Adsorption of Wheat and Maize on Heavy Metals in Soils
To probe adsorption of several heavy metals in soils that had been irrigated by wastewater by wheat and maize,several samples of both soils and the plant tissues were taken simultaneously.The samples of various parts for the crops were analyzed in laboratory.It has been discovered that accumulation ability of heavy metals Zn,Cu,Pb and Cd by the studied plants tissues were in an order roots＞leaves＞stems＞ seeds.In addition,accumulation of the heavy metals was in an order: Zn＞Cu＞Pb＞Cd,for wheat,while Cu＞Zn＞Pb＞Cd for maize,respectively.
