The present study was conducted to investigate the trace metal contents (Al, As, Ba, Cd, Co, Cr, Cu, Mo, Mn, Pb, Ni, Sr, V, U and Th) of water samples, which were collected from 10 different sites along the river Kura in Azerbaijan Republic. Agilent 7700x Series ICP-MS was used for measurements. The mean concentration of studied metals in the water, followed the decreasing order of Sr > Ba > Al > Fe >Mo > V > As > Cu > U > Ni > Cr > Co > Pb. The concentration of Cadmium and Thorium in all samples were less than 0.02 μg/L and 0.01 μg/L respectively. The measured metals content in water samples for all sites has been found to be less than the limit of recommended by the World Health Organization. The analysis of results showed strong concentration correlation (R: 0.8-1) between groups of elements: 1) Al-Cu-Fe-Ni, 2) Cu-Ni-Co, 3) Al-Pb-Fe, 4) Mo-U- Sr and 5) Ba-Cr at p-value < 0.01 level and may indicate same source. A strong negative correlation exists between Fe and Ba R=-0.65 and is an indication of distinct sources for the metals in the river.
