Where; CD Iing and CD der represent the chronic daily intake via drinking and skin absorption (mg/kg/day), respectively. CW is As concentration (μg/L); IR is the average daily water consumption (L/day) (2 liter/day for adults; 1 liter/day for children); the EF corrospondes to the frequency of exposure (365 days/year); ED is the duration of exposure (70 years for adults and 10 years for children); BW refers to average body weight (15 kg for children; 70 kg for adults); AT is the averaging duration (365 days/year x 70 years for an adult; 365, days/year x 10 years for a child); SA is the surface area of the skin exposed to water (18,000 cm 2 for adults; 6600 cm 2 for children); Kp is the dermal permeability coefficient in water (cm/h) and 0.001 for As; ET is the exposure time (0.58 h/day for adults; 1 h/day for children) and CF is the unit conversion factor (0.001 L/cm 3 ) [5] , [41] , [52] , [53] , [54] , [55] , [56] ( Table 1 ).…”

Purpose: Heavy metals are among the commonest cause of water pollution and impact human health worldwide. Therefore, this study aims to assess the probable health risk (non-carcinogenic and carcinogenic risk) for adults and children that are exposed to toxic heavy metals (Cu, Pb, Cd, Cr, Zn and Ni) through ingestion and dermal contact with dug well water in the locations. Methodology: The hand dug wells serve as sources of drinking water, domestic and industrial purposes. In this study, composite samples from the locations were tested for the presence of heavy metals using Atomic Absorption Spectrophotometer (AAS). The health risk assessments were evaluated. Findings: The results of the HQ values of heavy metals for combined pathways were below the safety level (HQ < 1) for adults, while the HI for children were higher than the safety limit in some stations. The average values of total carcinogenic risk index (CRI) through exposure to drinking water for children and adults were lower than 10−6. Overall, the CRI total through exposure to drinking water for children and adults are within safety level of WHO risk, negating the probability of carcinogenic risk for the children and adults to the carcinogenic elements via ingestion and dermal routes. Recommendation: Appropriate purification, improvement in enlightenment programs and control measures should be implemented to protect the health of the residents in these localities.

“…The health risk assessment was done for ingestion and dermal contact exposure to PTEs in groundwater (USEPA, 1989; USEPA, 2011) using Eqs 1-5. Parameters and input assumptions for exposure assessment to PTEs through ingestion and dermal pathways were obtained from literature (USEPA, 2011; Walpole et al, 2012;Al-Hwaiti et al, 2018;Haque et al, 2018;Mohammadi et al, 2019) (Table 2). The studied local group were adults and children.…”

Groundwater from shallow hand-dug wells at an abandoned gold mine tailings dam was characterised for selected physicochemical parameters during dry and wet seasons of 2018 and 2019. Health risk exposure of the local population (adults and children) through ingestion and dermal exposure was assessed. Groundwater quality parameters were lower than international drinking water quality guidelines (p < 0.05). The parameters were significantly influenced by season of the year (As, Cl−, SO42−), nature (As, Cd, Cl−, Fe, NO3−, SO42−), depth (Cd, Cl−, Fe, Ni, SO42−) and direction of the well (Cu, Cl−, Fe, NO3−, Pb, SO42−) (p < 0.05) relative to the tailings dam. Groundwater did not pose non-carcinogenic risk due to studied trace elements. However, arsenic had the potential to cause medium to high cancer risk to the local population. We propose re-vegetation of the tailings dam, diversion of surface tailings drainage to a containment pond and the provision of continuous piped water supplies.
