Abstract Due to water shortages and the potential impact of Ethiopia’s new dam on Nile River, Egypt is seeking resources. This study assesses drinking quality associated risks from potentially toxic elements (PTEs) in Quaternary aquifer (QA) Beni-Suef, Egypt. Using a comprehensive approach, including PHREEQC geochemical modeling, ionic ratios, multivariate statistical analyses, integrated weight index (WQI), evaluated sources ion contamination mixing with QA. Various indices, such as Heavy Metal Pollution Index (HPI), ecological Risk (RI), Hazard Quotient (HQ), (HI), were used assess health risks. Monte Carlo simulations provided probabilistic assessments non-carcinogenic for adults children. GIS tools map risk identifying most deteriorated locations sustainable management. The hydrochemical analysis revealed facies Na–Cl, Ca–Mg–HCO 3 , mixed types, influenced by carbonate dissolution, exchange, silicate weathering. Contamination sources, particularly north south, linked agricultural activities, irrigation return flow, municipal waste, evaporation. WQI indicated that 10.14% samples extremely poor, 21.7% 26% medium, 42% good excellent. PTE varied, HPI values indicating central area 53.6% collected (HPI < 30), but south high > 51). Ecological below threshold 100% (RI confirming safety regarding PTEs. In comparison, hazard (HI) through oral/ingestion, exhibited HI ranging 0.012 2.16, while children showed higher values, 0.045 8.25. However, oral/ingestion exceeded safe limits (HI oral 1), posing significant exposure manganese (HQ El-Wasta El-Fashn, necessitating further treatment

Contamination levels of water sources and the associated nitrate health risks to six age groups

Toxin Reviews, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 14

Published: Aug. 21, 2024

Advancements in health risk assessment are vital for protecting public health. This study's objectives were to analyze the degree of nitrate contamination, multi-route risks six age groups, and potential sources water contaminants a Nigerian suburban area. Nitrate pollution index (NPI) results between −1.00 0.06, indicating low human impact. According analysis, infants ages 6 12 months more vulnerable, whereas humans 20 > 60 have lower risks. may be due fact that bodily tissues vulnerable potentially toxic contaminants. For all categories, associated with ingestion was greater than dermal contact. Varimax-rotated factor analysis five principal component extractions revealed varied from geogenic processes human-initiated activities.

An integrated computational and graphical approach for evaluating the geochemistry and health risks of nitrate-contaminated water for six age groups

Journal of Environmental Science and Health Part C, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 34

Published: Dec. 22, 2024

Nitrate contamination in drinking water poses significant health risks, particularly rapidly urbanizing areas of developing countries. This study presents an integrated computational and graphical approach to evaluate the geochemistry risks nitrate-contaminated for six age groups Southeast, Nigeria. The research employed a detailed methodology combining nutrient pollution index (WNPI), nitrate (NPI), (WPI), geochemical plotting techniques, stoichiometry, risk computations. Water samples from several locations were analyzed physicochemical parameters concentrations. Results revealed predominantly acidic conditions varying levels contamination. Geochemical analysis indicated that silicate weathering ion exchange processes primary influences on chemistry. WPI identified 14.29% as "extremely polluted" (WPI > 1), while WNPI classified 7.14% "moderately (WNPI 1). However, NPI categorized safe, indicating low inputs anthropogenic sources. Health assessments low-moderate with highest total hazard 0.839 6-12 months group; thus, higher vulnerability infants. Oral exposure was found be dominant pathway, contributing over 99.90% risk. provides crucial insights achieving Sustainable Development Goals (SDGs) related quality public protection. offers robust framework resource management interventions risk-prone areas. Future should focus expanding spatial coverage, incorporating sensitivity analyses, exploring advanced technologies real-time monitoring predictive modeling quality.

Groundwater Quality and Associated Health Risks in the Eastern Region of Ghana

Heliyon, Journal Year: 2025, Volume and Issue: 11(2), P. e41910 - e41910

Published: Jan. 1, 2025

In the Eastern Region of Ghana, 95 % residents have access to boreholes. However, approximately 30 these boreholes are characterized by unpleasurable taste, odour, oily scum and particulate matter. Thus, this study aimed assess water quality, predict sources groundwater contaminants, evaluate human health risk generate spatial distribution maps. achieving this, quality 136 in region was evaluated through Water Quality Index (WQI) Groundwater Pollution (GPI) analyses. Multivariate statistical procedures, namely, principal component correlation analyses were employed define major pollutants their possible sources. Non-carcinogenic infants, children adults nitrates, iron, manganese fluorides ingestion also assessed. The results revealed that is generally slightly acidic with a mean pH 6.30. WQI analysis grouped 68 samples under 'excellent' 'good' types remaining percent categorized 'poor', 'very poor' 'unsafe' drinking types. GPI classified %, 2.21 2.79 as 'insignificant', 'low' 'highly' polluted zones. From multivariate analyses, dominant manganese, chlorides, sodium, fluorides, potassium, turbidity, total suspended dissolved solids, hardness, alkalinity, sulphates, nitrates phosphates. contaminants primarily from rock-water interactions fertilizers. Health assessment for iron 23, 17 15 likely pose non-carcinogenic respectively. maps indicated most vulnerable districts Atiwa East, Fanteakwa North, Achiase, Birim South, Akwapim, Suhum Ayensuano. findings, it imperative appropriate remediation measures implemented protect public health.
