Twenty-seven coastal seawater samples were collected to assess seawater pollution and document the possible sources at Al-Khafji coastal area, Arabian Gulf, Saudi Arabia. Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Sr, Cd, Hg, and Pb were analyzed using inductively coupled plasma mass spectrometer (ICP-MS). The results revealed the following order of concentration: Sr > Ni > V > Cu > As > Zn > Al > Fe > Cr > Mn > Pb > Co > Cd > Hg. Most metals exhibited a fluctuated pattern within the studied sites without obvious trend, except Sr and Ni, which showed a fluctuated pattern with increasing trend southwards. The studied sites were classified into polluted, slightly polluted, and non-polluted ones based on HCA analyses. The higher levels of metals in the seawater of the polluted sites may be attributed to atmospheric input and oil spills from underwater pipelines, off offshore oil wells, loading and handling operations, oil terminals, and oil tanker incidents in the Arabian Gulf in general and many other anthropogenic sources in Al-Khafji area in particular such as desalination plant, landfilling due to new constructions, industrial sewage, and the Khafji Joint Operations (KJO).
采集了 27 个沿海海水样本，以评估阿拉伯湾沙特阿拉伯卡夫吉沿海地区的海水污染情况并记录可能的污染源。使用电感耦合等离子体质谱仪（ICP-MS）分析了 Al、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、As、Sr、Cd、Hg 和 Pb。结果表明，浓度顺序如下：Sr>Ni>V>Cu>As>Zn>Al>Fe>Cr>Mn>Pb>Co>Cd>Hg。除 Sr 和 Ni 外，大多数金属在研究地点的浓度呈波动模式，没有明显的趋势，而 Sr 和 Ni 的浓度呈波动模式，且呈向南递增的趋势。根据 HCA 分析，将研究地点分为污染、轻度污染和无污染三类。污染区海水金属含量较高，可能是由于大气输入以及水下管道、近海油井、装卸作业、油码头和阿拉伯湾油轮事故造成的石油泄漏所致，此外，在卡夫吉地区还有许多其他人为污染源，如海水淡化厂、由于新建筑造成的垃圾填埋、工业污水以及卡夫吉联合作业（KJO）。
