Heavy metals concentrations in water and fish of some Egyptian lakes and fishponds [electronic resource].

Includes references.

Five heavy metals namely, cadmium, copper, iron, lead, and zinc were determined in water and fish samples obtained from three different lakes and fishponds in Egypt over nine months to assess pollution with those toxic metals. Water and fish (Tilapia sp.) samples were collected from Abbassa fishpond, Lake Qaroun, and Wadi EI-Rayan Lake. The results showed that concentrations of the five metals varied significantly among sites and seasons. Concentrations of iron, copper and zinc were slightly higher than lead and cadmium concentrations in water samples from the three sites.
