In this study, we examined seawater from Izmir Bay, Turkey for its trace element content. Three stations were chosen to carry out our mission. The sample collection process took place between November 2019 and May 2020. We focused on pH levels, dissolved oxygen, total dissolved solids, salinity, conductivity values, and trace elements (Ag, Al, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Ni, Pb, Sr, and Zn) concentrations. Trace element analysis was done using an ICP-OES. Trace element concentrations were as follows: Ag (0.4 mg/l), Al (0.47 mg/l), Cu (0.82 mg/l), Li (0.81 mg/l), Pb (0.065 mg/l), and Sr (8.06 mg/l). Meanwhile, Ba, Cd, Co, Cr, Fe, Mn, and Ni levels were below the measurable limits. Our results are generally high when compared with the literature. Industrial pollution sources (cement, metallurgy, iron and steel industries, electric arc furnaces (EAF-Steel), coal combustion residuals (CCRs), and petrol refineries) all cause marine pollution because they leak trace elements into the sea, which consequently accumulate over time.

Bu çalışmada İzmir Körfezi’nden alınan deniz suyundaki iz element içeriği incelenmiştir. Üç istasyon amaca uygun olarak seçilmiştir. Örnek toplama işlemi Kasım 2019 ve Mayıs 2020 arasında gerçekleştirilmiştir. pH, çözünmüş oksijen, toplam çözünmüş madde miktarı, tuzluluk, iletkenlik seviyelerine ve iz element (Ag, Al, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Ni, Pb, Sr, and Zn) konsantrasyonlarına odaklanılmıştır. İz element analizi ICP-OES kullanılarak yapılmıştır. İz elemnt konsantrasyonları sırasıyla şu şekilde bulunmuştur: Ag (0.4 mg/l), Al (0.47 mg/l), Cu (0.82 mg/l), Li (0.81 mg/l), Pb (0.065 mg/l) ve Sr (8.06 mg/l). Ayrıca Ba, Cd, Co, Cr, Fe, Mn ve Ni seviyeleri ölçülebilir limitlerin altında kalmıştır. Sonuçlarımız genel olarak literatürle kıyaslandığında yüksektir. Endüstriyel kirlilik kaynakları (çimento, metalürji, demir - çelik endüstrileri, elektrik ark ocakları (EAF-Çelik), kömür yakma artıkları (CCR) ve petrol rafinerileri) eser elementleri denize sızdırdıkları ve biriktirdikleri için sonuç olarak zamanla deniz kirliliğine sebep olmaktadır.
