Abstract :In this study, the accumulation concentration of copper (Cu), iron (Fe), nickel (Ni), zinc (Zn), and arsenic (As) in water, sediment, and gill tissues of brown trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss), and shabut (Tor grypus) fish in Atatürk Dam Lake were evaluated by ICP-MS. Regarding Fe and Ni accumulation, the difference between rainbow trout and other species was found to be statistically significant (p<0.05). In terms of Cu and Zn accumulation, it was determined that the difference between Brown trout and other species was statistically significant, and the concentration of As accumulation was less and statistically significant (p<0.05). In shabut fish, it was determined that Fe accumulation in terms of weight was statistically significant (p<0.05) and As and Cu accumulated more than other fish gills (p<0.05). In water samples, it was determined that the concentration of Cu and Fe (1. and 3. regions) were above the reference values according to the reference values of the surface water quality regulation of the Republic of Turkey, and the concentration of Fe was above the reference limits set by the World Health Organization (2022). In sediment samples, Cu and Fe concentration were found to be above the serious and toxic effect reference values. As a result, it was observed that metals accumulated in gill samples of different fish species living in Atatürk Dam at different rates depending on the species, and the concentration of Fe and Cu were high in sediment and Fe in water samples.
