A comparison of total metal concentrations in the water and sediment with the shale standard is generally taken as a quick and practical method of tracing heavy metals enrichment. The average shale values along with the metal concentrations reported by other workers on some of the major rivers of the world. In most of the cases the average total heavy metal (Cr, Cu, Fe, Mn, Ni and Zn) concentrations determined in Yamuna river sediments was found to be lower than the corresponding shale values except Cd and Pb. The cadmium concentration in the Yamuna river sediments was found to be more than 6 times higher (1.83 µg/g) than that of shale (0.30 µg/g), while lead concentration was 1.5 times higher (30.47 µg/g) than that of shale (20.0 µg/g). Overall the heavy metal concentration in the Yamuna river sediment is in good agreement with the shale standard. We have reported higher concentration of Cr, Cu, Fe, Mn, Ni and Zn in the bed sediment of the river Ganga, as compared to the results of present study whereas the Cd and Pb concentrations observed in the present study is higher than Ganga river sediments, also reported higher concentrations of Cd, Cr, Cu, Fe, Mn, Ni and Zn in Cauvery river system. When we compared our result with the Neckar River, the concentrations of metals in the bed sediment of river Yamuna were found lower than those of the Neckar river except Cd. Lead and Zn concentrations were found high in our study than Ganga river. Lead concentration in Yamuna river sediments was found higher than Guadairariver. A comparison of the present study result with the other rivers reveals that the average concentration of Cd and Pb are high in the Yamuna river sediments.
