In this study, cellular biomarkers and heavy metal concentration in the Mytilus galloprovincialis L. (Mediterranean mussels) collected from eight sites of Izmir Bay (Turkey) were determined to reveal water pollution for the first time in these stations. Results show that heavy metals (As, Cu, Hg, Zn, Cd, Sn, Pb) have been specified in mussels' tissues collected from all stations. According to GST, SOD, CAT activities, and TBARS contents, mussels in the outer bay have exposed more oxidative stress than the ones in the inner bay. Digestive gland tissues of them were showed more inhibition at AChE levels than gills. Also, abnormal nucleus rates and micronucleus frequencies (MN) were found to be higher in the inner bay than in the outer bay. This study showed that heavy metal pollution in different levels is an environmental issue on the Izmir Bay. Especially the coastal regions of the bay have been extremely affected by anthropogenic effects due to growing population.
本研究旨在首次揭示伊兹密尔湾（土耳其）八个站点的水质污染情况，检测了贻贝（Mediterranean mussels）中细胞生物标志物和重金属浓度。结果表明，在所采集贻贝组织中均检出重金属（As、Cu、Hg、Zn、Cd、Sn、Pb）。根据 GST、SOD、CAT 活性和 TBARS 含量，外湾贻贝受到的氧化应激比内湾贻贝更严重。与鳃组织相比，其消化腺组织中 AChE 水平受到的抑制更为明显。此外，内湾的异常核率和微核频率（MN）高于外湾。本研究表明，不同程度的重金属污染是伊兹密尔湾面临的一个环境问题。特别是由于人口增长，该湾的沿海地区受到了人类活动的严重影响。
