“…In addition to causing adverse non-carcinogenic health effects, Cd and Cr are categorized as carcinogenic substances [ 66 ]. Previous studies showed that HQ values were usually higher for children than for adults [ 45 , 46 , 67 ]. One of the main reasons for the high non-carcinogenic risk in children is their lower body weight (BW) compared to adults [ 68 ].…”

“…The health risk posed by exposure to the PTMs comprising Cd, Cr, Cu, Mn, and Ni in the leaching solution through drinking water ingestion was quantified using the hazard quotient (HQ) method of the USEPA (1999) [ 43 ]:

where CDI is the dose of metal intake (mg/kg/day) and R f D is the reference dose (mg/kg/day), which refers to the maximum acceptable dose of a toxic substance. The R f D values of Cd, Cr, Cu, Mn, and Ni for exposure through drinking water ingestion were 0.0005, 0.003, 0.037, 0.14, and 0.02 mg/kg/day, respectively [ 44 , 45 ]. IR is the ingestion rate of water, which was set to 3.49 L/day for adults [ 45 ], and BW is body weight, which was taken as 70 kg for adults [ 46 ].…”

To investigate the leaching characteristics and potential environmental effects of potentially toxic metals (PTMs) from alum mine tailings in Lujiang, Anhui Province, soaking tests and simulated rainfall leaching experiments were conducted for two types of slag. PTMs comprising Cd, Cr, Cu, Mn, and Ni were detected in the slag. Cu and Cd contents exceeded the national soil risk screening values (GB 15618-2018). pH values of the two slag soaking solutions were negatively correlated with the solid:liquid ratio. pH values of the sintered slag soaking solutions with different solid:liquid ratios finally stabilized between 4.4 and 4.59, and those of the waste slag soaking solutions finally stabilized between 2.7 and 3.4. The concentrations of Cd, Cr, Cu, Mn, and Ni leached from waste slag were higher than those from sintered slag, and the dissolved concentrations of these PTMs in sintered slag were higher under rainfall leaching conditions than soaking conditions (the difference in Cr concentration was the smallest, 5.6%). The cumulative release of Cd, Cr, Cu, Mn, and Ni increased as the leaching liquid volume increased. The kinetic characteristics of the cumulative release of the five PTMs were best fitted by a double constant equation (R2 > 0.98 for all fits). Single factor index evaluations showed that Mn and Ni were the PTMs with high pollution degrees (Pi for Mn and Ni exceed 1) in the leaching solutions. However, considering the biotoxicity of PTMs, the water quality index evaluations showed that the water quality of the sintered slag soaking solution, the waste slag soaking solution, and the sintered slag leachate was good, poor, and undrinkable, respectively. The health risk assessment showed that the total non-carcinogenic risk (HI) values in adults for both the sintered slag leachate and waste slag soaking solution exceeded the safe level of 1, with HI values of 3.965 and 2.342, respectively. The hazard quotient (HQ) for Cd was 1.994 for the sintered slag leachate, and Cd and Cr make up 50.29% and 15.93% of the total risk, respectively. Cr makes up 28.38% of the total risk for the waste slag soaking solution. These results indicate a high non-carcinogenic risk of exposure to Cd and Cr in the leaching solution used for drinking purposes. These findings may provide a reference for the evaluation and ecological control of PTM pollution in alum mining areas.

“…However, the issue of water remains a crucial one, as supplying cities with drinking water has always been a top priority and covers several aspects viz-viz economic, environmental, technical, political, and socio-cultural (Mwanza et al, 2019). In some regions of the world, groundwater is the only drinking water resource for human population; it is dependent on a combination of natural and anthropogenic factors (Joodavi et al, 2021). Groundwater is generally of good quality because it is better protected, but this quality can deteriorate due to inadequate protection and poor resource management (Sadiya et al, 2018).…”

The shortages in the distribution of drinking water from the public network in the municipality of Jacqueville lead the population of the peri-urban villages of the said municipality to turn to well water, the quality of which remains a concern. The objective of this study is to evaluate the hygienic quality of well water used by the population for their domestic needs. The measurement and sampling were carried out on eleven wells in three peripheral villages of the commune. The analysis covered ten physico-chemical parameters (T, pH, EC, Turbidity, salinity, NO 3 , NO 2 , NH 4 , PO 4 and SO 4 ) and three microbiological parameters (total coliforms, Escherichia coli and faecal streptococci). Principal component analysis (PCA) was applied to the data to highlight the phenomena causing the degradation of the water. The calculation of the fecal contamination index (FCI) revealed three classes of water quality: Uncontaminated wells, moderately contaminated wells, and heavily contaminated wells. The study of the general quality shows that most of the wells studied had warm, turbid water with a high population of pathogenic microorganisms. This study highlighted the health risk incurred by the population when consuming the water from these wells without prior treatment.
