Determining the potential bioavailability of heavy metals, evaluating according to adaptedregulations is essential to efficiently conserve our coastal and estuarine waters. In this study, it isaimed to determine the industrial pollution and various other pollution sources that the Black SeaBasin is exposed to by using DGT (Diffusive Gradients in Thin Films) method and grab (manuel)sampling method in water and sediment and to evaluate the existing pollution according to qualitystandards. In Samsun, seasonal samples were collected from five different sampling stations,namely Akkiraz Stream, Hıdırellez Stream, Organized Industrial Zone (OIZ) Channel, ŞabanoğluStream and Selyeri Stream, which are selected from Tekkeköy region where industry is intensivelyactive. In order to determine the heavy metal content in both water and sediment samples, the DGTmethod was chosen for passive sampling and the grab sampling method was used for activesampling, and the efficiency of the methods was evaluated. According to the results of the study,the heavy metal concentration in grab sampling for water samples in descending order Al> Fe> Zn>Pb> Ni> Cu; In the samples taken with DGT, they are listed as Al> Fe> Zn> Cu> Ni> Pb. Therewere significant relationships between the total metal concentrations of sediment (Csed) and water(Csu) in grab sampling and metal concentrations sediment (Csed-DGT) and water (Csu-DGT)measured by DGT. It was found that the sensitivity and performance of sampling with DGT was 2-10 times higher compared to grab sampling. The high resolution in situ DGT technique for theassessment and management of the potential release risk of heavy metals at the water-sedimentinterface is a complementary method that contributes to the standard grab sampling method.
