Abstract
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.
