“…Many studies reported that prolong exposure of high level of arsenic in drinking water causes arsenicosis with various health complications such as skin lesions and cancer. Recently, scientists have been explored the possible therapy to lessen the arsenic toxicity in the community such as techniques of arsenic removal from water [ 17 , 18 ] and investigation of therapeutic candidate compound for arsenic-induced DNA damage [ 19 , 20 ]. Retrospective studies reported that arsenic-contaminated drinking water exposure during perinatal period showed impairment of cognitive abilities in the childhood [ 21 , 22 ].…”

Background Arsenic is a harmful heavy metal and a well-known developmental neurotoxicant. Previously, we have reported that gestational arsenic exposure resulted in impaired social behaviors in F1 and F2 male mice. However, little is known about the developmental arsenic exposure on anxiety-like behavior. This study aimed to detect the effect of gestational arsenic exposure on anxiety-like behavior and related gene expressions in 74-week-old F1 female mice. Method Pregnant C3H/HeN mice (F0) were given drinking water containing 85 ppm sodium arsenite (NaAsO 2 ) from gestational day 8 to 18. The control mice were given tap water only. At 74-week-old, open field test was performed, then anxiety and apoptosis-related factors were determined by real_time RT_PCR and immunohistochemical analyses. Results The arsenite-exposed F1 female mice showed decreased center entry and center time in open field test. In addition, the number of grooming and fecal pallet was significantly increased in the arsenite-exposed F1 female mice compared to the control. Downregulation of brain-derived neurotrophic factor (BDNF), serotonin receptor (5HT1A) and upregulation of nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB), interleukin 1 β (IL-1β), cyclooxygenase 2 (COX2), caspase-3, Bcl2-associated X protein (Bax) were detected in the prefrontal cortex in the arsenite-exposed F1 female mice. Microglial marker ionized calcium-binding adapter molecule 1 (Iba1)-positive cells were increased in the arsenite-exposed F1 female mice. Moreover, a significantly increased plasma corticosterone level was observed in the arsenic-exposed F1 female mice. Conclusions This study suggested that gestational arsenic exposure induced anxiety-like behavior accompanied with dysregulation of neurological and immunological markers, neuroinflammatory responses, neuronal apoptosis, and decreased neurogenesis in the prefrontal cortex of F1 female mice.

“…In order to achieve the above targets, As removal from the water environment is an urgent requirement in the contaminated areas. Recently, various techniques have been developed and applied to remove As, and these include ion exchange [5], oxidation [6], coagulation-flocculation [4], phytoremediation, membrane filtration [7], and adsorption [8]. However, the development of these technologies and their application to groundwater systems in low-and middle-income countries remains a significant challenge for researchers, manufacturers, and policymakers.…”

Groundwater contamination by arsenic (As) is a serious issue in many countries, particularly in middle- and low-income nations. High concentrations of As in drinking water and groundwater cause serious health problems. Numerous technologies, such as ion exchange, oxidation, coagulation–flocculation, phytoremediation, membrane filtration, and adsorption, have been applied to remove As from the water environment. Among these technologies, adsorption is the preferred method in low- and middle-income countries due to its affordability, high efficiency, and ease of design, operation, and maintenance. Along with this technology, a variety of materials have been developed and investigated for their ability to remove As from water environments, though iron-based adsorbents have been reported to be the most effective. Thus, the aim of this paper is to briefly review the sources of As and the prevalence of As species in water bodies, as well as the currently available technologies for As removal. A detailed analysis of recent studies on iron-based adsorbents used to remove As from aqueous solutions in both laboratory conditions and field conditions is presented.
