Studying the effect of sewage water irrigation on the mineral composition of Purslane plants

ABSTRACT Six sites of different farms in Mosul district (Sherikhan village, Shur valley, Aden, Al Atabaa, Jerf Al Malleh and Furgan areas) which Purslane plants in these farms were irrigated by Wells, sewage or industrial and domestic waste water. The results of this study showed that there was a significant increase in the four heavy metals Cd, Pb, Ni and Zn content of the irrigation water mainly in Shur valley water, in the other hand there was an increase in the soil and plant content of the heavy metals with a significant decrease in nutrient metal concentrations in the growing plants in Aden area, while there was a decrease in the heavy metal concentration in the soil and water, In addition there was a significant increase in nutrient metal concentration in the growing plants in Sherikhan village which were irrigated with wells water in comparison with the other sites of the study.
