Metal contamination in fish is a concern worldwide, including in the Arabian/Persian Gulf region. This review summarizes the findings from 55 papers about metal concentrations in Gulf fish. Metal concentrations in muscle tissue were screened against the most recent maximum allowable levels (MALs) for fish in international commerce. We identified metals, fish species, and locations where concentrations exceeded the MALs. For some metals, recent MALs have been set to lower concentrations as more toxicological data have become available. Mean fish tissue concentrations exceeded the MAL in 13% (arsenic), 76% (cadmium), 56% (lead), and 10% (mercury) of species means. We identified 13 fish species with the potential to serve as bioindicators of metal contamination for use in four Gulf habitats: pelagic, benthopelagic, demersal, and coral reefs. Recommendations are provided for a regional approach to improve consistency of sampling, data analysis and reporting of metal concentrations in Gulf fish.
鱼类金属污染是一个全球性的问题，包括在阿拉伯/波斯湾地区。本综述总结了 55 篇关于海湾鱼类金属浓度的论文的研究结果。对肌肉组织中的金属浓度进行了筛选，以检测其是否超过了国际商业鱼类的最新最大允许水平 (MAL)。我们确定了浓度超过 MAL 的金属、鱼类物种和地点。对于一些金属，随着更多毒理学数据的出现，最近的 MAL 已被设定为更低的浓度。在 13%（砷）、76%（镉）、56%（铅）和 10%（汞）的物种平均值中，鱼类组织中的平均浓度超过了 MAL。我们确定了 13 种鱼类，它们有可能作为海湾四种生境（远洋、底栖远洋、底栖和珊瑚礁）中金属污染的生物指标。我们建议采取区域方法，以提高海湾鱼类金属浓度采样、数据分析和报告的一致性。
