Abstract: Zayanderood is the only permanent river in central iran and the main feeding source for regional aquifers that plays a key role in providing esfahan province with drinking water. Because of the importance of this river in terms of its various uses and the fact that it receives waste materials from heavy industries, In order to study the motion changes of the potentially poisonous elements of lead and zinc and their effective factors in zayanderood river, Eleven surface sediment samples were taken along the beds of the river course (up stream to down stream). Total metal concentrations were obtained after acid digestion and then analysis was carried out by ICP-AES. The results from the analysis of fine grain sediments (particles smaller than 63 µ) indicate a high concentration of lead and zinc in several sampling stations. The concentrations of zinc & lead have been 494.3 ppm and 40.45 ppm respectively. The separation of human factors from natural ones was done by!
comparing lead & zinc concentrations at" Zaman khan" bridge station (as the reference sample) with those of the other sampling stations by obtaining the enrichment coefficient. Taking into account the results and coefficients, obtained and comparing those with widely used international standards, it seems the two elements of lead and zinc have not natural sources in some of the stations.
