“…A poluição antropogénica aumentou drasticamente no último século [5,6]. Os impactos negativos dos poluentes sobre a biodiversidade não se limitam a níveis tróficos específicos, mas afetam a estrutura e o funcionamento das redes alimentares [6,45]. Ao contrário de outras espécies químicas, os metais pesados no solo são estáveis e não sofrem praticamente degradação biológica ou química e, por isso, persistem ao longo de muito tempo, mesmo que a fonte de contaminação seja removida [7,46].…”

“…Halophytes are generally tolerant to heavy metals compared to prevalent crops (Manousaki and Kalogerakis 2011).The ability of halophytic crops to synthesize organic compatible solutes may allow them to tolerate heavy metals as HMs cause both secondary water stress and oxidative stress in plants (Manousaki and Kalogerakis 2011;Naikoo et al 2019). Proline accumulation has a significantly beneficial role in metal stress tolerance through metal binding, antioxidant defense, and signaling under osmotic stress (Dar et al 2016).…”

“…In general, surplus heavy metals are stored and concomitantly detoxified within the vacuole (Martinoia et al 2007). ABC (ATP-binding cassette), CDF (cation diffusion facilitators), P1B-type ATPases, CAX, and NRAMP (natural resistance macrophage) transporters are the primary families engaged in vacuole metal sequestration (Naikoo et al 2019;DalCorso et al 2013;Kushwaha et al 2016).…”

Halophytic plants thrive well in the environments characterized by excess salt ions, even at toxic concentration, particularly sodium and chloride, due to their efficient biochemical tolerance mechanisms. These adaptation mechanisms may not be limited to high salt concentrations but may confer tolerance to other toxic ions, including heavy metals. Several studies have documented the ability of halophytes to tolerate and accumulate high levels of heavy metals, making them excellent candidates for phytoremediation of contaminated soils. This chapter details the overview of halophytes in India and their phytoremediation strategies.

“…Contamination with potentially toxic elements (PTEs) (also described as “heavy metals and metalloids”) is a global concern due to their nonbiodegradable nature and persistence in different environmental compartments [ 1 , 2 ]. In addition, the presence of anomalous concentrations of trace metals in the environment is of great ecological importance, since these elements tend to bioaccumulate and biomagnify through the trophic chain [ 3 , 4 , 5 ]. The presence of anomalous concentrations of trace metals in the environment is mainly due to anthropogenic activities, such as mining or smelting, industry, agriculture and/or traffic [ 6 , 7 , 8 , 9 ].…”

Elements in mining extracts can be potentially toxic if they are incorporated into soils, sediments or biota. Numerous approaches have been used to assess this problem, and these include sequential extractions and selective extractions. These two methods have limitations and advantages, and their combined use usually provides a rough estimate of the availability or (bio)availability of potentially toxic elements and, therefore, of their real potential as toxicants in food chains. These indirect speciation data are interesting in absolute terms, but in the work described here, this aspect was developed further by assessing the evolution of availability-related speciation in relation to the transport processes from the emission source, which are mainly fluvial- and wind-driven. This objective was achieved by characterizing tailings samples as the source of elements in soils and sediments at increasing distances to investigate the evolution of certain elements. The standard procedures employed included a sequential five-step extraction and a selective extraction with ammonium acetate. The results show that the highest percentages of Zn and Pb in tailings, soils and sediment samples are associated with oxyhydroxides, along with a significant presence of resistant mineralogical forms. In the case of Cd, its association with organic matter is the second-most important trapping mechanism in the area. The physicochemical mechanisms of transport did not transform the main mineralogical associations (oxyhydroxides and resistant mineralogical forms) along the transects, but they produced a chaotic evolution pattern for the other minor matrix associations for Zn and a decrease in exchangeable and carbonate-bound forms for Pb in soils. Interestingly, in sediments, these mobile forms showed a decrease in Zn and a chaotic evolution for Pb. The most probable reason for these observations is that Zn2+ can form smithsonite (ZnCO3) or hydrozincite (Zn5(CO3)2(OH)6), which explains the retention of a carbonate-bound form for Zn in the soil transect. In contrast, Pb and Cd can appear as different mineral phases. The order of (bio)availability was Pb > Zn > Cd in tailings but Cd > Pb > Zn in soils. The physicochemical processes involved in transport from tailings to soils produce an increase in Cd (bio)availability. The trend is a decrease in bioavailability on moving away from the source (tailings), with maximum values obtained for Cd near to the source area (200–400 m).
