Sažetak
The fish meat is valuable foodstuff of animal source. Environment pollution, also, water pollution is dangerous for the health and life of organisms which live in it. Water, among others, can be polluted with heavy metals, so fish from this water can be used as the monitoring organisms of environment pollutions with heavy metals. The concentrations of heavy metals higher from allowed the fish as animal source can make dangerous and harmful for human health. Concentrations of heavy metals (Pb, Cr, Mn, Fe, Cu and Zn) were measured in different organs (kidney, liver, intestine, spleen and skin + muscle) of grass carp (Ctenopharyngodon idella) and bighead carp (Hypophthalmichthys molitrix), and in mud and water from fish farm from the continental part Republic of Croatia. All measurements were carried out by the fluorescence roentgen spectroscopy that uses energy dispersion (Energy Dispersive X-Ray Fluorescence Method (EDXRF). Significant difference was found in the mud and water composition (p<0, 05), and those between fish tissue for lead (p<0, 01) and manganese (p<0, 05). It shows that grass carp is the first fish for determinations of environment pollutions for heavy metals. Determinate values do not over cross maximal allowed concentrations of heavy metals in edible fish parts (skin + muscle).
