The aim of this study was to determine the levels of Cd, Co, Cr, Fe, Mn, Mn, Pb, Ni, Zn and hepaticmetallothionein (MT) in muscle, liver, kidney and gills of Capoeta trutta and Capoeta umbla caught from theMurat River. The length and weight of the fish were measured. The physical and chemical properties of the riverwater were measured and compared with the tolerable limits of Turkish Standards Institute (TSE). The tissues tobe analysed for heavy metals were prepared for the analyses using the wet incineration method in a closed system.The heavy metal content of the samples was measured by inductively coupled plasma optical emissionspectroscopy (ICP-OES). Differences in heavy metal accumulation of Capoeta trutta and Capoeta umbla indifferent tissues and different metal species were determined. The levels of Cr, Mn, Ni and Fe in the muscletissues of Capoeta trutta were higher than the limits recommended for fish by the Turkish Food Codex (TGK),the Food and Agriculture Organization (FAO) and the World Health Organisation (WHO). Muscle Cr, Mn, Niand Fe levels of Capoeta umbla were higher than the tolerable levels recommended by FAO and WHO. Heavymetals cannot be metabolised in tissues. They tend to accumulate. It has been observed that this accumulationvaries in muscle, liver, kidney and gills according to organ structure, metabolic activity and defence mechanismsagainst toxic substances. MT, an indicator of tissue metal accumulation, was found to differ between Capoetatrutta and Capoeta umbla liver tissues.
