N2  - Five sites in the water of Rosetta Branch were selected to investigate the physical (temperature), water chemical characteristics such as pH, electrical conductivity, cations (calcium, magnesium, sodium and potassium), anions (chloride, bicarbonate and sulfate) and heavy metal concentrations. In this study there are great variations in the studied parameters according to the distance from the source of pollution. Heavy metal concentrations are strongly affected by the industrial effluents produced from each of El-Mobidat, El-Malyia and Salt and Soda companies which directly discharge industrial effluents at this area without any treatments. The correlation coefficient and regression analysis between concentrations of heavy metals in muscles of each of the studied fishes; bulti, bayad, and catfish and the concentrations of these heavy metals in water were studied. There are significant positive correlation at (p {u2264} 0.05) between the concentrations of each of Fe and Mn in water and the muscles of each of bulti and catfish, respectively. On the other hand, there were significant negative correlation at (p {u2264} 0.05) between the concentrations of each of Cu and Cd in water and the concentration of these metals in the muscles of each of bulti and catfish
