الملخص EN

The study showed that the Zn concentration in the water is (53.4,47.1, 33.1, 12.1) μgL¯¹ in the four stations respectively .while the concentration of Cd were (11.4,10.4, 10, 9.2) μgL¯¹ in the four stations respectively.

Zn concentration was (11.13) μgg¯¹ and Cd concentration (79.6) μgg¯¹ in the sediments of first station, while the concentrations of Zn and Cd (100 , 66.4) μg g¯¹ in the second station respectively.

The showed that the highest rates of concentrations of Zn and Cd in the first station in the waters (53.4 , 11.4) μgL¯¹ respectively and the sediment (111.3, 79.6) μgg¯¹ respectively.

But the fourth station showed little bit to these elements during the present period of study, the highest concentration of Zn in the tissue of gills, liver and kidney in the first station were (111.4 ,76.1 ,54.3) μgg¯¹ respectively.

while no Sensitivity was observed in four station.

kidney tissue recorded the lowest value levels of those values comparison with the other organs.

The analysis of basic components of the tissues showed the correlation in second station (0.08%) in the pollution of liver and gills of the fish with Ca and Zn while the fourth station was less polluted since was weekly correlated with all pollutants.
