对采集自伊朗波斯湾沿岸海域的78个海洋沉积物样品进行了16种元素和有机碳含量的测定。采集了9个垂直于海岸线的断面。采用电感耦合等离子体质谱(ICPMS)和电感耦合等离子体原子发射光谱仪(ICPAES)分别测定了砷、钡、镉、钴、铜、锰、镍、铅、锌(痕量金属)和钙、铁、镁、钠、磷、S、硅(主要金属元素)等16种元素。在本研究中，沉积物中的元素浓度没有超过沉积物质量标准，也没有造成环境问题，但镍的含量超过了ERM。Spearman相关矩阵表明，除砷、镉、钡和硅外，其余元素与铁均显著相关(P<；0.01)。具有ISQG值的元素的相对污染因子(RCF)和用Fe计算的富集系数(EF)表明，除镍外，没有自然或人为来源的金属富集化。高Ef值表明，波斯湾沉积物中的镍可能来源于人为来源。
The concentrations of sixteen elements and organic carbon were determined in 78 marine sediment samples collected from the Iranian coastal waters of the Persian Gulf. Nine transects perpendicular to the coastline were sampled. Sixteen elements, including As, Ba, Cd, Co, Cu, Mn, Ni, Pb, Zn (trace metals) and Ca, Fe, Mg, Na, P, S, Si (major metals), were determined by Inductively Coupled Plasma Mass Spectrometry (ICP MS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), respectively. In this study, the element concentrations in sediments have not exceeded the sediment quality guidelines and pose no environmental concerns with the exception of Ni, which is over than ERM. The spearman correlation matrix demonstrated that all elements except for arsenic, cadmium, barium and silicon, were significantly (P<0.01) correlated with iron. The Relative Contaminated Factor (RCF) for elements which had ISQG values and Enrichment Factors (EF) using Fe demonstrated that there was no metal enrichment by natural or anthropogenic sources except for Ni. High EF level for Ni demonstrated that nickel level in sediments of the Persian Gulf could have originated from anthropogenic sources.
