| The purpose of this study is to gather the information on the aquatic ecosystem of the River Nile at El -Qanater El Khayreyya region,El-Qalyubia governorate and El-Mariotya canal, El-Giza governorate and to investigate the effectiveness of water hyacinth as adsorbent to remove some heavy metals from water. Also, the heavy metals (Cd, Cu, Fe, Pb and Zn) in water, sediment and water hyacinth plant samples was determined using atomic absorption spectrophotometry. The heavy metal levels in water samples ranged between (0.945±0.214 to 3.025±0.210 μg/L) for cadmium, while, copper levels were from (8.296±1.692 to 20.529±2.135 μg/L). Also, concentration of iron ranged (150.94±1.682 to 412.84±2.376 μg/L), while the concentrations of lead were (0.922±0.185 to 4.365±0.458 μg/L) and zinc concentrations ranged between (3.979±0.264 to 7.057±0.500 μg/L) in El-Marutia canal and El-Qanater El-Khayreya region during all seasons. Also, the heavy metal levels in sediment samples ranged between (11.18±0.98 to 18.19±1.57 μg/g) for Cd and varied between (10.58±2.18 to 52.2±3.64 μg/g) for Cu. While, iron concentration varied from (207.11±3.99 to 700.4±4.32 μg/g). On the other hand, Pb ASSESSMENT OF THE HEAVY METALS POLLUTION IN370 concentrations ranged between (7.08±1.95 to 24.28±2.31 μg/g) and Zn levels was ranged between (23.54±3.85 a to 74.52±2.09 μg/g) during all seasons in El-Marutia canal and El-Qanater region. The range of cadmium in water hyacinth plant was between (12.94±2.34 to 29.83±0.69 μg/g), (8.82±1.25 to 16.73±2.05 μg/g) and (1.78±2.82 to 10.28±2.01 μg/g) for root, and leaves samples, respectively during all seasons in El-Marutia canal and El-Qanater El- Khayreya region. While Cu concentrations were (22.22±2.61 to 71.93±1.59 μg/g), (15.97±3.54 to 50.45±4.19 μg/g) and (13.73±3.47 to 45.40±1.4 μg/g) for root, and leaves samples, respectively during all seasons in El-Marutia canal and El-Qanater El-Khayreya region. Concentrations of Fe in roots, shoots and leaves samples were ranged from (96.7±4.06 to 185.31±1.5 μg/g), (85.26±3.5 to 115.13±1.4 μg/g) and (74.88±5.0 to 108.7±3.4 μg/g), respectively. Also, lead concentrations in roots, shoots and leaves samples were ranged from (6.22±6.24 to 13.51±0.96 μg/g), (4.22±2.57 to 11.49±5.08 μg/g) and (2.1±2.06 to 7.17±2.39 μg/g), respectively, while Zn concentrations were (6.98±3.25 to 18.30±3.31 μg/g), (3.95±4.69 to 13.03±2.17 μg/g) and (2.49±6.21 to 6.65±3.58 μg/g) for roots, shoots and leaves samples, respectively | ||||
