In recent years, the accumulation of heavy metals in the environment mostly due to its adverse impact on human health and wildlife has become a main concern (Al-Yemni et al., 2011). Meanwhile, sediments are the main storing heavy metals accumulations and serve as tools for assessing the status of river pollution (Taghinia Hejabi et al., 2010). At the same time, to using geographic information systems and Geostatistic methods is desirable. Many studies have been conducted by researchers such as Mortazavi and Saberi nasab (2017) in Meiqan, and Islam et al. (2015) in the water and sediments of the Korotoa River in Bangladesh. The purpose of this study was to investigate the concentration of lead, zinc, copper and chrome metals in surface sediments of GharehSo River and zoning of sediments of the region with Potential Ecological Risk Index and Muller's Geo-accumulation Index.
