Comprehensive health risk analysis of heavy metal pollution using water quality indices and Monte Carlo simulation in R software

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.

Assessment of Carcinogenic and non-carcinogenic risk indices of heavy metal exposure in different age groups using Monte Carlo Simulation Approach

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

Published: Dec. 5, 2024

Abstract Dermal contact, ingestion and inhalation of heavy metal poses significant health risk in human subjects. The exposure could be via potable water, soil or air. current experiment design focuses on media exposure. Advanced probabilistic geospatial methods are used this study which evaluates contamination levels risks associated with iron (Fe), arsenic (As), zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), cadmium (Cd) samples. samples were collected analysed using ICP-OES after tri-acid digestion, indices such as Geoaccumulation Index (Igeo), Contamination Factor (CF), Pollution Load (PLI), Hazard Quotient (HQ), (HI), Carcinogenic Risk (CR) to assess environmental impacts across the age groups oral ingestion, dermal contact. indicates concentrations follow order Ni > Zn Pb Cu Cr As Cd, more than 60% demonstrating pollution levels. computational method revealed substantial non carcinogenic (HQ 1) (33%) population related Geospatial analysis Monte Carlo simulations helped identifying hotspots tropical coastal area emphasizing need for targeted remediation focusing Pb.

Global water quality indices: Development, implications, and limitations

Total Environment Advances, Journal Year: 2023, Volume and Issue: 9, P. 200095 - 200095

Published: Dec. 30, 2023

Water quality index is crucial for improving water and clean supply to achieve sustainable development goals directly related water, agriculture, biodiversity, health, climate actions. examines the vital relationship between demand, focusing on role that (WQ) plays in integrated environmental management. This study evaluates methodology limitations of several studies by doing a thorough examination regional global WQ indices synthesizing results. Quality Indices (WQIs) have been used measure since 1960s, offering mechanism changes at specific needs challenges. review assesses using indexes based aims provide detailed analysis various WQIs utilized across globe. The stated measurements into single number, which are categorized as poor, marginal, fair, excellent, exceptional, depict clearly understandably WQ. However, region-specific required due variety standards established national international organizations, well different pollution prevention elements. Thus, there continual interest developing exact suitable region or geographic area. Still, structured in-depth literature examine current research, evaluate, highlight drawbacks methodologies employed each phase. offers insightful information researchers, decision-makers, practitioners tackling ever-changing problems resource debate concentrates WQI-related topics, such how evolved, what variables define their parameter requirements, restrictions have, widely used, benefits over one another regarding worldwide applicability.

Water quality assessment using IRWQIsc and NSFWQI water quality indicators; A case study: Talar River (Iran)

Heliyon, Journal Year: 2025, Volume and Issue: 11(2), P. e41812 - e41812

Published: Jan. 1, 2025

One of the driest countries in world, Iran has been facing several challenges related to water shortage, leading serious social, economic, and environmental impacts. Given escalating urbanization industrial development within Iran, a comprehensive assessment surface quality utilizing both US National Sanitation Foundation Water Quality Index (NSFWQI) for (IRWQIsc) is imperative. This study aimed evaluate Talar River Mazandaran, 2023, through IRWQIsc NSFWQI. was conducted River, located Mazandaran Province Iran. samples from were collected assess 11 physicochemical parameters 10 sampling Points. A total 60 monthly during winter summer 2023. The NSFWQI selected overall River. Nitrate (NO3 -) concentrations ranged 29.32 85.89 mg/L across seasons, with average values falling World Health Organization (WHO) standards. Phosphate (PO4 3-) Chemical Oxygen Demand (COD) levels exceeded WHO limits on occasion, while turbidity electrical conductivity (EC) consistently surpassed Environmental Protection Agency (EPA) guidelines. pH Biochemical (BOD) remained acceptable ranges. indicated generally poor all sites, slight seasonal variations suggesting slightly better conditions indicates that NO3 - PO4 3- meet limits, but COD, turbidity, EC exceed recommended threshold. highlight resulting agricultural pollution. Urgent integrated management essential mitigate these impacts safeguard river health face pressures.
