Rapid industrialization has led to an extraordinary increase in environmental pollution in Arak, Iran. This study classified the distribution of iron (Fe), manganese (Mn), lead (Pb) and cadmium (Cd) in sediments and soils of Mighan Playa (Iran) and analysed the pollution sources using geostatistical methods. Samples were taken from 250 points and the data analysed by means of SPSS, GS+ and ArcGIS. The soils were moderate to considerable polluted with Pb and high to very high polluted with Cd. The comparison of the maps of EF for Pb and Cd with the maps of their total contents indicated they have two different distributions in the region. Lead was enriched near the pollution sources. However, Cd accumulated at the centre of Mighan Playa apart from the pollution sources, meaning Cd was highly mobile in the studied wet and salty soils
