“…The As speciation and plant availability in the paddy soil environment is controlled by different biotic and abiotic factors [3]. However, the biogeochemical behavior of As in paddy soil-rice systems makes it easily available for plant uptake and subsequent accumulation in rice grains [64,65]. Several studies in rural areas contaminated with As, located all over the word, indicate that As accumulates in some parts of the rice plants, such as the roots, shoot, rice husk, and in the rice grains [66][67][68], and As accumulation in paddy roots was 28-and 75-fold higher than in shoots and rice grains, respectively [66].…”

“…In any case, it is clear that As contamination on rice agroecosystems produces many adverse effects in humans [71], animals, plants, and soil microbiota [72]. At present, several mitigation strategies are being developed, applying diverse technological/biotechnological approaches in order to reduce this serious global health risk [64,69].…”

Arsenic (As) is quite an abundant metalloid, with ancient origin and ubiquitous distribution, which represents a severe environmental risk and a global problem for public health. Microbial exposure to As compounds in the environment has happened since the beginning of time. Selective pressure has induced the evolution of various genetic systems conferring useful capacities in many microorganisms to detoxify and even use arsenic, as an energy source. This review summarizes the microbial impact of the As biogeochemical cycle. Moreover, the poorly known adverse effects of this element on eukaryotic microbes, as well as the As uptake and detoxification mechanisms developed by yeast and protists, are discussed. Finally, an outlook of As microbial remediation makes evident the knowledge gaps and the necessity of new approaches to mitigate this environmental challenge.

“…are required in trace amounts ( Karthika et al, 2018 ; Hasanuzzaman et al, 2020a ), and can be toxic when taken up in excess by the plants ( Pandey et al, 2019 ; Hasanuzzaman et al, 2020a ). Besides, other non-essential metals/metalloid elements, like arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), are toxic to plant even at low amounts ( Asati et al, 2016 ; Mawia et al, 2020 ; Raza et al, 2021a ). The toxicity of non-essential toxic metals/metalloids in plants can lead to severe damages, including reduced or inhibited growth, low biomass and reduced production, chlorosis, water and nutrient imbalance, denaturation of essential enzymes and proteins, production of reactive oxygen species (ROS), disturbed electron transport chain, lipid peroxidation, and at times ultimately plant death ( Rucińska-Sobkowiak, 2016 ; Venkatachalam et al, 2017 ; Jalmi et al, 2018 ; Tiwari and Lata, 2018 ; Gashi et al, 2020 ; Salehi et al, 2021 ).…”

Food safety has emerged as a high-urgency matter for sustainable agricultural production. Toxic metal contamination of soil and water significantly affects agricultural productivity, which is further aggravated by extreme anthropogenic activities and modern agricultural practices, leaving food safety and human health at risk. In addition to reducing crop production, increased metals/metalloids toxicity also disturbs plants’ demand and supply equilibrium. Counterbalancing toxic metals/metalloids toxicity demands a better understanding of the complex mechanisms at physiological, biochemical, molecular, cellular, and plant level that may result in increased crop productivity. Consequently, plants have established different internal defense mechanisms to cope with the adverse effects of toxic metals/metalloids. Nevertheless, these internal defense mechanisms are not adequate to overwhelm the metals/metalloids toxicity. Plants produce several secondary messengers to trigger cell signaling, activating the numerous transcriptional responses correlated with plant defense. Therefore, the recent advances in omics approaches such as genomics, transcriptomics, proteomics, metabolomics, ionomics, miRNAomics, and phenomics have enabled the characterization of molecular regulators associated with toxic metal tolerance, which can be deployed for developing toxic metal tolerant plants. This review highlights various response strategies adopted by plants to tolerate toxic metals/metalloids toxicity, including physiological, biochemical, and molecular responses. A seven-(omics)-based design is summarized with scientific clues to reveal the stress-responsive genes, proteins, metabolites, miRNAs, trace elements, stress-inducible phenotypes, and metabolic pathways that could potentially help plants to cope up with metals/metalloids toxicity in the face of fluctuating environmental conditions. Finally, some bottlenecks and future directions have also been highlighted, which could enable sustainable agricultural production.

“…According to the 2014 National Soil Pollution Survey Bulletin, the total exceedance rate of Cd in the soil is 16.1%, of which the highest exceedance rate is 7%, and the exceedance values are tens or even hundreds of times higher than the environmental background value [ 29 ]. The world has been exposed to high concentrations of As for a long time [ 30 ]. There are more than 10,000 As-contaminated sites in Australia [ 31 ].…”

Cadmium (Cd) and arsenic (As) are widely distributed pollutants that co-exist in the environment; however, their joint toxicity on living organisms is still largely unknown. In this study, we explored the joint toxicity of concurrent exposure to Cd and different As species at low concentrations on Caenorhabditis elegans (C. elegans) in comparison to single exposures. Endpoints such as germ cell apoptosis, the number of oocytes, brood size, and the life span were employed to evaluate the combined effects of Cd and As on exposed C. elegans from L3 or L4 stages. Our results showed that concurrent exposure to non-toxic concentrations of Cd and As caused the synergy of reproductive and developmental toxicity. The presence of Cd promoted the accumulation of As in both germline and intestine detected by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Although a conversion of As(III) to As(V) was detected as dependent on pH according to the microenvironment of the intestine in the worm, there was no significant difference of toxicity in C. elegans concurrently exposed to Cd and different As species. Using loss-of-function mutant strains, As was deemed responsible for the enhanced joint toxicity, and in which gcs-1 played a key protective role. These data help to better evaluate the comprehensive adverse effects of concurrent exposure of heavy metals at low concentrations on living organisms in the environment.
