Mesozooplankton of the Damietta Branch, River Nile, Egypt.

Polychlorinated Biphenyls Water Pollution along the River Nile, Egypt.

Ten polychlorinated biphenyl (PCB) congeners were determined in water samples collected along the River Nile using gas chromatography-electron capture detector (GC-ECD). PCB concentrations ranged from 14 to 20 μg/L, which were higher than those reported in previous studies, indicating serious PCB pollution in the River Nile. PCB congener profiles varied depending on the sampling sties. PCB-138 ...

Epidemiology of Psoriasis in Damietta Governorate, Egypt

Red Swamp Crayfish (procambarus Clarkii) in River Nile, Egypt

Dissolved organic matter status in Damietta estuary of the Nile.

The seasonal distribution of dissolved organic matter (DOM) in Damietta estuary of the Nile was investigated to show the influence of organic pollution. The DOM values increased generally with depth. The vertical values of DOM varied from 0.23-9.97 mg O/l. The average DOM values gave noticeable local variations in each month and pronounced monthly variations at each station. The maximum monthly...

Adsorption and Leaching Behavior of Copper, Zinc and Lead Ions by Three Different River Nile Sediments at Aswan, Egypt

The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...
