Ahmed Mohamed Sultan, Adnan Hussein Ali alwakaa, Hanan Haqi Ismael


Carried out this study in the College of Agriculture and forestry / Mosul University during growing season of the water hyacinth Eichhornia crassipes (Mart)Solms  for 2012 included the experiment two factors , first the quality of the water and second time periods of sampling where the measurement of the proportion of heavy elements from the stream of the valley of the Al-Kraze , which is in the effluent  of AL-kosar , and then the Tigris River .in a week if I took samples of the water before entering the receptacle of cultivated plants is the water hyacinth, and then take samples after the presence of water with the plants for two days . Showed results high efficiency water hyacinth in the absorption of mineral elements including heavy with salts with modification number  the EC of the water course of the valley of the Al-Kraze, where it is absorbed by the water entering into the zone of plant growth through the summer months quantities of salinity, nitrate, phosphate, copper, zinc, lead and cadmium of up to 6,4٪ , 55,9٪ , 38,7٪ , 65,8٪ , 51,3٪ , 51,9٪ , 65,6٪ respectively also reduced the number the pH of the water at a rate of 0,21 . Although there is variation in the rates of salinity and the elements present in the water during the time periods of July to September , it has obsorp the plant higher amounts of the element of copper, lead and cadmium in the month of September, while, obsorp the highest level of salinity, nitrate, phosphorus, and zinc, in the month of July .

Keywords: pollution, Eichhornia crassipes (Mart)Solms , period of time, quality of water, waste water, heavy metal
