Surface sediments in the fraction < 63 microm collected from eight stations along the north coastline of Izmit Bay, north-eastern Marmara Sea, Turkey, were analyzed for major (organic carbon, Al, Ba, Fe and Mg) and trace (As, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn) elements by using inductively coupled plasma atomic emission spectrometry (ICP-AES). Sediments heavily contaminated are evaluated by the Sediment Quality Guidelines (SQG) of US EPA. The results were compared with the marine sediment quality standards (SQS), as well as literature values reported to assess the pollution status of the sediments. The enrichment factors (EFs) were calculated to evaluate actual level of contamination for all the elements using the earth crust as reference matrix, based on elemental values by Mason which show a normal pattern near to unity. The analysis revealed two groups of elements: (i) Arsenic, Cd, Pb, and Zn are the most enriched elements; (ii) Barium, Co, Cr, Cu, Fe, Mg, Mo and Ni are at background levels. The results show that road traffic run-offs, paint industries and coal combustion are among the most significant sources.
从土耳其马尔马拉海东北部伊兹密特湾北海岸线的八个站点采集了粒径小于63微米的表层沉积物,采用电感耦合等离子体原子发射光谱法(ICP-AES)对其中的主要元素(有机碳、铝、钡、铁和镁)和微量元素(砷、镉、钴、铬、铜、钼、镍、铅和锌)进行了分析。利用美国环境保护局(US EPA)的沉积物质量指南(SQG)对重度污染的沉积物进行了评估。将结果与海洋沉积物质量标准(SQS)以及为评估沉积物污染状况而报告的文献值进行了比较。以地壳为参考基质,根据梅森给出的接近1的正常模式的元素值,计算了富集因子(EFs)以评估所有元素的实际污染水平。分析揭示了两组元素:(i)砷、镉、铅和锌是富集程度最高的元素;(ii)钡、钴、铬、铜、铁、镁、钼和镍处于背景水平。结果表明,道路交通径流、涂料行业和煤炭燃烧是最重要的污染源。
