The Golden Horn Estuary and Bosphorus Strait are two major marine environments of metropolitan Istanbul which have been exposed to intensive industrial discharges for more than 50 years. In the present study, concentrations of cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn) were measured in mussel tissue and sediment samples by using inductively coupled plasma-atomic emission spectroscopy to assess the current status of metal pollution in the Golden Horn and Bosphorus Strait. Ranges of Cd, Cr, Cu, Pb and Zn concentrations in soft parts of the mussels were BDL-2.59; BDL-7.35; 3.96-20.90; BDL-10.0; and 124.8-293.2 μg g(-1) dry weight (dw), respectively, while the ranges of Cd, Cr, Cu, Pb and Zn in <63 μm sediment fractions were BDL, 19.5-300.3, 16.9-724.7, 10.5-260.9, and 39.3-793.1 μg g(-1) dw, respectively. Ranges of Cd, Cr, Cu, Pb and Zn in >63 μm sediment fractions were BDL, 4.73-52.81, 3.45-481.87, 3.13-174.67 and 10.7-241.2 μg g(-1) dw, respectively. Trace metal concentrations found in sediment of the Golden Horn were 5-10 times higher than average literature values obtained in Mediterranean marine environment, whereas those of the Bosphorus Strait were consistent with or slightly higher than average literature values.
金角湾和博斯普鲁斯海峡是伊斯坦布尔大都市的两个主要海洋环境，它们已经受到超过 50 年的密集工业排放的影响。在本研究中，使用电感耦合等离子体原子发射光谱法测量贻贝组织和沉积物样品中的镉（Cd）、铬（Cr）、铜（Cu）、铅（Pb）和锌（Zn）浓度，以评估金角湾和博斯普鲁斯海峡的金属污染现状。贻贝软体组织中 Cd、Cr、Cu、Pb 和 Zn 的浓度范围分别为 BDL-2.59；BDL-7.35；3.96-20.90；BDL-10.0；124.8-293.2μg g(-1) 干重（dw），而<63μm 沉积物部分的 Cd、Cr、Cu、Pb 和 Zn 浓度范围分别为 BDL、19.5-300.3、16.9-724.7、10.5-260.9 和 39.3-793.1μg g(-1) dw，>63μm 沉积物部分的 Cd、Cr、Cu、Pb 和 Zn 浓度范围分别为 BDL、4.73-52.81、3.45-481.87、3.13-174.67 和 10.7-241.2μg g(-1) dw。金角湾沉积物中的痕量金属浓度比地中海海洋环境中获得的平均文献值高 5-10 倍，而博斯普鲁斯海峡的浓度则与平均文献值一致或略高。
