Abstract
The purpose of this study is to investigate the impact of long-term irrigation with low-quality water resources (wastewater) on the accumulation of potentially toxic elements (PTEs) in some edible plants (date palm (Phoenix dactylifera L), olive, pomegranate, eggplant, pepper, wheat and clover) as well as casuarina trees and iceplant (Mesembryanthemum crystallinum L.). Water, soil and plant were collected from Kalabsho, Dakahlia chemical properties and PTEs concentration. The prevalence of PTEs concentration in wastewater was higher in summer compared to autumn and winter seasons. Concentrations of PTEs in wastewater ranked were: (i) Zn>Fe>Al>Cu>Ni>Mn with, Co, Cd, Pb and Cr not detected (ND) during the autumn, (ii) Mn>Zn>Fe>Al>Ni>Pb>Cu whereas, Co, Cd and Cr were ND during summer, and (iii) Zn>Al>Fe>Mn>Ni while, Co, Cd, Cu, Pb and Cr were ND during winter. Similarly, Mn showed highest concentration in soil. In all cases, the levels of PTEs concentrations in water and soil were within allowable limits of FAO/WHO. Concentrations of PTEs were above maximum allowable limits except Ni and Cu in olive young leaves, casuarina young and old needles as well as pepper leaves. The accumulation characteristics of clover and iceplant has proven their potentiality in phytoremediation of PTEs contaminated soil. General, PTEs concentrations were within the permissible limits in water and soil but above the maximum allowable limit in plants except Ni. The bioaccumulation factor (BCF) was >1.0 in all PTEs under consideration. Findings from this investigation increased our understanding regarding ecotoxicological hazard of PTEs in marginal soils irrigated with low-quality water resources.
