Abstract
The study investigates heavy metal (HM) contamination in coastal sediments of Jeddah along Red Sea coast, analyzing spatial distribution and sources. 24 samples underwent (ICP-AES) for Fe, Al, Mn, Ni, Pb, Zn, Cu, Cr, Co, Sr, V, and As. HM averages followed Fe ˃ Al ˃ Sr ˃ Mn ˃ Zn ˃ V ˃ Cu ˃ Ni ˃ Cr ˃ As ˃ Co ˃ Pb. Contamination indices revealed severe Sr enrichment, minor As and Co enrichment, and no enrichment for other HMs. Sediment quality guidelines suggest Ni, Cu, Zn, and As risks to benthic communities at some sites, while Cr and Pb pose minimal risk. Multivariate analysis indicates natural sources for Fe, Al, Mn, Ni, Zn, Cu, Cr, Co, and V, and anthropogenic sources for Sr, As, and Pb, linked to agriculture, industry, and urbanization. Increased Sr values may stem from seawater acidification impacting calcitic corals and molluscs.
本研究调查了吉达红海沿岸沉积物中的重金属(HM)污染情况,分析了其空间分布和来源。对 24 个样本进行了铁、铝、锰、镍、铅、锌、铜、铬、钴、锶、钒和砷的(ICP-AES)检测。HM 平均值如下:Fe ˃ Al ˃ Sr ˃ Mn ˃ Zn ˃ V ˃ Cu ˃ Ni ˃ Cr ˃ As ˃ Co ˃ Pb。污染指数显示,锶富集严重,砷和钴富集轻微,其他 HMs 没有富集。沉积物质量指标表明,镍、铜、锌和砷对某些地点的底栖生物群落有风险,而铬和铅的风险很小。多变量分析表明,Fe、Al、Mn、Ni、Zn、Cu、Cr、Co 和 V 具有自然来源,Sr、As 和 Pb 具有人为来源,与农业、工业和城市化有关。硒值的增加可能是由于海水酸化影响了钙质珊瑚和软体动物。
