Abstract
The present study highlighted the floristic and ecological features of three contaminated drain systems namely El-Westany, Amar and Omar-Beck. These drains are located within the boundaries of the Nile Delta region of Egypt. In addition, the concentrations of heavy metals in both soil (sediment) and water were investigated to determine the degree of contamination. Finally, the phytoremediation potential of six species predominates in the study drains were investigated to define their ability to phytoextract or phytostabilize high concentrations of heavy metals. The present study aims at the following objectives: 1) Define the major drain water bodies in the north of the Nile Delta region, Egypt. 2) Identify the floristic composition and features in the study drains system. 3) Vegetation analysis using the multivariate techniques (TWINSPAN and DCA) to recognize the plant clusters/groups in the study area. 4) Analysis of variation in hydrosoil (sediment) and water factors, followed by application of CCA to determine the most important factors controlling the distribution of plants in the study area. 5) Phytochemical analysis (primary constituents and secondary metabolites), minerals and heavy metal determination for some selected plant species in the studied drains. 6) Evaluation of phytoremediation efficiency of the selected plant species in the study drains by calculation of bioaccumulation factor (BAF) and translocation factor (TF) for their shoots and roots. The current study included three main sections: floristic-ecological features, phytochemical analysis and phytoremediation measures for six plant species.
