Published: July 5, 2023

Groundwater contamination by nitrate and heavy metals is a growing global concern due to its detrimental effects on human health through ingestion dermal exposure. This study aimed assess the concentrations of (Pb, Cu, Cd, Fe) in groundwater evaluate associated risks among different age groups (females, males, children) Nnewi Awka regions southeast Nigeria. Standard methods were followed. Ten samples collected from each locality, their physicochemical parameters analyzed. The evaluation metal levels was conducted using cancer hazard index as indicators public impact. results showed that while within acceptable limits, exceeded permissible all samples. Carcinogenic risk (CR) analysis revealed approximately 40% 80% permitted range ≤1 × 10 −6–1 −4. In region, order toxicity Cd > Pb Cu Fe, Awka, it resulting severe non-carcinogenic hazards for users. identified most significant contaminants impacting water quality both regions. Children exhibited greater vulnerability compared adults areas. These findings contribute our understanding localized contamination, highlight children, emphasize importance regular monitoring management practices.

Published: May 2, 2023

The majority of people living on earth rely groundwater as their primary supply water for daily needs. However, human activities continuously threaten this natural resource. In an attempt to unravel the extent impact human-related physicochemical characteristics in Nnewi and Awka urban clusters (Nigeria), several techniques were integrated study. Groundwater samples warm acidic nature. Concentrations SO42-, NO3-, PO43-, Cl-, HCO3-, Ca2+, Mg2+, Na+ K+ within set benchmarks. nutrient pollution index (ranging from 0.060 0.745), nitrate (varying between −0.999 −0.790) 0.057 0.630) estimated anthropogenic contamination showed low characteristics. health risks due ingestion skin absorption nitrate-contaminated computed six age groups (6–12 months, 5–10 years, 10–15 15–20 20–60 years >60 years) risk values that < 1, implying chronic humans. cumulative total hazard ranged 0.006 0.787 with a mean value 0.167. Chemometric analyses geochemical plots revealed relationships variables sources. Chadha's plot 55% Ca2+-Mg2+-Cl- waters, predominating over Na+-Cl- Ca2+-Mg2+-HCO3- waters. Bivariate multivariate also indicated impact. Furthermore, principal component analysis R-type hierarchical clustering confirmed chemistry quality mostly influenced by geogenic processes than acts. Conclusively, influence is low. These findings would be useful future monitoring both clusters.

Evaluation of oral and dermal health risk exposures of contaminants in groundwater resources for nine age groups in two densely populated districts, Nigeria

Heliyon, Journal Year: 2023, Volume and Issue: 9(4), P. e15483 - e15483

Published: April 1, 2023

Human health and the sustainability of socioeconomic system are directly related to water quality. As anthropogenic activity becomes more intense, pollutants, particularly potentially harmful elements (PHEs), penetrate systems degrade The purpose this study was evaluate safety using groundwater for domestic drinking purposes through oral dermal exposure routes, as well potential risks posed humans in Nnewi Awka regions Nigeria. research involved application a combination National Sanitation Foundation Water Quality Index (NSFWQI), HERisk code, hierarchical dendrograms. Additionally, we utilized regulatory guidelines established by World Health Organization Standard Nigeria compare elemental compositions samples. physicochemical parameters NSFWQI evaluation revealed that majority samples were PHE-polluted. Based on it discovered both regions, risk levels higher people aged 1 <11 >65 than 16 <65. Overall, shown all age categories appeared be vulnerable due consumption absorption PHEs, with Cd > Pb Cu Fe from Awka. Summarily, groups middle less susceptible possible issues children elderly individuals. Hierarchical dendrograms correlation analysis showed spatio-temporal implications quality human area. This could help local government agencies make informed decisions how effectively safeguard environment while also utilizing resources sustainably.

Protected areas are significant due to the high value of natural resources they shelter. This study's primary objective is assess quality status water (13 lakes and Tisa River) localized in protected area River on territory Romania. A number 13 surface (Tisa situated through Natura 2000 ecological network studied. The chemistry potential pollution were analyzed by measuring analyzing a set twenty elements sixteen physico-chemical parameters. impact anthropogenic activities was settled applied analysis obtained results. human health risk noticed. Results indicated that waters rich Ni Fe probably interaction with groundwater Ni. Waters characterized contamination, which if directly or food chain consumed could negatively influence health. Piper Gibbs plots studied divided into three categories based water-rock interactions: mixed Ca2+-Na+-HCO3-, CaCO3-, Na+-HCO3-. Likewise, indices (Heavy metal Pollution Index, HPI Heavy Evaluation HEI) correlated As, amounts. findings this research imply influenced geogenic origin emergence activities. significance related understanding mechanisms quality, improving conserving resources, correspondingly any risks be identified.
