Abstract:
Heavy metals are the most important form of pollution of
the aquatic environment because they are toxic and
bioaccumulate in the body of aquatic organisms of which fish
is the most valuable. Inaddition to protein and vitamins, fish
(which forms part of the human diet) is a rich source of
minerals which play essential role in human health .Polluted
.fish is then a dangerous source of toxic metals to humans
The present work examined the concentration levels of
Pb, Cd, Ni, Cu, Mn and Fe in water and inOreocromisniloticus
fish of Jebel Aulia dam Lake. A correlation between the
concentration of each of the metal contaminants in fish and
its body size (weight and length) was also investigated
Samples of water and fish (which were decomposed by dry
ashing) were collected from Jebel Aulia Dam Lake, and their
metals content (Pb, Cd, Ni, Mn, Cu and Fe) were determined
by inductively coupled plasma-emission spectroscopy (ICP(
