“…The Nile River is Egypt's principal source of freshwater, and its flow rate is dependent on the amount of water stored in Nasser Lake to meet the country's annual water needs ( Othman et al, 2021). The high dam at Aswan and a series of seven barrages between Aswan and the Mediterranean Sea totally control the Nile River (Al-Afify & Abdel-Satar, 2020).…”

“…Heavy metals make up most of these contaminants, which eventually end up in bottom sediments (Abou El-Anwar et al, 2021). Pollution discharges, particularly heavy metals and nutrient salts, have severe influences on river health and the appropriateness of Nile River water for industrial, household, and agricultural purposes (Abdel-Satar et al, 2022;Al-Afify & Abdel-Satar, 2020;Othman et al, 2021).…”

“…Still, when the intake of essential metals by aquatic organisms is extremely high, hazardous effects can occur (Yacoub et al, 2021). High inputs of metals to aquatic systems can cause serious water pollution problems, resulting in potential risks to human health through the food chain (Othman et al, 2021).…”

The Rosetta Branch is one of Egypt’s most important Nile River branches, providing freshwater to multiple cities. However, its water quality has been deteriorating, with various wastes containing high loads of heavy metals being discharged into its body of water. Seasonally, water and sediment samples and two native aquatic plants (Ceratophyllum demersum and Eichhornia crassipes) were collected and analyzed from the Rosetta Branch to assess the level of metal contamination (Fe, Mn, Zn, Cu, Pb, Ni, Cd, Cr, and Co) using different metal indices. The levels of some metals in the branch water overstepped those suitable for drinking water and aquatic life. In increasing order, the means of the heavy metal concentrations in branch water (µg/L) were Cd (1.8–4.9) < Co (7.18–28.1) ≈ Ni (9.0–25.1) < Cr (8.56–27.4) < Cu (14–75) < Pb (9.3–67.9) < Zn (22–133) < Mn (68–220) < Fe (396–1640). All the metal indices measured in the sediment confirmed the Ni and Cd contamination, where Ni and Cd in the sediment surpass the sediment quality guidelines in 80% and 53% of samples, respectively, reflecting frequent adverse effects on aquatic organisms. According to the bioconcentration factor, C. demersum and E. crassipes have higher accumulation capacities mainly for Cd than those for other metals considered as major pollutants in the water and sediment of Rosetta Branch, reflecting the role of hydrophytes in the biological treatment of polluted water in aquatic environments.

“…The Nile River is Egypt's lifeblood and the primary supply of freshwater for nearly all drinking and irrigation needs in Egypt (Abdel-Satar et al 2017a). In Egypt, there are no systematic monitoring systems for recognizing and determining different types of contaminants in the Nile River ecosystem, where numerous types of organic and inorganic pollutant loading are prevalent (Al-Afify and Abdel-Satar 2020; Othman et al 2021;Shalaby et al 2018). The Nile River water quality are influenced not only by water management interventions such as the hydrodynamic regimes regulated by the Nile barrages, but also, by the land and water use, including agricultural return, industrial, municipal and river ships wastewaters.…”

Sediments are utilized as a marker for events that endure long enough to manifest their environmental impacts and determine the contamination levels. The purpose of the present study was to highlight the current sediment quality of four Nile islands shores by utilizing a variety of physical, chemical, and biological aspects and indices. In addition, the status of benthic diatoms and macroinvertebrates, as well as their responses to sediment variables were investigated. The metals followed a decreasing concentration order: Al > Fe > Mn > Zn > Ni ≈ Cr > Cu > Co > Pb > Cd. The outcomes of metal pollution indices revealed some localized contaminated sites, by mostly Ni and Cd. In addition, a moderate toxic risk from metals was observed for El-Keratten shores, while the sediments of El-Warraq, El-Zamalek, and El-Manial islands shores were at low toxic risk. A total of 112 diatom species belonging to 24 genera were identified in the total sample set, where most of the diatoms encountered were cosmopolitan. Metals had a remarkable impact on the composition, distribution, and dominance of diatom assemblages, but had little effect on diatom diversity, while there was a noticeable effect of grain size on diatom distribution and diversity. Thirty-four species of benthic invertebrates were identified in the collected samples from the islands shores. The dominant taxa and groups of benthic invertebrates at different islands were affected by various sediment parameters, where the levels and types of such variables differed from one species to another.

“…Rosetta Branch is about 225 kilometers long with an average depth of 2.0-2.3 meters. Agricultural, commercial, and domestic wastewaters, as well as anthropogenic activities, all contribute to a high microbial load on the Rosetta Branch in addition to the organic and inorganic pollutants (Othman et al, 2020). Therefore, serious negative impacts on the branch environment have been detected (Hashem et al, 2020a).…”

Water pollution is one of the most principal environmental and public health problems in the River Nile. In the present study, aims were directed to evaluate the biochemical, histopathological, and genetic effects of El-Rahawy Drain pollutants on the Nile tilapia (Oreochromis niloticus). Hence, during the summer of 2018 and winter 2019, fish samples were collected from two locations (upstream and downstream) of El-Rahawy drain in the River Nile at the Rosetta Branch. Biochemical studies (Total Protein, Albumin, Globulin, A/G, total lipids, Cholesterol, AST, and ALT) were carried out for the specimens and important results were revealed. Compared with the fish caught from the upstream, a deterioration was detected in the health status of the downstream-fish; displaying more extreme histopathological and molecular variations. Using SSR (simple sequence repeats) to detect the molecular effects of water pollutants on O. niloticus, molecular markers indicated genetic differences in fish samples from the same sex in the different studied locations. Consequently, to prevent disease outbreaks and aquatic ecosystem disturbances, the Rosetta Branch is recommended to have an intensive water-quality monitoring program, and wastewater treatment as well.
