Various elements as possible cause of skeletal system deformities in natural populations of fish from the Karin sea, Croatia

In this study, because of the increased prevalence of skeletal system deformities in natural populations of fish from the Karin Sea in Croatia (i.e. in grass goby, black goby and sandsmelt), and in order to exclude essential and toxic metals as a possible cause of these changes, we determinate concentrations of Li, B, Na, Mg, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Sn, Sb, Ba, Hg, Pb, Al, Cs, U, Bi and Ti in sediment and liver of grass goby (Zosterisessor ophiocephalus) with clinically visible deformities. Sediment and grass goby with no visible deformities collected from the nearby Novigrad Sea were chosen as control group. Concentrations of selected elements were determined using ICP-MS method and are expressed as mgkg-1 wet weight. The results of this preliminary study suggest that other causes could be responsible for observed changes.
