Abstract

An experiment was carried out at Serapium plantation located in northeastern Egypt on March 2019, 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 six 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.
