“…The calculated bioaccumulation factors ( Translocation factors (Table 3) ranged from 0.24 to 0.35 for leaves and from 0.18 to 0.46 for stems in agreement with reported translocation factors for Cr using other plants that did not reach the value of 1.0 (Zhang et al, 2007;Buendia-Gonzalez et al, 2010) . The low translocation factors of Cr observed in P. oleracea are likely to be due to the stress of highly oxidative Cr(VI) species which would cause severe damage to plant tissues, especially roots.…”

Cr(VI) represents an environmental challenge in both soils and waters as it is soluble and bioavailable over a wide range of pH. In previous investigations, Portulaca oleracea (a plant local to the UAE) demonstrated particular ability for the phytoextraction of Cr(VI) from calcareous soils of the UAE. In this publication, the results of the evaluation of P. oleracea phytoextraction of Cr(VI) from UAE soil at higher concentrations are reported. P. oleracea was exposed to nine different concentrations of Cr(VI) in soil from 0 to 400 mg kg -1 . The uptake of Cr(VI) increased as its concentration in soil increased between 50 and 400 mg kg -1 , with the most efficient removal in the range from 150 to 200 mg kg -1 . The total chromium concentrations exceeded 4600 mg kg -1 in roots and 1400 mg kg -1 in stems, confirming the role of P. oleracea as an effective Cr(VI) accumulator. More than 95% of the accumulated Cr(VI) was reduced to the less toxic Cr(III) within the plant.

“…The remediation of HM-contaminated soil refers to using physical, chemical, biological, or combined methods to transfer or absorb HMs and reduce their concentrations to below harmful levels (Buendia-Gonzalez et al, 2010). The main physical and chemical remediation technologies are curing stability, leaching, chemical oxidation–reduction and soil electrokinetic remediation (Wu, 2015; Zhang, 2015).…”

Heavy metal (HM) pollution is a global environmental problem that threatens ecosystem and human health. Cadmium (Cd) pollution is the most prominent HM pollution type because of its high toxicity, strong migration, and the large polluted area globally. Phytoremediation of contaminated soil is frequently practiced because of its cost-effectiveness and operability and because it has no associated secondary pollution. High-accumulation plants, including those identified as hyperaccumulators, play an important role in phytoremediation. Therefore, screening of plants to identify hyperaccumulators is important for continued phytoremediation. In the present study, we investigated the Cd tolerance and accumulation capabilities of 18 turnip landraces from China under a soil experiment with known Cd level. The results indicated that turnip has a high capacity for Cd accumulation. Furthermore, significant differences in Cd tolerance and accumulation characteristics were found among different landraces when they grew at 50 mg kg-1 (dry weight) Cd concentration. Among the studied landraces, five turnip landraces met the requirements of Cd hyperaccumulators and three landraces were identified as potential candidates. However, the total Cd content accumulated by individual plant of different turnip landraces was dependent on both the Cd accumulation capacity and plant biomass. Compared with some reported Cd hyperaccumulators, turnip not only shows a high Cd-accumulation capacity but also has rapid growth and a wide distribution area. These advantages indicate that turnip may have considerable potential for phytoremediation of Cd-contaminated soil. Furthermore, the study also indicates that it is not advisable to consume turnip cultivated in an environment that exceeds safe Cd levels.
