In the last decades, Manzala Lagoon suffered from pollution types’ either from agriculture,
sewage or industrial wastes that turned the lagoon into polluted, unhealthy ecosystem affecting
fish production and natural resources that distributed within the lagoon. To quantify the
pollu-tion status in the northeastern part of Manzala lagoon, water and sediment samples were
collect-ed from fourteen sites covering the study area during winter and spring seasons 2011 and
ana-lyzed for determination of some physicochemical parameters and heavy metals (Pb, Cd, Zn, Cu
and Mn). Results showed that non-biodegradable pollutants were appeared to be more as a
re-sult of industrial drainage that concentrated in the area. Heavy metals concentrations are high
in hot seasons except for zinc in water; copper and cadmium in sediment which showed a
re-verse trend. Heavy metal pollution affects not only the health status of the aquatic ecosystem,
but also public health as a result of bioaccumulation in the food chain; So awareness should be
introduced to people in area and new techniques must be used to overcome pollution, especially
heavy metals.
