Izmir Bay is one of the great natural bays of the Mediterranean. The surface sediment and fish samples were collected during 1997-2009. The sediment concentrations of inner bay showed significant enrichments during sampling periods. Outer and middle bays exhibited low levels of metal enrichments except the estuary of Gediz River. The concentrations were generally higher than the background levels from the Mediterranean and Aegean except Cd and Pb levels gradually decreased. Metal EF is used as an index to evaluate anthropogenic influences of metals in sediments. Maximum metal enrichment was found for Hg in the outer bay, while Pb indicated maximum enrichment in the middle-inner bays. Metal levels were evaluated in sediments in accordance with the numerical SQG of the USEPA. The levels of fish tissues were lower than the results reported from polluted areas of the Mediterranean. The highest BAFs were detected for Hg and Cd in fish.
伊兹密尔湾是地中海的一个大型天然海湾。1997 年至 2009 年期间采集了表层沉积物和鱼类样本。在采样期间，内湾的沉积物浓度显示出明显的富集。除了格迪兹河河口外，外湾和中湾的金属富集水平较低。除了 Cd 和 Pb 水平逐渐降低外，这些浓度普遍高于来自地中海和爱琴海的背景水平。EF 用于评估沉积物中金属的人为影响。在外湾，Hg 的金属富集最大，而在中内湾，Pb 则表明金属富集最大。根据美国环保署的数值 SQG 对沉积物中的金属水平进行了评估。鱼类组织中的金属水平低于来自地中海污染地区的报告结果。在鱼类中，Hg 和 Cd 的 BAFs 最高。
