Monte Carlo simulation and PMF model for assessing human health risks associated with heavy metals in groundwater: a case study of the Nubian aquifer, Siwa depression, Egypt

Frontiers in Earth Science, Год журнала: 2024, Номер 12

Introduction The groundwater in arid countries such as Egypt represent the main water resources desert regions due to long distance between these (oasis) and Nile River. Contamination of limited with toxic metals threaten health individuals regions. Methods current study integrates isotopic tracers, hydrogeochemistry, geophysical logs, positive matrix factorization (PMF model), Monte Carlo (MCS) simulation for pollution source apportionment risks associated heavy Nubian Sandstone aquifer (NSSA). Results Discussion resource used drinking purposes (NSSA) is pale meteoric (non-rechargeable aquifer). Silicate weathering, old trapped sea water, reverse ion exchange evaporation, dissolution are dominant mechanisms controlling chemistry. PMF model showed that major ions NSSA originated from four significant sources (anthropogenic activities, minerals, iron-bearing mixing seawater, hydrothermal water). total risk (HI) oral values highlighted non-carcinogenic dangers adults children through exposure. At same time, dermal contact posed a no high children. Most samples had carcinogenic (CR) higher than allowed limits (1.0E-4) like Cadmium, chromium, lead, suggesting effects across all age groups. approach-based concern evaluation assessed 5th % CR (child) 0.00012, 0.0036, 0.0088 Cd, Cr, Pb, respectively, indicating more potential Urgent comprehensive treatment measures imperative mitigate identified area.

Chemometric Analysis of Heavy Metal Contamination in Water Sources: A Risk Assessment Approach

Опубликована: Март 25, 2025

Heavy metal contamination in water sources is a major environmental and public health concern, necessitating advanced analytical techniques for effective assessment mitigation. This study systematically reviews chemometric approaches used to evaluate heavy pollution, focusing on pollution indices, multivariate statistical techniques, risk models. The methodology involved an extensive review of peer-reviewed literature from databases such as Elsevier, Springer, MDPI, with inclusion criteria emphasizing studies contamination, evaluation, applications quality analysis. Findings indicate that metals lead (Pb), cadmium (Cd), arsenic (As) are prevalent contaminants, levels varying across regions. Chemometric methods, including cluster factor analysis, principal component Monte Carlo simulations, have proven identifying sources, assessing risks, guiding remediation strategies. highlights the necessity integrating tools into management frameworks improve monitoring develop targeted mitigation measures.

Remediation Journal, Год журнала: 2025, Номер 35(3)

Опубликована: Апрель 1, 2025

ABSTRACT The world is battling pollution issues that are exacerbated by increasing industrialization and population growth. With the current aims of sustainable development, green remediation (GR) advocated as an approach to minimize environmental footprint during hazardous site remediation. Of course, GR comes with its challenges but offers a reliable mode cleanup ensuring protection achieved projects while also promoting concepts. Africa fast‐growing continent several developmental could pose challenge implementation GR. This paper, through thorough literature search analysis, elucidate concept GR, implementation, challenges, opportunities in Africa. research deduced such financing, lack skillsets technology, guidelines policies hinder application study recommends use awareness tool introduce provides on ways which can be incorporated into

Rapid Estimation of Soil Moisture Using Spectroscopic Sensor

Communications in Soil Science and Plant Analysis, Год журнала: 2024, Номер 56(4), С. 648 - 659

Опубликована: Ноя. 10, 2024

Soil moisture plays a significant role in the global hydrological cycle field of agriculture, environment science, urban planning and construction, forestry many more. can be determined using various approaches, however some limitations these approaches are longer time duration, labor intensive, require installation maintenance, expensive, lower resolution, etc. This research work proposes soil detection method which is portable, economic efficient. Spectroscopic sensor enables rapid estimation photodiodes varying sensitivities wavelengths across broad spectrum light, allowing precise identification analysis samples based on their unique spectral fingerprints. In this study, relation between output data percentage value obtained from gravimetric has been established. Using regression methods, highest correlation coefficient was found case polynomial function order 3. Residual values all were then calculated by comparing with expected function. Result showed that 705 nanometers (nm) wavelength least residual value, thus signifying equation 3 at nm perfectly demonstrates reading. Furthermore, results verified optimization closeness coefficient, verifying model observations. helpful determining instantaneously instead hours as seen traditional methods.
