Evaluation of Halocnemum strobilaceum and Hammada scoparia plants performance for contaminated soil phytoremediation

The potential of Hammada scoparia (Hamm.) and Halocnemum Strobilaceum (Halo.) growing in BenghaziLibya for soil phytoremediation purpose has been evaluated. Hammada scoparia (Hamm.) and Halocnemum Strobilaceum (Halo.) and their roots soil samples were collected and analyzed for Cd, Ni and Pb concentrations in a salty area in the north coastal region of Benghazi, near Benghazi asphalt factory, Benghazi steel factory, Brega oil company sorage tanks, and north Benghazi power station. The biological absorption coefficient (BAC), bioconcentration factor (BCF), and translocation factor (TF) of Hammada scoparia and Halocnemum Strobilaceum have been calculated. Both plants are moderate extractor, they tend to phytoextraction process except Halo tends strongly to phytostabiliztion process in case of Cu and Fe.
