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.

Assessment of human health risk from potentially toxic elements and predicting groundwater contamination using machine learning approaches

Journal of Contaminant Hydrology, Journal Year: 2024, Volume and Issue: 261, P. 104307 - 104307

The Rooppur Nuclear Power Plant (RNPP) at Ishwardi, Bangladesh is planning to go into operation within 2024 and therefore, adjacent areas of RNPP gaining adequate attention from the scientific community for environmental monitoring purposes especially water resources management. However, there a substantial lack literature as well datasets earlier years since very little was done beginning RNPP's construction phase. Therefore, this study conducted assess potential toxic elements (PTEs) contamination in groundwater its associated health risk residents part during year 2014–2015. For achieving aim study, samples were collected seasonally (dry wet season) nine sampling sites afterwards analyzed quality indicators such temperature (Temp.), pH, electrical conductivity (EC), total dissolved solid (TDS), hardness (TH) PTEs including Iron (Fe), Manganese (Mn), Copper (Cu), Lead (Pb), Chromium (Cr), Cadmium (Cd) Arsenic (As). This adopted newly developed Root Mean Square index (RMS-WQI) model scenario whereas human assessment utilized quantify toxicity PTEs. In most sites, concentration found higher season than dry Fe, Mn, Cd As exceeded guideline limit drinking water. RMS score mostly classified terms "Fair" condition. non-carcinogenic risks (expressed Hazard Index-HI) revealed that around 44% 89% adults 67% 100% children threshold set by USEPA (HI > 1) possessed through oral pathway season, respectively. Furthermore, calculated cumulative HI throughout period. carcinogenic (CR) PTEs, magnitude decreased following pattern Cr Cd. Although current based on old dataset, findings might serve baseline reduce future hazardous impact power plant.

Chemical Assessment of Drinking Water Quality and Associated Human Health Risk of Heavy Metals in Gutai Mountains, Romania

Toxics, Journal Year: 2024, Volume and Issue: 12(3), P. 168 - 168

Published: Feb. 22, 2024

Chemical data compiled from field and laboratory studies were analysed on drinking water sources a mountain area (Gutai Mountains) in Romania. Six physico-chemical indicators, nine anions, twenty-one metals determined analysed. The results of this study showed that waters are generally rich NH4+ NO2−, exceeding the recommended limit 0.5 mg NH4+/L, while some As, Cd, Mn Pb, but with concentrations below limits concerning use purposes. applied heavy metal pollution indices (scores: 0.56–47.9) indicate more than 50% samples characterized by medium degrees. Based obtained, it was geological human activities influential enriching studied chemicals considered. Emphasizing aspect related to importance clean chemical status must characterize used for purposes, health risk assessment implemented. indicated even though metals, scores lack non-carcinogenic risks Mn, Cd Cu. Nevertheless, obtained significant at national international levels offering perspective determining potential associated area.

Groundwater contamination through potentially harmful metals and its implications in groundwater management

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Published: Nov. 7, 2022

Groundwater contamination through potentially harmful metals (PHMs) is an environmental hazard in Pakistan with significant human health risk reports. The current research was conducted Sheikhupura District, which a major industrial site Punjab, Pakistan. According to the Punjab Directorate of Industries Pakistan, there are total 748 industries this area. These produce lot waste and effluent, contaminate environment toxic materials. Continuous irrigation effluent sewage sludge may make groundwater sources vulnerable. Therefore, we collected 243 samples from community tube wells investigate quality cconcerning PHM contaminations study This presents values pH, dissolved solids (TDS), electrical conductivity (EC), like arsenic (As), manganese (Mn), lead (Pb), zinc (Zn), copper (Cu), nickel (Ni), iron (Fe). PHMs such as As (91%), Mn (14%), Pb (97%), Fe (45%), Zn (15%), these were beyond permitted limit recommended by world organization (WHO). Principal component analysis (PCA) results variability (60%) reveal that area contaminated about 30.9, 31.3, 37.6% resulted geogenic sources, anthropogenic or both respectively. Such include rock-water interaction, mining actions, agricultural practices, domestic sewage, Saturation indices show aquifers saturated hydroxide, goethite minerals, indicating minerals have vital role groundwater. Health assessment predicted non-carcinogenic (HQ) found within permissible (<1), except (1.58E+00) for children, while carcinogenic (CR) all selected lower than maximum threshold CR value (1 × 10 −4 ).
