Assessment of water contamination, specially from anthropogenic contributions, is a global challenge due to its hazardous effects on marine organisms and human health. The present work aimed to document the state of heavy metal (HM) contamination and identify its potential sources in surface seawater along Ras Abu Ali Island, Arabian Gulf. Thirty-four seawater samples were collected and pollution indices, and multivariate statistical analyses were applied. The average concentration of HMS (μg/L) took the following descending order: Zn (11.44) > As (3.96) > Cu (3.77) > Ni (3.49) > Se (1.53) > Hg (0.65) > Co (0.27) > Pb (0.15) > Cd (0.08). The shallow southern part of the study area recorded the higher HM levels in comparison with the northern part faced to the open sea. The average values of Cu and Zn were greater than those reported from seawater in several coastal area of the Red Sea, Gulf of Aqaba, and Arabian Gulf. Levels of the heavy metal pollution index (HPI) indicated that 79.41% of the studied seawater samples fell under medium pollution and 20.59% fell under high pollution. However, all seawater samples are categorized under low contamination based on the degree of contamination (C_d). Multivariate analysis indicated anthropogenic sources for Pb, Hg, and Se, and mixed natural and anthropogenic sources for the remaining HMs.

由于水污染对海洋生物和人类健康的有害影响，评估水污染，特别是人为贡献，是一项全球性挑战。目前的工作旨在记录重金属 (HM) 污染的状况，并确定其在阿拉伯湾拉斯阿布阿里岛沿岸地表海水中的潜在来源。采集了 34 个海水样品和污染指数，并进行了多元统计分析。HMS的平均浓度（μg/L）依次为：Zn（11.44）>As（3.96）>Cu（3.77）>Ni（3.49）>Se（1.53）>Hg（0.65）>Co（0.27） > 铅 (0.15) > 镉 (0.08)。与面向公海的北部相比，研究区南部浅水区的 HM 水平较高。在红海、亚喀巴湾和阿拉伯湾的几个沿海地区，Cu 和 Zn 的平均值高于海水报告的平均值。重金属污染指数（HPI）水平表明，79.41%的研究海水样品属于中度污染，20.59%属于高污染。然而，所有海水样本都根据污染程度归类为低污染（丙_）。多变量分析表明 Pb、Hg 和 Se 的人为来源，以及剩余 HM 的混合自然和人为来源。
