Chemical pollution of Manzala lake was studied in 4 main localities, Kapoty, Bashtier, Mataryia and Gamil areas which receives high load of sewage, agricultural and industrial wastes from different sources. Heavy metals, such as Zn, Pb, Cd and Hg were estimated in water and fish samples, to reveal high pollution of lake Manzala with such toxic elements, where Zn, reached 800µg/L. Pb,195 µg/L. Cd 45 µg/L and. Hg, 5000 µg/L in water samples.
