Abstract

This study was conducted to determine some HEAVY METALS (Fe, Mg, Cr, Ni) of SURFACE SEDIMENT in thesouthern CASPIAN SEA during two seasons (Summer and Winter) in 2014-2015.36 SURFACE SEDIMENTssamples (with triplicate) were collected at two stations (Tonekabon and Bandar Amirabad). Allsamples were analyzed using sequential extraction to indicate natural and anthropogenic sources. Theresults indicated that the percentage of non-resistance fraction in Tonekabon area were measured3.5, 45.0, 22.1 and 6.0 for Fe, Mg, Cr, Ni, respectively and in Amirabad area were 23.0, 2.6, 1.8 and 4.0, respectively. On the other hand, the percentage of resistance fraction values were obtained 96.5, 55.0, 77.9 and 94.0 in Tonekabon, and 77.0, 97.4, 98.2, and 96.0 in Amirabad region. The chemicalspeciation of Fe, Mg, Cr, Ni in most sampling stations were in the order of residual>oxidisableorganic>acid-reducible>exchangeable. The order of total concentration, non-resistance andresistance fraction were observed Fe>Mn>Ni>Cr, Mn>Fe>Ni>Cr and Fe>Mn>Ni>Cr, respectively. Asa conclusion, results of total concentration, resistnace and non-resistance of Fe, Mn, Ni and Cr werelower than standard and earth shell (Igeo) in this area. This is shown that SURFACE SEDIMENTs of this areawere not polluted with these HEAVY METALS and bioavaiable fraction provides little indication ofpotential interactions with the biotic components present in this environment.
