的污染物浓度。虽然肌肉污染物浓度因物种的生活方式和科而异，但肝脏污染物浓度在中上层和底栖物种之间、四个科之间或六个物种之间没有显着差异。所有研究物种的分析污染物均未超过国际公认的标准。这些结果丰富了软骨鱼污染物生物累积的知识，并有助于评估阿拉伯湾的环境状况。
