The aim of this study was to analyze nine heavy and trace elements (Zn, Fe, Al, As, Cu, Sr, B, Cd and Ba) of the three tissues (muscle, liver and gills) in sterlet (Acipenser ruthenus), black sea shad (Alosa immaculata) and barbel (Barbus barbus). All three species were sampled on the Danube (1173, 1319 and 863 rkm) in Serbia. The obtained concentations of heavy metals and trace elements were used for obtaining an overview of the presence of the abovementioned elements in a descending order and calculate the value of MPI (Pollution Metal index), which represents the total quantity of heavy metals and trace elements per tissue and species. In all the analyzed specimens iron (Fe) and zinc (Zn) were dominant, followed by strontium (Sr) and aluminum (Al), and the other trace elements and heavy metals. The least represented metals were barium (Ba) and cadmium (Cd). MPI values were the highest in liver, followed by gills and muscle of all species; with the exception of barbel, which had extremely high MPI values in the gills.
