Zarivar Lake, located west of Marivan city, Kurdistan Province, is an important freshwater lake in Iran. This study determined the concentration, origin, and distribution of heavy metals (Ni, Co, Mn, Ti, and V) in Zarivar Lake bed sediments. The sediment samples were collected from 31 stations. Cluster and Pearson correlation analyses were used to evaluate the relation between metals and physicochemical parameters of the samples. Ni, V, Co, and Ti were strongly correlated with each other and were negatively correlated with Mn. A distribution map of the metals was drawn using the ARC GIS 9.2 software. Results showed that metal concentrations were low and sediments were not contaminated by Ni, Co, Mn, Ti, and V. The presence of metals in bed sediments is controlled by local geological units. The mean variation in metal concentrations was Ti > Mn > V > Ni > Co. The results of the geoaccumulation index (Igeo) showed that the samples were practically not polluted by these five metals. The source of Mn appears to be different from the other studied metals. Enrichment factors for these five elements were lower than pollution limits, which indicated low enrichment. The pollution index showed moderately polluted sediments with regards to Ni, Ti, Co, and V, and unpolluted sediments with regards to Mn, which showed the human impact on the concentration of these metals.
