“…Arsenic is a strong reducing agent and interacts with other molecules such as sulphur, chloride and oxygen. It’s interactions with carbon containing molecules results in the formation of organic arsenic [ 15 ]. In addition, binding of arsenic with certain metals and charged ions such as Ca or Mg promotes the adsorption of As(V) in the solid particulate phases [ 16 ].…”

Arsenic is a key environmental toxicant having significant impacts on human health. Millions of people in developing countries such as Bangladesh, Mexico, Taiwan, and India are affected by arsenic contamination through groundwater. Environmental contamination of arsenic leads to leads to various types of cancers, coronary and neurological ailments in human. There are several sources of arsenic exposure such as drinking water, diet, wood preservatives, smoking, air and cosmetics, while, drinking water is the most explored route. Inorganic arsenic exhibits higher levels of toxicity compared its organic forms. Exposure to inorganic arsenic is known to cause major neurological effects such as cytotoxicity, chromosomal aberration, damage to cellular DNA and genotoxicity. On the other hand, long-term exposure to arsenic may cause neurobehavioral effects in the juvenile stage, which may have detrimental effects in the later stages of life. Thus, it is important to understand the toxicology and underlying molecular mechanism of arsenic which will help to mitigate its detrimental effects. The present review focuses on the epidemiology, and the toxic mechanisms responsible for arsenic induced neurobehavioral diseases, including strategies for its management from water, community and household premises. The review also provides a critical analysis of epigenetic and transgenerational modifications, mitochondrial oxidative stress, molecular mechanisms of arsenic-induced oxidative stress, and neuronal dysfunction.

“…Oxydiacetato (O-(CH 2 -COO − ) 2 , oda 2− ) is a versatile tridentate ligand that bears five donor oxygen atoms and forms a wide variety of mononuclear and polynuclear complexes with both d and f transition metal ions. [1][2][3] The flexible tridentate O-donor motif, formed by the simultaneous coordination of one ether and two carboxylate groups, makes this ligand especially suited for Ln, i.e., lanthanide and yttrium ions, affording the stable nine-coordinated anionic unit [Ln(oda) 3 ] 3− . 2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17] This building block has also been extensively used as a synthon to prepare heteronuclear complexes.…”

“…The synthesis and structural characterization of these heteronuclear compounds has been expanded to all lanthanide ions and Y and to various +2 metal ions. 2, Interestingly, this large family of heteronuclear compounds comprises two structural motifs with slight differences, which are attributed to the geometry of the carboxylate bridge that connects [Ln(oda) 3 ] 3− to M(II) cations. If a μ-syn-anti carboxylate bridge is formed, a porous hexagonal structure belonging to the P6/mcc space group is obtained.…”

In grassland systems of the semi-arid mining area, migration, accumulation and bioavailability of potentially toxic elements (PTEs) are important ecological and health risk issues. 38 pairs of topsoil (0-20 cm) and plant samples were collected around Baiyin city and in Dongdagou stream valley to investigate the migration of PTEs in soils, transfer of PTEs in soil-plant (shrub and herbage) systems and assess the risk in soils and plants. The total concentrations of PTE (Hg, As, Cu, Zn, Cd and Pb) were analyzed following digestion in mixture acid solution and bioavailable PTE was extracted with a strong chelating agent (DTPA-TEA-CaCl 2 ). The transfer factor (TF) and bioaccumulation factor (BCF) were calculated to examine the migration of PTEs in soil-plant. Hazard quotient (HQ) and total hazard index (THI) were calculated to assess the risk and migration of PTEs in soils. The results showed that PTEs in soils and plants of study area exceeded the soil background value and Hygienic Standard for Feeds. Correlation among the total Hg, As, Cu, Zn, Cd and Pb in soils of Dongdagou stream valley were signi cant at p < 0.01. A good correlation was exhibited between PTEs in root/aboveground parts of plants and DTPA-soil extractable. Difference of TF and BCF were existed between Dongdagou stream valley and around Baiyin city. Hg, Cu, Zn, Cd and Pb were mainly accumulated in soils near the mining area. The calculated THI was exceeded 1, and As and Pb were the major risk factors. The ability to absorb and transfer Hg, As, Cu and Pb of plants was lower in more serious polluted area. As had a stronger migration capacity in study area.PTEs in soils had an adverse health effect for residents and PTEs in plants may cause toxicity to cattle and sheep.
