| Abstract | ||||
| In the current study, a comparison was conducted between different water drains (Bahr El-Baqar, El-Rahawy and Um El-Resh) and the River Nile water at El-Kanater sector in terms of muscle pollution. In addition, the effect of pollution on heavy metals concentrations in the liver and gills of fish samples from different locations was studied. All heavy metal concentrations examined for the Nile tilapia harvested from El-Rahawy and Um El-Resh were lower than the permissible limits, except for lead which showed slightly higher values. The levels of all studied metals such as Fe, Zn, Cu and Pb were above the permitted levels for human consumption in Bahr El-Baqar drain. Consequently, fish consumption from Bahr El-Baqar drain should not be permitted. While the Nile tilapia sampled from the River Nile is safe for human consumption. Higher pollution levels were recorded for Bahr El-Baqar drain, with regard to four heavy metals including Fe, Zn, Cu and Pb. Consequently, a strict monitoring program should be applied in order to sustain the safety of the Nile tilapia for consumers. | ||||
