“…The combined application of these materials could yield eventual potential risks because organic products may dissolve Fe (oxyhydr)oxides and promote the reduction of metal(loid)s, even if good performance is achieved early in the treatment process (Lottermoser, 2010;Rakotonimaro et al, 2019). The dissolution of Fe (oxyhydr)oxides entails the concomitant release of the retained As, which can cause more adverse effects on ecosystems due to its higher toxicity if mobilized in its reduced state (Di et al, 2019).…”

“…This process is performed by microorganisms, originating monomethylated, dimethylated, and trimethylated species of As(III) (MMA(III), DMA(III), and TMA(III), respectively) and As(V) (MMA(V), DMA(V), and TMAO(V), respectively) (Mandal & Suzuki, 2002;Wang & Mulligan, 2006). The toxicity of As largely depends on its chemical form, varying according to the following sequence: MMA(III) % DMA(III) > As(III) > As(V) > MMA(V) % DMAs(V) > TMA(III) % TMAO(V) (Di et al, 2019). Its toxic forms can cause many adverse health effects to humans.…”

Arsenic and antimony are metalloids that exhibit similar geochemical behavior and are often found in the same mineral associations, co-occurring in mine waste derived from ore exploitation. Due to their adverse effects on ecosystems and human health, techniques to limit their release into the environment from mine wastes and the consequent pollution of surrounding areas are of great interest. This review addresses the geochemical behavior of these two metalloids in mining environments and presents an overview of the main strategies used to stabilize or encapsulate As-or Sb-bearing mine waste, highlighting and comparing their shortcomings and advantages. Several approaches have been investigated, including the 1) establishment of surface covers, 2) application of amendments, 3) solidification using cementing or geopolymer, and 4) application of protecting coatings. Several of these methods have exhibited potential for treating As mine waste. However, the weathering state, composition, and final fate of wastes are determining factors affecting treatment effectiveness. Regarding Sb mine waste, only cementation processes have shown some good performance. Further research effort is required to develop effective passivating coatings or stabilization methods to treat these mine wastes.

Environmental remediation by traditional physicochemical methods has several drawbacks, the most important of which is the high cost. Phytoremediation is the use of plants and associated microorganisms to improve degraded environments, Plant sensitivity to climate, seasonal growing, resistant to toxic compounds and suspended solids are limitations of this cost effective technology. Costs of phytoremediation can be offset by the production of valuable biomass for timber, fuel, essential oils and other uses. In some cases, the biomass may contain high concentrations of valuable trace elements such as nickel. Successful phytoremediation depends on suitable plants selection and application of appropriate agronomic techniques. In most cases, locally native plants are the most suitable phytoremediator for phytoremediation. This review collected 20 phytoremediation related terms containing phytomining,

“…As(III) is then rapidly incorporated into the vascular cells through symplastic intracellular transporters and rapidly accumulated in rice kernels. Recently, the study of the accumulation in plants of arsenic methylated forms produced by soil microorganisms (Lomax et al, 2012;Di et al, 2019), particularly the highly toxic dimethyl monothioarsenate (DMMTA), has raised research interest (Colina Blanco et al, 2021;Dai et al, 2021Dai et al, , 2022Zhao et al, 2021;Pischke et al, 2022).…”

Arsenic is one of the most potent carcinogens in the biosphere, jeopardizing the health of millions of people due to its entrance into the human food chain through arsenic-contaminated waters and staple crops, particularly rice. Although the mechanisms of arsenic sensing are widely known in yeast and bacteria, scientific evidence concerning arsenic sensors or components of early arsenic signaling in plants is still in its infancy. However, in recent years, we have gained understanding of the mechanisms involved in arsenic uptake and detoxification in different plant species and started to get insights into arsenic perception and signaling, which allows us to glimpse the possibility to design effective strategies to prevent arsenic accumulation in edible crops or to increase plant arsenic extraction for phytoremediation purposes. In this context, it has been recently described a mechanism according to which arsenite, the reduced form of arsenic, regulates the arsenate/phosphate transporter, consistent with the idea that arsenite functions as a selective signal that coordinates arsenate uptake with detoxification mechanisms. Additionally, several transcriptional and post-translational regulators, miRNAs and phytohormones involved in arsenic signaling and tolerance have been identified. On the other hand, studies concerning the developmental programs triggered to adapt root architecture in order to cope with arsenic toxicity are just starting to be disclosed. In this review, we compile and analyze the latest advances toward understanding how plants perceive arsenic and coordinate its acquisition with detoxification mechanisms and root developmental programs.
