Environmental Assessment of Water and Fish of the River Nile at Cairo

Agricultural and industry discharge water are considered the most dangerous water pollution sources to the River Nile at Greater Cairo. Consequently the chemical analysis of the water in the River Nile at selected stations as the determination of some heavy metals and pesticides have a great importance to people health. Therefore the aim of this work was to assess if the changes of the River Nile at Greater Cairo water and fish (Oreochromis niloticus Tilapia zillii and Clarias gariepinus). The selected stations were before El-Hawamdyia El-Hawamdyia after El-Hawamdyia Shoubra El-Khima El-Warrak and El-Kanater El-Khyria. The study included water quality heavy metals (water sediment and fish) inorganic anions (water sediment and fish) pesticides distribution (water sediment and fish) and water microbiology during 2014-2015. Pesticide residues (water sediment and fish) showed that chlorpyrifos had most detected amount followed by dicofol. Microbiological studies showed that there were some contaminations distributed at all sides with coliform Escherichia coli pathogenic strains and Faecal streptococci. Hoosier Riverwatch Water Quality Index also were done.
