The concentrations of trace metals (Cu, Zn, Mn, Ni, and Fe) from suspended particulate matter (SPM) and biota in Izmir Bay (Eastern Aegean Sea) were studied in order to evaluate the environmental impact of the anthropogenic metals before building of Wastewater Treatment Plant. SPM samples were collected in wet and dry periods from Izmir Bay. Metal concentrations in SPM (Cu, 0.36-2.19; Mn, 0.07-11.3; Ni, 0.43-7.81; Zn, 7.33-269; Fe, 1.00-266 μg dm(-3)) were comparable to those reported for other moderately polluted bays. Maximum metal concentrations in SPM were observed during summer season. SPM metal concentrations displayed a clear spatial trend with values increasing with proximity to urban centers. Cu and Zn concentrations in SPM were especially high in the inner bay. SPM were found to be contaminated by Zn. The vertical profile of Mn, Zn, and Ni concentrations in SPM had a maximal value at the upper layer and decreased to minimal value at the bottom layer of the inner bay in summer, in contrast to the observed pattern of Fe and Cu. Maximum Cu concentrations were obtained in Penaeus kerathurus. Also, maximum Zn and Fe concentrations were found in Mytilus galloprovincialis. Relatively high Cu levels were found in Sardina pilcardus and Mullus barbatus than other fish species. Besides, Cu levels were lower in Diplodus annularis and Merluccius merluccius. Finally, metal levels in biota tissues were lower than the limits of European Dietary Standards and Guidelines.
为了评估在建造废水处理厂之前人为金属对环境的影响，研究了伊兹密尔湾（爱琴海东部）悬浮颗粒物（SPM）和生物体内痕量金属（Cu、Zn、Mn、Ni 和 Fe）的浓度。在伊兹密尔湾的湿季和干季采集了 SPM 样本。SPM 中的金属浓度（Cu，0.36-2.19；Mn，0.07-11.3；Ni，0.43-7.81；Zn，7.33-269；Fe，1.00-266μg dm(-3)) 与其他中度污染海湾报道的浓度相当。SPM 中的金属浓度在夏季达到最大值。SPM 中的金属浓度呈现出明显的空间趋势，随着与城市中心的接近，浓度值增加。Cu 和 Zn 在 SPM 中的浓度在内湾特别高。SPM 受到 Zn 的污染。Mn、Zn 和 Ni 在 SPM 中的垂直分布在夏季在上层达到最大值，在内湾的底层达到最小值，与 Fe 和 Cu 的观察模式相反。在 Penaeus kerathurus 中获得了最大的 Cu 浓度。此外，在 Mytilus galloprovincialis 中发现了最大的 Zn 和 Fe 浓度。与其他鱼类相比，Sardina pilcardus 和 Mullus barbatus 中的 Cu 水平相对较高。此外，Diplodus annularis 和 Merluccius merluccius 中的 Cu 水平较低。最后，生物组织中的金属水平低于欧洲饮食标准和准则的限制。
