Evaluation potentiality of Rhizophora mucronata plantation for pollutants remediation on the Red Sea Coast, Egypt

Abstract The planted Rhizophora mucronata was evaluated in two plant ages (one year and eight years) as a biological tool for reducing the mobility of heavy metals sediments Safaga Hamata, Red Sea Coast, Egypt. It is an important region tourism nature reserves; however, this area suffers from various anthropogenic contaminants. ability mangrove plantations to reduce sediment contamination through bioaccumulation, phytostabilization, or phytoextraction must be clarified investigation metal behavior plants sediments. All studied had significantly higher concentrations site's Elder much lower levels their than younger plants, also rhizosphere samples were less contaminated non-rhizosphere ones. order remediation efficiency Mo > Ni Mn ≥ Co Al Cu Zn Cr Fe V, where highest % 99.25, 58.97, 42.64, 42.48, 41.91, 39.47, 37.93, 37.01, 36.89, 29.44, respectively. R. parts more with Co, Cr, Cu, site, while at Hamata they Al, Fe, Mn, Ni, V. elder accumulated ones contents followed root aerial roots shoot. Bioconcentration factor (BCF) values representing accumulation V 17.74, 7.89, 3.95, 3.84, 2.66, 1.91, 1.67, 1.66, 1.6, 1.18, BCF exceeded one all translocation (TF) unity cases, thus can considered good phytostabilizer ten able by roots, thereby off-site contamination.
