Abstract: The study focuses on the partitioning of chromium, nickel, copper and lead among the components of the river Yamuna ecosystem (water, sediments, macrophytes and fish). The water is used for various purposes like irrigation, industrial, domestic and drinking. Almost zero dissolved oxygen and unacceptable levels of lead and phosphate pose a serious threat to the human and aquatic life.- The concentration of the metals in the sediments is noticeably higher than that present at the reference site and the enrichment ni factors with respect to it vary from 0.60%-82.9% (Cr), 1.40%-90.5% (Ni), 1.00%-85.3% (Cu) and 3.80%-86.6% (Pb). The metal contents in the macrophyte (Eichhomia crassipes) and the fish (Oreochromis niloticus) are reasonably high and generally increase in the summers. The fish is not recommended for human consumption as it'contains Cr, Cu and Pb above the permissible limits prescribed by FAO. One-way ANOVA indicates significant spatial variations in various parameters of water and sediments. The correlation analysis suggests a common source of some of the metals. Principal component analysis demonstrates that the domestic and industrial waste and coal fired thermal power plants contribute to the buildup of metal concentrations. On the basis of the findings some remedial measures are suggested.
