Abstract

In this research, the SHEFA-RUD RIVER SEDIMENTS have been chemically analyzed to determine elemental matrix, HEAVY METALS concentrations and POLLUTION intensity. Though comparison of geochemical results with the world's standards have been a common practice since 1971 but the research results show that use of mean of the metals concentrations of the earth's crust and world SEDIMENTS are not suitable means to estimate the POLLUTION load in the study area. HEAVY METALS concentrations of SHEFA-RUD RIVER bed SEDIMENTS are under control by the geology of study area and as a matter of fact, limestone units have a greater significant role than the other units. As limestone contains lesser concentrations of HEAVY METALS, it is evident that the obtained concentrations are much lower than various world average sediment metal concentrations. Besides, natural organic materials have been effective in elemental absorption and formation of organic metal bond. In continuation of present research, Al, Ca, and LOI were used as the indices of lithogenous, biogenic and organic sources, respectively to find out the sources of Mn, Fe, Ni, Cu, Zn, Pb and Co. Though Fe and Mn have direct link with lithogenous index but we propose the same source for other studied metals. It is believed that organics and biogenic materials are land derived. Thus cluster analysis is indicative of lithogenous source for HEAVY METALS in the study area, and fortunately no evidence of SHEFA-RUD RIVER bed sediment elemental POLLUTION has been observed. "Muller" geochemical Index (Igeo) is a proof to this fact, and the index output calculations demonstrate unpolluted class for Mn-Pb-Ni-Cu-Zn-Fe in the SEDIMENTS.
