The accumulated levels of Zn and Pb were determined in organs (muscles, liver and gill) of fish (T. zilii and M. capito) caught from eastern, middle and western part of Qarun lake in four seasons. Results revealed that Zn concentrations were greater than Pb in fish species tissues from the eastern, middle and western part. The lowest accumulated values of Zn and Pb were in the muscle, while the highest values were in the liver in two fish species. Also, accumulation of Zn and Pb in the tissue of both fish species takes the order: liver< gill
