“…The biogeochemical characteristics of As are not fully dependent on its total concentration in soil [ 18 , 91 ]. For instance, the portion of total As existing as a basic constituent of stable minerals in soil is generally not bioavailable [ 92 ].…”

Environmental contamination with arsenic (As) is a global environmental, agricultural and health issue due to the highly toxic and carcinogenic nature of As. Exposure of plants to As, even at very low concentration, can cause many morphological, physiological, and biochemical changes. The recent research on As in the soil-plant system indicates that As toxicity to plants varies with its speciation in plants (e.g., arsenite, As(III); arsenate, As(V)), with the type of plant species, and with other soil factors controlling As accumulation in plants. Various plant species have different mechanisms of As(III) or As(V) uptake, toxicity, and detoxification. This review briefly describes the sources and global extent of As contamination and As speciation in soil. We discuss different mechanisms responsible for As(III) and As(V) uptake, toxicity, and detoxification in plants, at physiological, biochemical, and molecular levels. This review highlights the importance of the As-induced generation of reactive oxygen species (ROS), as well as their damaging impacts on plants at biochemical, genetic, and molecular levels. The role of different enzymatic (superoxide dismutase, catalase, glutathione reductase, and ascorbate peroxidase) and non-enzymatic (salicylic acid, proline, phytochelatins, glutathione, nitric oxide, and phosphorous) substances under As(III/V) stress have been delineated via conceptual models showing As translocation and toxicity pathways in plant species. Significantly, this review addresses the current, albeit partially understood, emerging aspects on (i) As-induced physiological, biochemical, and genotoxic mechanisms and responses in plants and (ii) the roles of different molecules in modulation of As-induced toxicities in plants. We also provide insight on some important research gaps that need to be filled to advance our scientific understanding in this area of research on As in soil-plant systems.

“…It is known that some bacteria are able to adsorb trace minerals on the surface and accumulate them inside the cells [5]. In their early research, the authors addressed the ability of a complex biological preparation based on Azotobacter and Bacillus rhizobacteria to influence the phase state and migration of arsenic in the soil-plant system [6].…”

The study was aimed at the transformation of arsenic compounds in the rhizosphere, its accumulation in plants, P and Si translocation to plants under the influence of Bacillus megaterium var. phosphaticum, and Bacillus mucilaginosus with various forms of As compounds in the soil. The authors describe the maximum effect of Bacillus megaterium var. Phosphaticum strain on As migration, its mobilization and immobilization in the rhizosphere due to arsenic leaching from mineral and difficult-todestroy compounds and its accumulation in plants. The forms of arsenic compounds were isolated from the rhizosphere based on sequential extraction procedures. The features of the inter-element As-P interaction in plants were established. With the intense accumulation of As in the rhizosphere inoculated with rhizobacteria, the intake of phosphorus into plants was not observed, as contrary to Si. The study of As and biogenic elements behavior under the influence of rhizobacteria is of great importance in the development of ecobiotechnologies related to soil remediation and crop production.

“…In addition to those above, relatively harmless arsenocholine (AsC) and various arsenosugars and arsenolipids can be mentioned as examples of organic arsenic species. Plant hyperaccumulators, such as some ferns, can bind arsenic in complexes usually with phytochelatines [4,5]. More information about arsenic species can be found elsewhere, e.g., in [6].…”

Total arsenic and water-soluble arsenic species were determined in canned fish bought in Graz (n = 6) and Prague (n = 8) with inductively-coupled plasma mass spectrometry and anion-exchange liquid chromatography. A difference in total arsenic content between samples from Prague (mean 3.4; standard deviation (s.d.) 1.2 mg kg -1 ) and Graz (mean 2.5; s.d. 0.7 mg kg -1 ) was not significant, however Prague samples differed in abundance of arsenobetaine (mean 83% of extractable arsenic; s.d. 16%) vs. Graz samples (mean 66%; s.d. 10%). No differences in total arsenic were caused by fish species (mackerel, sardine, herring, tuna) and origin (Northeast and Eastern-central Atlantic).
