Abstract

In the present study, six native halophytes were collected from soil of northern Nile Delta to evaluate their phytoremediation potential of heavy metals. For this purpose, soil, the aboveground parts and roots of the samples were analyzed for total concentrations of Fe, Pb, Ni, Co and Cd using atomic absorption spectrometer. The concentrations of different heavy metals in soils have the sequence of Fe>Ni>Pb>Co>Cd. The pollution quantification for each metal in the study area indicated that, the extremely high enrichment value for Cd; very high enrichment values for Pb and Co and low enrichment values for Ni and Fe; The contamination factor has very high for Cd; moderate for Pb and Co and low for Ni and Fe, while the contamination degree (CD) indicates that the study area is considered to be coast with low to moderate contamination degree (2.74 and 10.29). In the study area, the concentrations of heavy metals in plant species have the order of Fe>Pb> Ni>Cd >Co. Most plant species had a TF<1 for Fe, Ni, Co and Cd except Pb>1, while the BAF values for Fe, Pb, Ni, Co and Cd were <1, except BAF root of A. halimus, L. pruinosum and S. pruinosa were >1. The highest BAF shoot and root values was observed in Atriplex halimus, while the lowest was for Suaeda maritima. Similarly, the highest TF values were observed for Z. aegyptium, S. pruinosa and L. monopetalum, while the lowest was for S. pruinosa. Results suggest that these plants could be suitable for use in the phytoremediation of contaminated soil sites.
