The aim of this study was to investigate the phytoremediation potential promoted by Baccharis dracunculifolia DC. and Baccharis trimera (Less.) DC. incopper mining tailings area, Southern Brazil. The plants were selected considering their spontaneous growth on tailings. The phytoremediation indexes as a translocation factor (TF), bioconcentration factor (BCF), metal extraction ratio (MER) and plant effective number (PEN) were carried out. Both species showed higher concentration of heavy metals in the roots in relation to the shoots. B. trimera showed potential for phytoextraction of Zn, Cd, Cr, Pb and phytostabilization of Ba and Ni, whereas B. dracunculifolia showed potential for phytoextraction Pb and phytostabilization of Cu, Zn, and Ba. B. trimera showed higher potential in phytoremediation of the metals Cu > Zn > Cr > Ni and Cd than the B. dracunculifolia. B. trimera requires a smaller number of plants to remove 1 g of Cu, Zn, Cr, Pb, Niand Cd than the B. dracunculifolia. The values of PENs for Cu were close to those estimated for B. dracunculifolia, but the PENs (Cu) and PENt (Cu) in B. trimera are much lower, meaning that a smaller number of plants are required for decontamination. Both species showed potential for phytoremediation of metals and grew spontaneously in the tailing mining area.

“…Nevertheless, the translocation factor (TF) of Cu was correlated negatively with the stem diameter (-0.81) and the biomass of the roots (-0.75). Cu is an essential micronutrient, even though it can be toxic above certain levels (Barbosa et al 2013;Andreazza et al 2015;Silva et al 2015). Cadmium (Cd) in the shoots of sunflower had negative correlations with stem diameter (-0.69) and the biomass production of the roots (-0.63).…”

Purpose The purpose of this work was to evaluate the impacts of the amendment of industrial landfill sludge (ILS) in two different soils with cultivation of sunflower and sorghum plants. Methods The plants grew in two types of soils (Typic Paleudult-TP, and Grossarenic Hapludult-GH) with different doses of ILS (0, 2, 5, 10, and 20 Mg ha −1). The evaluation of the pH, electrical conductivity, available concentrations of P, K, Ca, Mg, and Na, and the hydrolysis of FDA in the soils were tested. The height and dry mass of both plants were measured, as well as the stem diameter of the sunflower. The total concentration of Cu, Cd, Cr, and Pb was evaluated in the plants and soils, in addition to the translocation factor of those in the plants. Results The amendment of ILS in the soils was efficient to increase the pH and macronutrients, as to increase the biomass production. The largest production occurred with 10 Mg ha −1 , and the highest dose (20 Mg ha −1) had negative effects in all treatments. Both plants had low accumulation of Cu, Cd, and Pb in their tissues. Cr increased in the roots of sunflower plants (especially in the TP soil) without translocation to the shoots. Conclusions The amendment of ILS in soils is an alternative to disposal with benefits to plants and soil quality. TP soil presented better results, being more secure to receive the sludge due to its higher content of clay when compared to the GH soil.

“…Considering the strategies employed in phytostabilization, plants that can appropriately fall under this mechanism is their ability to tolerate and immobilize metals and other contaminants, low translocation capacity from root to plant aerial parts and of course extensive and fibrous tap root system [7]. Among several studies that reported plants species with these characteristics [47][48][49] demonstrating the phytostabilization of Zn, Pb, Cu and Cd by different plants in soil and sediment polluted environments.…”

The continued accumulation of trace and heavy metals in the environment presents a significant danger to biota health, including humans, which is undoubtedly undermining global environmental sustainability initiatives. Consequently, the need for efficient remediation technologies becomes imperative. Phytoremediation is one of the most viable options in this regard. Hundreds of plants in laboratory experiments demonstrate the potential to remediate varying concentrations of heavy metals; however, the remediation capacity of most of these plants proved unsatisfactory under field conditions. The identification and selection of plants with higher metal uptake capacity or hyperaccumulators are one of the limitations of this technology. Additionally, the mechanism of heavy metal uptake by plants remains to be sufficiently documented. The halophyte plants are famous for their adaptation to harsh environmental conditions, and hence could be the most suitable candidates for heavy metal hyperaccumulation. The state of Qatar in the Gulf region encompasses rich resources of halophytes that have the potential for future investment toward human and environmental health. This chapter, therefore, gives an overview of phytoremediation, with emphasis on halophytes as suitable heavy metal hyperaccumulators for improved remediation of heavy metal-contaminated areas.
