“…The inorganic arsenic is highly toxic (Rahaman et al, 2008). In high concentrations, arsenic poisoning can also lead to an acute condition called arsenicosis (Hering et al, 1997;Gregor, 2001;Saha et al, 1999).…”

“…The high concentrations of specific metals in the environment may be responsible for the high concentrations of these metals in the blood, urine and hair. Since arsenic toxicity is a proven factor of skin cancer, lung cancer and bladder cancer [18] and this metal is highly prevalent in the groundwater of West Bengal [19] at a concentration above 50 µg/L (recommended by World Health Organization; Erstwhile), we are trying to focus on its effect over the occurrence of oral malignancy, the latter being on an increasing level in this zone.…”

Objective: The aim is to find out any possible correlation between HPV infection and oral carcinoma along with this metal toxicity. Methods:Ethical clearance for this study was obtained from the Ethics Committee of Vivekananda Institute of Medical Sciences, Ramakrishna Mission Seva Pratishthan. Patients attending our hospital were screened for the presence of oral premalignant and malignant lesions. The subjects were administered a standard questionnaire. The buccal swab and hair samples (107 cases and 50 controls) were collected after obtaining informed consent from all the corresponding subjects, and were analysed for detection of HPV 16 DNA and arsenic level analysis, respectively.Results: 22.5% of malignant samples showed the presence of HPV 16 DNA. 80% of cases showed their arsenic count above the safe limit (0.8 µg/g). Conclusion:A considerable percentage of malignant samples showed the presence of HPV16 DNA, indicating that there may be a correlation between HPV infection and oral malignancy in this population. A higher percentage of cases showing an elevated arsenic count states a possible link between arsenic toxicity and the development of this disease. However, a higher population size and statistical analysis are required for a proper conclusion.

“…Arsenic poisoning is more commonplace in continents from Southeast Asia, such as Bangladesh, Vietnam, and India [47][48][49][50]. Negative health impacts caused by As include respiratory issues, cardiovascular disease, diabetes, and skin and lungs cancers, and As poisoning is potentially fatal [51][52][53][54]. As can exist in a range of oxidation states, depending on the environmental systems.…”

Density Functional Theory Study of Arsenate Adsorption onto Alumina Surfaces

Atomistic modeling of mineral-water interfaces offers a way of confirming (or refuting) experimental information about structure and reactivity. Molecular-level understanding, such as orbital-based descriptions of bonding, can be developed from charge density and electronic structure analysis. First-principles calculations can be used to identify weaknesses in empirical models. This provides direction on how to propose more robust representations of systems of increasing size that accurately represent the underlying physical factors governing reactivity. In this study, inner-sphere complex geometries of arsenate on hydrated alumina surfaces are modeled at the density functional theory (DFT)-continuum solvent level. According to experimental studies, arsenate binds to alumina surfaces in a bidentate binuclear (BB) fashion. While the DFT calculations support the preference of the BB configuration, the optimized geometries show distortion from the ideal tetrahedral geometry of the arsenic atom. This finding suggests that steric factors, and not just coordination arguments, influences reactivity. The O surf -As-O surf angle for the more favorable arsenate configurations is closest to the ideal tetrahedral angle of 109.5 • . Comparing the results of arsenate adsorption using a small cluster model with a periodic slab model, we report that the two model geometries yield results that differ qualitatively and quantitatively. This relates the steric factors and rigidity of the surface models.
