Heavy metal contents and contamination degree of deposited sediments from runoff and industrial effluents in Shiraz city, Iran are investigated. Concentrations of the heavy metals display the following decreasing trend: Ni>Cr>Zn>Cu>Mo>Cd. The higher Enrichment factor values (EFs) for all heavy metals belong to drainage deposits collected from densely populated areas. Geo accumulation index (Igeo) results are in agreement with EF. Pearson correlation matrix as well as principal components and cluster analyses are applied on data to identify inter- relationships and sources of the heavy metals. Cd, Cu, Mo, Pb and Cu are positively correlated showing an anthropogenic origin. There is also a positive correlation between Ni, Cr and Mn probably indicating a geogenic source. Principal component analysis is in agreement with Pearson correlation matrix. Cluster analysis classifies the samples into two clusters.
