Abstract

The present study provides the first comprehensive assessment of the distribution of heavy metals (Al, Fe, Mn, Co, Ba, Zn, Cr, Ni, As, Pb, Cd) in surface seawater of Al Hoceima Bay, Mediterranean Sea, Morocco, over an annual cycle. Water samples were collected in autumn 2022, winter, spring, and summer 2023 from fifteen sectors covering the entire bay. The analysis involved descriptive analysis, correlation matrices, PCA, and Cluster analysis. Concentrations of Pb and Cd were below detection limits, while Cr and Zn concentrations were below saltwater aquatic life preservation standards. However, As and Ni concentrations reached 49.55 μg/L and 12.71 μg/L respectively during autumn 2022 and summer 2023, exceeding international standards. The HPI indices, calculated using As, Cr, Ni, and Zn concentrations, indicated poor seawater quality during winter (HPI = 69.52) and spring (HPI = 75.08), and totally inadequate quality with likely adverse health effects during autumn (HPI = 114.64) and summer (HPI = 116.79). The study recommends continuous monitoring and integrated management to preserve the bay's biodiversity and ensure future sustainability.

本研究首次全面评估了摩洛哥地中海胡塞马湾表层海水中重金属（Al、Fe、Mn、Co、Ba、Zn、Cr、Ni、As、Pb、Cd）的年周期分布情况。2022 年秋季、冬季、春季和 2023 年夏季，从覆盖整个海湾的 15 个区域采集了水样。分析包括描述性分析、相关矩阵、PCA 和聚类分析。铅和镉的浓度低于检测限，铬和锌的浓度低于海水水生生物保护标准。然而，在 2022 年秋季和 2023 年夏季，砷和镍的浓度分别达到 49.55 μg/L 和 12.71 μg/L，超过了国际标准。利用砷、铬、镍和锌浓度计算得出的 HPI 指数表明，冬季（HPI = 69.52）和春季（HPI = 75.08）海水质量较差，而秋季（HPI = 114.64）和夏季（HPI = 116.79）海水质量完全不合格，可能对健康产生不利影响。研究建议持续监测和综合管理，以保护海湾的生物多样性，确保未来的可持续发展。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
