LEAD AND CADMIUM CONTENTS IN NILE WATER, TILAPIA AND CATFISH FROM ROSETTA BRANCH, RIVER NILE, EGYPT.

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...

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 ...

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

Developing a Cell Culture System from Nile Tilapia (Oreochromis Niloticus, L.) Ovarian Tissue in Egypt

Cell culture from ovarian tissue of healthy female fingerlings Oreochromis niloticus was established with average weight of 20 to 30 gm/female. Three culture media were screened and tested: Leibowitz L-15), Minimum essential medium (MEM) and RPMI 1640 medium. Cells were maintained at 16, 27 or 30C for screening the favorable optimally incubation temperature. Culture medium was refreshed every 5...
