ABSTRACT the primary lithogenic source of heavy metals. Heavy metals discharged into the aquatic bodies In this research paper physico-chemical analysis of persist for long time and accumulate along the food sediments in the downstream of Kathajodi river, Odisha were studied. The parameters studied were chain. Metals present in the environment in minute pH, EC dSm-1, O.C., N, P, K and the heavy metal i.e. quantities become part of various food chains Cd, Ni, Cu, Zn, Pb, Fe, Mn. pH of sediments in all sites through biomagnifications and their concentration of river bed of Kathajodi are acidic and the dominance increases to such a level that may prove to be toxic of heavy metals follows a decreasing order of to both humans and other living organisms.

The present study shows the Sediments are ecologically important components heavy metal in sediments in the river Kathajodi may of the aquatic habitat and are also a reservoir of be highly harmful to the flora and fauna. the contaminants, which play a significant role in maintaining the trophic status of any water body Key Words Heavy metal, physico-chemical, (Golterman, 1967; Singh et al., 1997). Depending sediments. upon the limnological condition, the sediment can act both as a source, as well as sink for the nutrients Environment is a complex natural resource and other elements (Thoronton et al., 1975). Study system that has originated from millenniums of of sediments plays an important role as they have evolutionary process during which all ecosystems a long residence time. River sediments, therefore, and forms of life have developed. Twentieth century are important sources for the assessment of man- particularly has witnessed man’s dominance over made contamination in rivers. Singh et al., 2002 environment. In recent years, rapid economic and also reported that highly polluted sediments are industrial growth intensified environmental adversely affecting the ecological functioning of pollution. One of the consequences of the escalating rivers due to heavy metal mobilization from urban industrial activity is the growing accumulation of areas in to biosphere. surface sediment samples recalcitrant elements in natural ecosystems; from river bed from river bank were collected particularly the accumulation of heavy metals in during post monsoon period in the month of aquatic ecosystem. It has become a problem of December, 2011 and laboratory analysis followed great concern throughout the world as these metals during January and February, 2012. River Kathajodi are indestructible and have toxic effect on living in the Cuttack urban area is significant distributaries organisms when they exceeds critical of river . The exponential growth of concentration limit (Macfarlane and Burchet, 2000). Cuttack on the left side of Kathajodi river has led Increase in population, urbanization, industrialisation to severe water pollution in Kathojodi river. Water and agricultural practices have further aggravated coming from upper stream of river Mahanadi also the situation (Giguere et al., 2004). Heavy metals carries sediments containing heavy metals due to are of particular concern due to their environmental its geogenic as well as anthropogenic origin. persistence, biogeochemical recycling and Thus the heavy metal pollutants accumulated ecological risk.
