    The present study was conducted to assess the accumulation of some metals (Fe, Cd, Cu, Pb, Mn, Mg, Ca and Zn) in the River Nile water and sediment, at four sites (Gezyrat Al- Warrak (site I), Manial Sheeha (site II), Al- Hawamdia (site III) and Helwan (site IV), at Great Cairo, as well as in the exoskeleton, hepatopancreas , muscles and gills of the crayfish Procambarus clarkii, collected from the same sites). The results obtained show that the different concentrations of the metals in the Nile water were in the descending order Mg>Zn>Fe>Cu>Mn>Pb>Cd, at all studied sites. Fe and Zn concentrations were higher than the permissible limits, while the remaining metals were within the allowable levels. Whereas, the concentrations of metals in the sediment showed different patterns, according to their abundance in water. The abundance of these metals in the sediment was in .. Read More»
