“…All three plants have a higher TF than 1.0 for the five heavy metals, which indicates that all three plants can effectively transfer heavy metals to the above-ground parts and facilitate the bioextraction of soil heavy metals. The BCF can be used to assess the potential for phytoremediation [ 40 ]. From Figure 2 it is clear that none of the three plants had a BCF for the five heavy metals greater than 1.0.…”

“…Root Mn was also the highest in pre-monsoon summers with <1 BCF on all study sites but never exceeded the permissible limit of 50 mg kg −1 in any season [ 49 , 50 , 51 ]. Both Fe and Mn are micronutrients and are essentially needed by components of plant antioxidant enzymes in several physiological and biochemical functions [ 52 , 53 , 54 ]. If found well within the suggested ‘normal ranges’, Fe and Mn could be beneficial for plant growth, otherwise damaging in the case of toxic concentrations [ 54 ].…”

“…However, phytoextraction applications must combine several characteristics, particularly a high metal translocation rate from roots to shoots, and ideally a hyperaccumulating ability, as recommended by the authors. Most of halophytes accumulate metals in the roots, and only rare halophyte species are considered to be metal hyperaccumulators [67,68]. Anyhow, the choice of halophyte species that rather belong to salt includers, ideally capable of accumulating metals in shoots and in roots, is relevant in the development of phytoremediation applications [54,69].…”

“…For instance, Arthrocnemum can accumulate 724 mg/kg DW of Pb [78]. Salsola kali, a desert halophyte, can bear 2075 mg/kg Cd in the stems and 2016 mg/kg Cd in the leaves [79] and may be classified as "obligate hyperaccumulators" according to Aziz and Mujeeb [68]. The desert halophylic Suaeda fructicosa can accumulate 1379 mg/kg Cr and a maximum of 13,246 mg/kg Na in the shoots, while soil concentrations were 19.5 mg/kg [80].…”
