Geochemical Assessment of Some Heavy Metal Levels in Neka River Sediments-Neka City, Iran

M.R. Kalantari and A.G. Ebadi    

Abstract: The Neka River watershed covers a large portion of Mazandaran province, Iran and is centrally important to both recreational and other activities in the region. In order to assess current water quality conditions distribution of three heavy metals were determined in river sediments at four sampling stations in the watershed. Cu, Cr and Fe concentrations were determined using flame atomic absorption spectrometry. Standard operating procedures for the analysis of metals were used. Metal concentrations in sediments ranged from 6.35 to 13.56 for Cu, 17.66 to 209.7 Cr and 1.5 to 23.4 for Fe mg g-1 dry weight sediment. The results showed higher concentrations of Cu, Cr and Fe in the test samples compared to that in the control.Significant difference in level of Cu, Cr and Fe was seen between test and control groups (p<0.05 for Cu and Fe ; p<0.001 for Cr). This study can be an alarm to researchers for more study about pollution of sediments in Mazandaran and finding proper methods for reducing and removing.
