—Heavy metal contamination of the environmental aria has attracted a great deal of world-wide attention due to their non-biodegradable nature, long-biological half-lives for elimination from the body, their accumulation in the food chain will have a significant effect on human health in the long term.
The objectives of this study were (1) determine the physical characteristics (sediment size) of surface sediments in Shafaroud, Iran, (2) determine the relation between physical characteristics (grain size) with heavy metals pollution by using cluster analysis and multivariate statistical techniques. Distribution of total concentration of heavy metals are different in fractioned sediments. Metals that have more abundance in particles less than 38 μm (clay and silt) like Cu, Zn and Mn originated from anthropogenic source from sea water that attracted to fine minerals. Other metals like Cr that have more abundance in gravel and sand particles (particles grate than 63 μm) related to natural sources. Also, these metals are found in river’s placers.
