Metal pollution in the marine coastal environment is an important topical issue. In this study, the water quality in five locations along the Alexandria coast (Eastern Harbor, El-Tabia pumping station, El Mex Bay, Sidi Bishir, and Abu Talat) was assessed by measuring physicochemical parameters from water samples. Depending on the morphological classification of macroalgae, the collected morphotypes were related to Ulva fasciata, Ulva compressa, Corallina officinalis, Corallina elongata, and Petrocladia capillaceae. Corallina officinalis and Corallina elongata demonstrated a high capacity for Cd, Pb, and Ni accumulation, and the highest values of Fe, Cu, and Mn were reported in Ulva fasciata and Ulva compressa. Two standard markers were applied, and results showed that the morphological classification matched the molecular data. Moreover, the analysis of algae can only reflect the accumulation of metals. The conclusion is that Ulva compressa and Corallina officinalis are potentially suitable indicators of localized short-term heavy metal pollution.
海洋沿岸环境中的金属污染是一个重要的热门话题。在本研究中，通过测量水样的理化参数，对亚历山大港沿岸五个地点（东港、埃尔塔比亚抽水站、埃尔梅克斯湾、西迪比希尔和阿布塔拉特）的水质进行了评估。根据大型海藻的形态分类，所收集的形态型与扁浒苔、肠浒苔、珊瑚藻、长珊瑚藻和毛细仙菜有关。珊瑚藻和长珊瑚藻对镉、铅和镍具有较高的积累能力，浒苔和肠浒苔中铁、铜和锰的含量最高。应用了两个标准标记，结果表明形态分类与分子数据相符。此外，藻类分析只能反映金属的积累情况。结论是，肠浒苔和珊瑚藻可能是局部短期重金属污染的合适指示生物。
