“…The groups were as follows: Group I (control group, received arsenic-free water), Group II (received 5 ppm arsenic in drinking water), Group III (received 300 ppm arsenic in drinking water), Group IV (received drinking water with SNEC30 alone), Group V (received 5 ppm of arsenic + SNEC30) and Group VI (received 300 ppm of arsenic + SNEC30). The doses of NaAsO 2 selected were based on previously published studies [ 31 , 32 ] and the optimal concentration found in ground water (5 ppm) of South and Southeast Asian Belt including India, Bangladesh, Nepal, Vietnam and China [ 33 ]. An acute lethal dose, i.e., 300 ppm, was selected keeping in mind the accidental ingestion of insecticides or pesticides and exposures that usually occur to miners, smelters, among others [ 33 ].…”

“…Several studies have been conducted on groundwater arsenic contamination in Bangladesh and neighboring West Bengal of India (Acharyya et al 2000;Ravenscroft et al 2001;UNICEF 2001;Chakraborti et al 2010;CSISA-MI 2015;MICS-B 2018;World Bank Group 2019). Numerous studies, not only in Bangladesh but also in other Asian countries, have been conducted, including China (Sun 2004;Jiang et al 2019;Sanjrani et al 2019), India (Paul et al 2015;Chandrashekhar et al 2016;Shaji et al 2020;Alsubih et al 2021), Vietnam (Glodowska et al 2020), and Japan (Hossain et al 2016;Vongphuthone et al 2017), where arsenic contamination in the environment reached an alarming position. However, the results have not produced the mitigation of arsenic poisoning.…”

Arsenic contamination of alluvial aquifers of the Bengal delta plain causes a serious threat to human health for over 75 million people. The study aimed to explore the impacts of chemical fertilizer on arsenic mobilization in the sedimentary deposition of the alluvial Bengal delta plain. It selected ten comparatively higher affected Districts and the least affected two Divisions as a referral study site. The countrywide pooled concentration of arsenic in groundwater was 109.75 μg/L (52.59, 166.91) at a 95% confidence interval, which was double the national guideline value (50 μg/L). The analysis results showed a strong positive correlation (r ≥ 0.5) of arsenic with NO3, NH4, PO4, SO4, Ca, and K, where a portion of those species originated from fertilizer leaching into groundwater. The results showed that PO4 played a significant influence in arsenic mobilization, but the role of NO3, SO4, and NH4 was not clear at certain lithological conditions. It also showed that clay, peat, silt-clay, and rich microbial community with sufficiently organic carbon loaded soils could lead to an increase in arsenic mobilization. Finally, the study observed that the overall lithological conditions are the main reason for the high arsenic load in the study area.

“…The main source of human exposure to iAs is through contaminated drinking water and the maximum allowed limit established by the World Health Organization for iAs in drinking water is 10 µg/l (1). However, an estimated 500 million individuals worldwide still are exposed to high concentrations of iAs, ranging from 400 to 25,000 µg/l (2). Chronic exposure to iAs through contaminated drinking water may lead to non-malignant disorders and to various types of cancer, including bladder, prostate, lung and skin (3).…”

Chronic exposure to inorganic arsenic (iAs) through contaminated drinking water is an important health problem in certain countries. The use of phytochemicals such as curcumin has recently emerged as an alternative strategy for preventing cellular damage caused by iAs. The Epstein-Barr virus (EBV) affects ~90% of the population and experimental evidence suggested that curcumin mediates cytotoxicity against EBV-infected cells. Due to the potential for an interaction of these factors, the aim of the present study was to evaluate the effect of this phytochemical on iAs-related toxicity in EBV-infected cells. Two independent EBV-immortalized human lymphoblastoid cell lines (LCLs) were used as the model. The cell lines were first incubated with increasing concentrations of curcumin or iAs for 24 and 15 h, respectively, to determine the individual effects of each exposure on cell death. In the next experiment, cell cultures were pre-incubated with 5 µM curcumin for 9 h prior to treatment with 10 µM iAs for 15 h, followed by evaluation of cell death and the cell cycle profile via flow cytometry. The results indicated that individual treatment with either curcumin or iAs induced cell death in a concentration-dependent manner. Furthermore, curcumin pre-treatment enhanced iAs-induced cell death and promoted cell cycle arrest in G1 phase. Taken together, these results suggested that curcumin sensitizes EBV-positive LCLs to the cytotoxic effects of iAs.
