Heavy metals have a great ecological significance due to their toxicity and accumulative behavior. The geoaccumulation index (Igeo) in 10 stations in Al-Hawizeh Marsh, (i.e Al-Adaim (I & II), Um Al-Neaj (I & II), Um-Awarded, North Al-Soudah, South Al-Soudah, Al-Beda, Lissan Ejerdah and Majnoon) were calculated in this article. The sediment pollution was investigated by following the concentration of six heavy metals (As, Cd, Cr, Co, Cu and Pb). Inductively coupled plasma mass spectroscopy (ICPMS) was used for analysis. According to the geoaccumulation index (Igeo) the results of all the 10 stations were analyzed and discussed in detailed.
