| description | The current study addressed the heavy metals accumulation potentials of seven perennial aquatic macrophytes (<i>Cyperus alopecuroides</i>, <i>Echinochloa stagnina</i>, <i>Eichhornia crassipes</i>, <i>Ludwigia stolonifera</i>, <i>Phragmites australis</i>, <i>Ranunculus sceleratus</i> and <i>Typha domingensis</i>) and the pollution status of three drains (Amar, El-Westany and Omar-Beck) in the Nile Delta of Egypt. Nine sites at each drain were sampled for sediment and plant analyses. Concentrations of eight metals (Fe, Cu, Zn, Mn, Co, Cd, Ni, and Pb) were determined in the sediment and the aboveground and belowground tissues of the selected macrophytes. Bioaccumulation factor (BF) and translocation factor (TF) were computed for each species. The sediment heavy metals concentrations of the three drains occurred in the following order: El-Westany > Amar > Omar-Beck. The concentrations of sediment heavy metals in the three drains were ordered as follows: Fe (438.45–615.17 mg kg<sup>−1</sup>) > Mn (341.22–481.09 mg kg<sup>−1</sup>) > Zn (245.08–383.19 mg kg<sup>−1</sup>) > Cu (205.41–289.56 mg kg<sup>−1</sup>) > Pb (31.49–97.73 mg kg<sup>−1</sup>) > Cd (13.97–55.99 mg kg<sup>−1</sup>) > Ni (14.36–39.34 mg kg<sup>−1</sup>) > Co (1.25–3.51 mg kg<sup>−1</sup>). The sediment exceeded the worldwide permissible ranges of Cu, Zn and Pb, but ranged within safe limits for Mn, Cd, Ni and Co. <i>P. australis</i> accumulated the highest concentrations of Fe, Co, Cd and Ni, while <i>E. crassipes</i> contained the highest concentrations of Cu, Zn, Mn, and Pb. Except for <i>C. alopecuroides</i> and Cu metal, the studied species had BF values greater than one for the investigated heavy metals. Nevertheless, the TFs of all species (except Cd in <i>L. stolonifera</i>) were less than one. Hence, the studied species are appropriate for accumulation, biomonitoring, and phytostabilization of the investigated metals. |
