dc.description.abstractConcentrations of major metals (Na, K, Ca, Mg) and some trace metals (Fe, Zn, Mn, Ni, Cu, Co, Pb, Cr, Cd) were determined in water, sediment, benthos and some common fish species from Lake Qarun. Water and sediment samples were collected from seven stations where, the benthos and fish species were collected from three sites representing east, middle and west of the lake. Distribution of studied metals showed that, east part generally had higher contamination than west one which may be attributed to the impact of pollution sources in this area which coming from El-Batts Drain and pumping station in the east part. Mollusca and Crustacea especially Barnacles have the highest concentrations of most heavy metals measured more than Polychaeta which make them suitable candidates to be used in biomonitoring surveys of Lake Qarun. The concentrations of heavy metals in fish samples indicate that Solea sp.and Mugil sp. seemed to be more contaminated than Tilapia sp. which attributed to their feeding behavior. Bioaccumulation factor values showed that the trend of accumulation of most metals was as follows: Mollusca > Crustacea > Annelida > Solea sp. > Mugil sp. > Tilapia sp.en
