SUMMARY :The objectives of this paper were to illustrate the distribution and levels of sediment contamination by heavy metals in the Allahabad city, and to compare recent data with those collected during the early 2001. The metals as, Cd, Ni, Cu, Fe, Pb, Co, Ni and Zn were chosen because of their abundance and toxic effects in the environment of highly industrialized and urbanized areas. The pollutants, which do not remain in water column or solution, could be absorbed rapidly by particulate matters and thereby they also could escape any detection by water monitoring schemes (Meiggs, 1980). Some heavy metals like Cd, Cu, Fe, Ni and Pb were determined in water from four reaches of the river from Yamuna (river-km 1112) upstream from Sangam to Arail Ghat (riverkm 851) downstream from Allahabad.HOW TO CITE THIS ARTICLE : Naushad, Syed Suaib, Lall, Alok Milton and Charan, Amit Alexander (2014).

Pollution of water sources due to chemicals plays a primary role in the destruction of ecosystems but chemical analyses alone may not suffice to describe the adverse effects of the complex mixtures of chemicals present at contaminated sites. The potential utility of biomarkers for monitoring both environmental quality and the health of organisms inhabiting in the polluted ecosystems has received increasing attention during the last years. In the present investigation, the antioxidant profile of Clarias batrachus, a fresh water fish was determined by evaluation of antioxidant enzymes, SOD activity, catalase activity, glutathione peroxidase activity, glutathione-S-transferase activity, reduced glutathione, level of conjugated dienes, hydrogen peroxidase activity and malondialdehyde level. The studies showed that in fishes after exposure to phenolic compounds (treated group), there was a significant abnormal level of all the parameters as mentioned above at P<0.05 in comparison to normal (untreated group).
