Abstract: A study was conducted to assess the level of heavy and trace metals in water and fish caught from Soan and Korang rivers located in the surrounding of Rawalpindi and Islamabad areas. Results indicates that the higher concentrations of metals like Cd, Cr, Cu Zn and Fe were present not only in river waters but also in muscles, livers and gills of various fish species surviving in these rivers. Therefore on basis of results obtained it is predicted that if present trend of metal pollution will continue then in future our drinking water will also get more than enough metals. The input concentrations of heavy and trace metals in the drinking water or in the food adversely effects on various organs of humans and animals.
