Total metal contents are different in the geological composition of the riverbed.
The ranges of the varied metal composition found in the riverbed are as follows
The degree of metal enrichment was compared with the standard shale concentration and shows exceptionally high values for Cr, Ni, Cu, Zn, Pb and Cd in the urban centres. In the total heavy metal concentration, anthropogenic input contains 70% Cr, 74% Cu, 59% Zn, 46% Pb, 90% Cd in Delhi and 61% Cr, 23% Ni, 71% Cu, 72% Zn, 63% Pb, 94% Cd in Agra.
A noteworthy relationship was observed between rising Cr, Ni, Zn, and Cu concentrations with increasing total sediment carbon and total sediment sulfur content. The Müller's geoaccumulation index mentioned that the quality of the river sediments could be regarded as being moderately polluted to very highly polluted with Cr, Ni, Cu, Zn, Pb and Cd in the particular urban centres like Delhi and Agra. The present sediment analysis, therefore, plays an important role in environmental actions for the Yamuna River and the planning of these city centres.
