| Abstract | ||
| This study was conducted to assess the levels of some heavy metals (copper, lead, cadmium and chromium) in water and sediments of Ismailia canal, El-Bagoria canal and Drainage No. 1, and their accumulated effects in tilapia fish and berseem plant and its implication on both human and animal health. The highest copper values were detected at Ismailia canal where its level reaches 0.32mg/I at 1st site, while the lowest copper values were detected in all sites of Drainage No.1. Low concentrations of Cu were found in muscles while, the highest concentrations were found in liver. The highest level of Pb was detected at 3rd site of Ismailia canal where it reached 7.72 and 1.25 µg /g in liver and muscles tissues, respectively. While the Pb was not detected totally in liver tissue, in 3rd site of El-Bagoria canal and in muscles tissues in 1st site of Drainage No.1. It could be also noticed that the highest level of Cd in berseem was (0.65 mg/kg) detected in 2nd site of El-Bagoria canal, while Cd level was not detected in all sites of Drainage No.1.It is recommended from this study that the areas of heavy pollution along the River Nile should be under control to prevent access to the water with increasing frequency of cleaning of the canals, minimizing the rate of obstruction of the canals; public awareness should be applied to prevent unhygienic practices, which imposes a major health risk. Avoid fish market from polluted areas. | ||
