Phytoextraction by Moso Bamboo under high level chromium stress in mediterranean conditionsPhytoextraction by Moso Bamboo under high level chromium stress in mediterranean conditions Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2024-01-172022enIn this study a bamboo species, Moso Bamboo (MB) – Phyllostachys pubescens – has been selected for its heavy metal accumulation capacity and translocation potential to restore Cr-contaminated soil. Experiments have been conducted so to evaluate the capability of MB to remove Cr from soil, growing under Mediterranean conditions, irrigated with water containing 180 mgCr/L, at flow rate of 600 mm/year. The soil has been contaminated by the irrigation water. When the concentration of Cr in soil reached 300 mgCr/kg, Cr phytoextraction by MB from soil at the same irrigation rate of 600 mm/year with uncontaminated water has been evaluated. Cr removal from soil was approx. 42% after 6 weeks and 60.7% after 12 weeks, starting from a Cr content in soil of approximately 300 mg/kg. MB growing in Cr contaminated soil has shown Cr concentration per gram of dry biomass in aerial parts greater than the underground parts of the plants. After 12 weeks of cultivation, the quantity of Cr in roots and rhizome was measured as 1.79 mg/g, while in stems and leaves as 2.49 mg/g. Results shown a bioconcentration factor of 0.77, 0.65, 0.18, 0.08, after 6 weeks and 0.64, 0.98, 0.53, 0.26 after 12 weeks for roots, rhizomes, stems and leaves, respectively and a translocation factor equal to 0.23 and 0.11 after 6 weeks and 0.83 and 0.40 after 12 weeks, for stems and leaves, respectively.http://creativecommons.org/licenses/by/4.0/Journal of Environmental Management317 Ranieri Ezio Gikas Petros Γκικας Πετρος Ranieri Francesca D'Onghia, Gianfranco Ranieri Ada Cristina Elsevier Bamboo growth Tolerance Chromium removal Metals translocation Phytoextraction
