Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Sept. 22, 2023

Rapid urbanization, population growth, agricultural practices, and industrial activities have led to widespread groundwater contamination. This study evaluated heavy metal contamination in residential drinking water Shiraz, Iran (2021). The analysis involved 80 samples collected across wet dry seasons. Water quality was comprehensively assessed using several indices, including the metals evaluation index (HEI), pollution (HPI), degree (CD), (MI). Carcinogenic non-carcinogenic risk assessments were conducted deterministic probabilistic approaches for exposed populations. In assessment, chronic daily intake (CDI), hazard quotient (HQ), (HI) are employed. precision of assessment bolstered through utilization Monte Carlo simulation, executed R software platform. Based on results, both seasons, Zinc (Zn) consistently demonstrates highest mean concentration, followed by Manganese (Mn) Chromium (Cr). During 25% 40% regions exhibited high CD, respectively. According Cr presents CDI HQ children adults, Mn, As HI values, indicating elevated children. carcinogenic while lowest Cd sensitivity found that concentration ingestion rate significantly impact risks. These findings provide critical insights shaping policy allocating resources towards effectively managing water.

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 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.
