Sažetak
Variations in the elemental composition of different carp (Cyprinus carpio) organs (liver, kidney, eggs, intestine, spleen and skin + muscle) from three Croatian fish farms were investigated. Sediments and water samples were also taken from each pond. All measurements were carried out by the source excited Energy Dispersive X-Ray Fluorescence method (EDXRF). Significant difference was found in the sediment and water composition among the three fish farms (p < 0.01). Compared to fish farm 1, concentrations of heavy metals in sediments and water from fish farm 2 were between 2 and 6 times higher and from fish farm 3 between 2 and 5 times higher. The following concentrations ranges (expressed as wet weight) were measured in different carp organs: Pb (0.11– 1.45 mg/kg) ; Cr (0.10– 3.72 mg/kg) ; Mn (1.70– 28.47 mg/kg) ; Fe (8.09– 117.21 mg/kg) ; Cu (0.41– 4.09 mg/kg) and Zn (4.61– 171.53 mg/kg). Significant difference was found in selected heavy metal concentrations of selected organs at each location as well as among the three locations (p < 0.05). Generally, carp from fish farm 2 had the highest concentration of the majority of elements (Pb, Cr, Mn, Fe Cu, Zn), while carp from fish farm 1 had the lowest concentration, demonstrating an impact of the geochemical environment on heavy metal concentrations in carps.
