Abstract

An experiment was carried out at Serapium plantation located in northeastern Egypt on March 2020, to study the phytoremediation capability and mineral content [Nitrogen (N), Phosphorus (P) and Potassium (K)], of three tree species Tectona grandis , Gmelina arborea and Azadirachta indica irrigated with treated sewage water after 7 years of planting in two sites at Serapium plantation, one of the two sites was planted for first time (afforestation in site1) and the other was replanting (reforestation in site2) . Results showed after a period of using treated sewage water irrigation that the concentration of heavy metals in soil was not severe at the two sites. Phyto-Extraction capacity of Tectona grandis was the superior for Zinc (Zn), Iron (Fe) and lead (Pb), respectively. Noticeable, that all the studied species are considered hyperaccumulators, allusion to their Phyto-Extraction Ratio.
