In this study, the aim was to study the concentrations of metals in the solungating and muscular tissues of the four species of fish living in the Axu river (Barbus capito, Cyprinus carpio, Salmo trutta macrostigma, Capoeta tinca) that were thrown into the sea on the coast of Giresun. Metal accumulations in the solvents of the examined species; kobalt: 0,08- 0,2, chromium: 0,18-3,61, baker: 6,10-33,8, iron: 54,6-671, manganese: 7,74-62,0, nickel: 0,95-4,34, bullet: 0,72-7,07 and zinc: 66,8-315, while muscle tissue; kobalt: <0,01-1,00, chromium: 0,36-2,57, baker: 7,92-40,4, iron: 46,0-469, manganese: 1,36-15,2, nickel: 0,66-3,29, bullet: 0,88-8,89 and zinc: 43,8-233 in mg kg-1 age weight. Differences between stations and metal levels in seasons have been statistically significant (p<0,05). In general, solving metal accumulations were found higher than the quantities in the muscles. The metallic accumulations in the nutritious muscle of the surveyed fish were compared to the temporary acceptable daily (PTDI) and weekly (PTWI) intake for human consumption. The results showed that when assessed in terms of human consumption, the concentrations of metals in the studies are below the limits recommended by the Food and Agriculture Organization (FAO), the World Health Organization (WHO) and the Environmental Protection Agency (EPA).
