“…As bauxite residue is relatively similar to saline-sodic soils, halophytes show the greatest potential to achieve rehabilitation . Some studies have demonstrated that halophytes including Terminalia arjuna, Pongamia pinnata, and Pennisetum pedicellatum can be used to establish in the rehabilitated residues (Chauhan and Ganguly 2011;Alshaal et al 2013). These halophytes have high tolerance to salinity and alkalinity and have the ability to remove Na + and decrease the exchangeable sodium percentage.…”

Bauxite residue (Red mud) is produced in alumina plants by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The global residue inventory reached an estimated 3.5 billion tons in 2014, increasing by approximately 120 million tons per annum. The appropriate management of bauxite residue is becoming a global environmental concern following increased awareness of the need for environmental protection. Establishment of a vegetation cover is the most promising way forward for the management of bauxite residue, although its physical and chemical properties can limit plant growth due to high alkalinity and salinity, low hydraulic conductivity, trace element toxicity (Al and Fe), and deficiencies in organic matter and nutrition concentrations. This paper discusses the various revegetation and rehabilitation strategies. Studies of the rehabilitation of bauxite residues have mainly focused on two approaches, amelioration of the surface layer and screening of tolerant plants and soil microorganisms. Amendment with gypsum can reduce the high alkalinity and salinity, promote soil aggregation, and increase the hydraulic conductivity of bauxite residues. Organic matter can provide a source of plant nutrients, form stable complexes with metal cations, promote hydraulic conductivity, stabilize soil structure, and provide an energy source for soil organisms. Tolerant plants and microorganisms such as halophytes and alkaliphilic microbes show the greatest potential to ameliorate bauxite residues. However, during restoration or as a result of natural vegetation establishment, soil formation becomes a critical issue and an improved understanding of the various pedogenic processes are required, and future direction should focus on this area.

“…Recently, this plant has been used in phytoremediation, in particular, for P, Cd and Ni uptake potential and biomass production for energy purposes in contaminated sites. There are several works concerning the promising phytoremediation giant reed (Table 4.

“…These late shoots develop at a faster rate and attain the same height as the early ones, though the leaves are smaller and the stem diameter is much larger -as much as twice as large (El-Bassam and Dalianis 2010 ).

“…As a consequence of its high and fast biological productivity, giant reed is widely cultivated to yield non-food crop (Papazoglou et al 2005 ) that can meet requirements for energy, paper pulp production, biofuels and construction of build materials but it has other different uses such as music tools with stem, medicine with roots and soil erosion control through re-vegetation (Nassi et al 2010 ). However, because of its great adaptability to different ecological conditions, giant reed is also one of the most noxious invasive weeds, widely distributed in riparian habitats throughout the world (Bonanno 2012 ) as reviewed by Alshaal et al ( 2013 ).…”

Levels of Tl (Thallium) in soil from 0 (control) to 50 µg/L through 0.2, 0.5, 1 and 2.5 µg/L were directly and positively correlated to levels of Tl in plant tissue, the accumulation being maximum in roots, intermediate in leaves and minimum in stems. Thallium, especially at higher concentrations, adversely affected photosynthesis (as judged based on chlorophyll fluorescence parameters), suggesting inhibition of photo-activation of PSII (Photosystems II), and also decreased the rate of photosynthesis, the rate of transpiration and stomatal conductivity drastically. Exposure to Tl also increased the activity of CAT (Catalase) (except at 1 µg/L) and POD (Peroxidase) (except at 0.2 µg/L), suggesting that the antioxidant systems in Coix lacryma-jobi were the main contributors of CAT and SOD (Superoxide Dismutase) and that the tolerance of C. lacryma-jobi to Tl is mainly due to this induced antioxidant machinery.
