“…Results suggest significant As transfer from irrigation water to rice and vegetables and subsequent body loading. This result is in consensus with the finding of Joardar et al [ 95 ], who reported As accumulation in scalp hairs of a number of arsenicosis patients due to As-contaminated rice and vegetables consumption, although the accumulation pattern was diverse.…”

“…Comparable patterns of arsenic uptake in plants cultivated in regions with high soil concentrations of As and irrigated by arsenic-rich groundwater have been discovered [ 92 , 93 ]. One of the most important methods for calculating the rate of chronic As exposure is to evaluate the amount of As in scalp hair [ 94 , 95 ]. As is commonly found in hair at background levels of 0.08–0.250 mg/kg [ 96 ], 1 mg As per kg hair has been unanimously established as the toxicity indicator [ 96 , 97 , 98 ].…”

Arsenic (As) in groundwater and its accumulation in agricultural produces has caused serious threats to human health. The majority of current research on As mainly focuses on the technical aspects while bypassing the social perspectives. Farmers are the prime stakeholders as well as executors of agricultural strategies, and their adaptation largely depends on how they perceive the risk for which a mitigation strategy is proposed. This study aims to explore how rice and vegetable farmers perceive As accumulation in their rice and vegetables as well as explore current crop- and body-loading status, the subsequent health consequences of As, and alleviation possibilities with mitigation strategies and to investigate if there is an association between their socioeconomic status and their level of perception. Results reveal that one-fourth of the farmers gave a positive message regarding the As-contamination scenario in rice and vegetables. Although 10 farmers’ socioeconomic characteristics were positively significant, distinctive emphasis should be given to five predictor variables explaining 88% variances: knowledge, direct participation in farming, information sources used, participant education, and organizational participation. Path analysis depicts that direct participation in farming presents the highest positive total effect (0.855) and direct effect (0.503), whereas information sources show the highest positive indirect effect (0.624). The mean As content in all five locations was statistically significant at the 5%, 5%, 0.1%, 1%, and 1% probability levels in scalp hairs, rice, vegetables, soils, and irrigation water, respectively. The first principal component (PC1) explains 92.5% of the variation. Significant variations were primarily explained by As levels in irrigation water, rice grain, and soil. Farmers’ perception is far behind the actual field status of As level and its transfer. Therefore, intensified priorities should be administered on the farmers’ characteristics contributing to variances in perception. The findings can be utilized for policy formulation in all As-endemic nations. More multidisciplinary research can be undertaken on farmers’ attitude towards adopting As-mitigation techniques, with a focus on the socioeconomic position found to influence farmers’ perceptions.

“…The estimation of As concentration in the stool were performed using the digestion facility and HG-AAS instrument available at School of Environmental Studies, Jadavpur University. The description of HG-AAS instrument and the sample preparation and methodology for As analysis has been detailed in earlier publications (Das et al, 2021a;Joardar et al, 2022).…”

Geogenic groundwater arsenic (As) contamination is a persistent health threat in the district of Nadia, West Bengal India. Despite provision of safe piped water, local populations in these areas are still exposed to As through diet as the cultivation is majorly dependent on As contaminated shallow groundwater causing significant As accumulation in agricultural foodstuffs. Although urine is an established biomarker for As exposure through drinking water yet, it does not reflect the actual exposure through diet. Hence, stool-As concentration of exposed population should be evaluated to assess the true exposure through diet. The present case-control study evaluates As concentration in stool samples of exposed (n = 24) and unexposed (n = 36) populations. Average stool-As concentration found was 234 ± 207 µg/kg in exposed population while only 66 ± 22 µg/kg in control samples; comparable to those of urine samples of case and control; respectively. Positive Pearson correlation and a significant difference of variance through ANOVA (p = 0.01; Fcrit= 1.65) among stool-As, urine-As, groundwater-As, age and BMI found for case samples indicate that stool also presents comparable and measurable As concentrations upon exposure. Mann-Whitney U test confirms that random values of stool-As in case samples varied significantly (p < 0.001) than those of control samples. Besides, multi-metal analysis of stool digest indicated that stool-As correlated negatively with most of the metals in case and positively with control samples. These observations along with ease of collection and detection due to higher concentration in the matrix, suggest that stool may act as a decisive biomarker of As exposure through diet. To the best of our knowledge, this is a pioneering study to establish stool as a reliable and significant biomarker for assessing As exposure as limited investigations exist focused on human faecal samples on long term naturally exposed adult human population.
