New approach into human health risk assessment associated with heavy metals in surface water and groundwater using Monte Carlo Method

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 10, 2024

Abstract This study assessed the environmental and health risks associated with heavy metals in water resources of Egypt's northwestern desert. The current approaches included Spearman correlation matrix, principal component analysis, cluster analysis to identify pollution sources quality-controlling factors. Various indices (HPI, MI, HQ, HI, CR) were applied evaluate human risks. Additionally, Monte Carlo method was employed for probabilistic carcinogenic non-carcinogenic risk assessment via oral dermal exposure routes adults children. Notably, all exhibited high HPI MI values exceeding permissible limits (HPI > 100 6), respectively. Furthermore, HI indicated significant both children, while contact posed a 19.4% samples 77.6% children (HI 1). Most CR 1 × 10 –4 Cd, Cr, Pb, suggesting vulnerability effects age groups. simulations reinforced these findings, indicating impact on adults. Consequently, comprehensive treatment measures are urgently needed mitigate Siwa Oasis.

Abstract The qualitative and quantitative assessment of groundwater is one the important aspects for determining suitability potable water. Therefore, present study has been performed to evaluate quality Achhnera block in city Taj, Agra, India, where an water resource. samples, 50 number were collected analyzed major ions along with some trace element. This further investigated applicability index (GWQI), principal component analysis (PCA) mark out geochemical solutes responsible origin release into groundwater. results confirm that, majority samples alkaline nature. variation concentration anions varied sequence as, HCO 3− > Cl − SO4 2− F while contrast cations as Na Ca Mg K. Piper diagram demonstrated hydro chemical facies which found (sodium bicarbonate or calcium chloride type). plot Schoellar reconfirmed that + 2+ ions, contrast; bicarbonates chloride. showed mostly ranged between 105 185, hence, area fell category unsuitable drinking purpose category.

Advanced approach combines integrated weight water quality index and potential toxic elements for environmental and health risk assessment supported by simulation technique in Oued Souf, Algeria

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 1, 2024

Abstract The current research study evaluated the health and environmental risks issues associated with potentially toxic elements (PTEs) in complex terminal aquifer located Algerian desert. methods used included principal component cluster (dendrogram) analysis to estimate source of ions contamination. Various indices such as Heavy Metal Pollution Index (HPI), Index, hazard quotient, index (HI), cancer risk (CR) were applied assess both human risks. Furthermore, Monte Carlo method was for probabilistic assessment carcinogenic non-carcinogenic through oral dermal exposure routes adults children. results revealed that approximately 16% samples fell within low pollution category (HPI < 100), indicating relatively lower levels heavy metal However, remaining 84% exhibited high levels, a significant presence pollutants northeastern part investigated area. calculated average (RI) collected 18.99, range from 0.03 103.21. This indicates large portion, 82% samples, could cause ecological (RI 30), whereas 18% indicate risk. HI ingestion showed had values ranging 0.231 1.54, while children higher values, 0.884 5.9 (Fig. 5a). For exposure, ranged 2.71E−07 8.74E−06 children, 2.18E−06 7.03E−05. These findings highlight potential PTEs underscore increased vulnerability metals Fe, Mn, Pb, Cr. Most CR exceeding 1 × 10 −4 chromium (Cr) lead (Pb), effects adults.
