“…Interestingly, the cancer risk for oral ingestion was consistently higher than that for skin absorption in both the dry and rainy seasons in both groups. Thus, the oral route was the most common risk factor for cancer, and the results of this study were consistent with other studies [77] , [82] , [83] .…”

“…In this study, the hazard quotient findings indicated that the oral ingestion route had higher HQ values than the dermal route. Therefore, the ingestion route was the predominant route for noncancer risks, and the results of this study were consistent with other studies conducted in China and Pakistan [82] , [83] , [85] . Similar to the carcinogenic risk, the cumulative noncarcinogenic risk of arsenic for children for combined exposure routes is significantly higher than that for adults.…”

“…However, the oral and dermal contact intake effects the most but all the effects can be neglected when compared to the effect of oral intake. Therefore, exposure to trace elements is measured mainly in two ways: oral (ingestion) and dermal (absorption) (Ehsan et al., 2020). USEPA (2005) recommended a lifelong average daily dose as an exposure measure to estimate a person's daily exposure as also suggested by (Varol & Davraz, 2016).…”

Several million tons of coal are extracted which discharge the contaminated mineral water into the environment in the coal mines located in the Korba basin (Chhattisgarh, India) chosen as the study area. The aim of this work is to describe: (i) the physico‐chemical characteristics (pH, EC, TDS, DO, RP, CC (carbonate carbon), OC (organic carbon) F−, Cl−, NO3−, SO42−, SiO44−, PO43−, Na+, K+, Mg2+, Ca2+, Al, As, Sb, Fe, Mn, Zn, Cd, Pb, and Hg) of the coal mine water samples, (ii) spatial, seasonal (i.e. PrM (pre‐monsoon), M (monsoon) and PtM (post monsoon) and temporal (over the period of 2012–2017) variations, (iii) sources of contaminants from fourteen coal mines, (iv) suitability of the water for drinking and other uses, and (v) health impact of the mine water in view of developing remedial approaches.The mine water is neutral in nature with high TDS (total dissolved solid) values ranging from 620 to 13711 mg L−1 due to mainly high carbon content. The concertation of all species lies between 519–11432 mg L−1 with maximum value of OC. The most dominating species were OC, CC, Cl−, NO3−, SO42−, Na, and Ca. Species, that is, F−, OC, Al, Fe, As, Sb, Cd, Pb, and Hg occurred beyond their limits. Their higher concentration in the PtM is observed. Water quality index (WQI) values ranged from 17.52 to 95.68 in the PtM period. 42.85%, 21.42%, and 7.14% of water samples represent “excellent water”, “good water” and “poor water” respectively in the PtM period. In addition, the fertilizer and trace element concentrations in the water samples were compared with the limit values determined for usability as drinking water. Accordingly, it was concluded that it is not suitable for use as drinking water in terms of TDS, F−, and NO3− concentrations. In addition, AsT (total arsenic), F− and NO3− pollutants were detected in the water samples, and it was observed that F− and NO3− ions did not have a carcinogenic effect. A health risk assessment of As has been made, and it is found that adults and children have a low risk of developing cancer from the exposure. However, arsenic has high non‐carcinogenic and potentially harmful effects.

“…An adoption of the health risk assessment model for the water environment was proposed by the USEPA [77]. Exposure to As in drinking water is mainly via both drinking water and skin contact [78]. The equations for long-term average daily exposure to groundwater for both exposure routes are given in Equations ( 1) and ( 2):…”

The presence of high concentrations of geogenic arsenic (As) in groundwater poses a serious threat to the health of millions of individuals globally. This paper examines the research progress of groundwater with high concentrations of geogenic As through a comprehensive literature review and analysis, covering distribution, health risks, in situ remediation, regulatory technologies, and development trends, to establish a reference for future research. The global distribution of geogenic high-As groundwater is mainly in inland basins and river deltas of countries in South Asia, East Asia, and South America. High-As risk areas can be modeled using hydrogeologic data and field measurements. This modeling approach allows for assessing and measuring potential areas of high-As groundwater. In order to provide safe drinking water promptly and effectively to areas affected by high-As groundwater, in situ rapid detection and remediation techniques have been given significant attention. This paper introduces household- or community-scale As removal technologies, including flocculant–disinfectant, bucket treatment units, use of activated alumina, use of nano zero-valent iron, aquifer iron coating technology, and bioremediation, summarizing the basic mechanisms of arsenic removal for each technology. Guaranteeing the sustainability of site-scale remediation technologies, reasonable aquifer management, and exploring alternative water sources are crucial for combating high-As groundwater contamination. Future studies should aim to elucidate the mechanisms of As’s coexistence with other pollutants in groundwater, effectively treating As-containing wastes or sludge produced during the treatment process and exploring better treatment options.
