The environmental pollution indicators and multivariate statistical analysis were used to evaluate the potential ecological risk and the contamination of Fe, Mn, Zn, Ni, Pb, Cu, Cd, and Co in surface sediments of the Egyptian Red Sea coast. The results revealed that the studied area suffers from high contamination of certain metals such as the Hurghada area (Pb, Cd, Zn, Ni, and Cu), Quseir City area (Cd, Co, Pb, and Ni), and Safaga and Marsa Alam areas (Cd and Pb). Enrichment factor and principal components analysis reported that the pollution sources of Fe, Mn, and Co are related to natural weathering process while Cu, Zn, Ni, and Pb are related to anthropogenic sources as landfill, plastic rubbish, fishing boats, phosphate operations, and tourist activities. Moreover, Co and Cd metals can come from both of natural and anthropogenic sources. The average concentrations of Cd, Cu, Zn, Pb, Ni, and Co in sediments of the Egyptian Red Sea coast are higher than those in the coasts of the Red Sea (Saudi Arabia), Mediterranean Sea (Egypt and Libya), Bengal bay (India), and the Caspian Sea (Russia). However, the studied metal content is lower than the sediment quality guideline values except for Cd.
采用环境污染指标和多元统计分析方法，评估了埃及红海沿岸表层沉积物中铁、锰、锌、镍、铅、铜、镉和钴的潜在生态风险和污染状况。结果表明，某些金属（如赫尔格达地区的铅、镉、锌、镍和铜，库赛尔市地区的镉、钴、铅和镍，以及萨法加和马萨阿拉姆地区的镉和铅）在研究区域受到了高度污染。富集因子和主成分分析表明，铁、锰和钴的污染来源与自然风化过程有关，而铜、锌、镍和铅则与人为来源（垃圾填埋场、塑料垃圾、渔船、磷矿作业和旅游活动）有关。此外，钴和镉金属可能来自自然和人为来源。埃及红海沿岸沉积物中镉、铜、锌、铅、镍和钴的平均浓度高于红海（沙特阿拉伯）、地中海（埃及和利比亚）、孟加拉湾（印度）和里海（俄罗斯）沿岸的沉积物。然而，除了镉之外，研究中金属的含量均低于沉积物质量指导值。
