Water pollution poses significant environmental and health challenges globally due to increasing industrialization urbanization, which have led a rise in wastewater discharges containing hazardous pollutants. These pollutants not only degrade aquatic ecosystems but also pose risks human health. To address these issues, researchers been exploring various treatment technologies including adsorption specific can be removed efficiently selectively using adsorbents. Magnetic adsorbents, especially magnetite (Fe3O4), emerged as promising adsorbent material for water purification. Its high surface area, supermagnetism, ease of functionalization make it suitable the many contaminants. In this Review, we highlight recent developments Fe3O4 nano adsorbents synthesis, properties, strategies, challenges. The stability were discussed. A comparison Fe3O4-based traditional was then addressed. Finally, an outlook on opportunities future advancement practical application is provided. Such interdisciplinary research field expected stimulate further nanoscience advanced nanotechnology treatment.

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.

Abstract This research evaluates the environmental and health risks linked to potentially toxic elements (PTEs) PAHs along western coast of Gulf Suez, Egypt. study investigated concentration 16 PAH compounds in Suez Gulf, revealing significantly higher levels than EU (0.20 µg/L) US (0.030 standards. The average total across eight locations was higher, with area having highest at 479 µg/L. Pyrene (Pyr) dominant a 443 µg/L while acenaphthylene (Ace) had lowest 0.120 Northern Zaafarana. Carcinogenic (CAR) ranged from 8.67 Ras Gharib 29.62 highlighting urgent need for regulatory measures. Confirmatory ratios pointed industrial shipping influences as petrogenic sources.

This research looks at how the growth of cities and industries affects levels heavy metals in soil, which can impact people's health. We find out where pollution comes from, such as factories, car fumes, improper waste disposal, by reviewing existing studies. use different methods to test soil for study exposure these urban areas The evidence shows a connection between high city health problems like breathing issues, brain disorders, overall toxicity body. also explore get into human body, highlighting importance understanding they are available ways people exposed. To deal with polluted soils, we look manage suggest sustainable reduce metal pollution. Our discoveries add what know about environmental health, emphasizing need actions protect residents. Ultimately, this aims give important information insights policymakers, planners, public officials managing lessening risks linked contamination soils.

The success of industrial operations depends on the effective identification, appraisal, and mitigation possible hazards associated environmental concerns. This report provides a complete review management techniques at Sukari Gold Mine (SGM), located in southeastern desert Egypt. Extensive measurements were taken to assess air water quality, identify hazards, analyze risks SGM premises. Air quality noise intensity levels measured 39 places around mine's working region. findings found noncompliance with Egyptian Environmental Law's (EEL4/94) exposure limitations, Power Generator House having maximum 107 dB. Remedial measures such as personal protective equipment (PPE) limit reduction strategies are being considered address elevated levels. Measurements particulate matter (PM10) noxious gases (e.g., CO, SO2, NO2, HCN, NH3) conducted workplace ambient environments. Elevated PM10 concentrations particularly concerning underground regions, forcing deployment depression improved PPE measures. While gas emissions from most activities remained under regulatory limits, select zones showed hydrogen cyanide (HCN) that exceeded permitted thresholds, necessitating specific control actions. Using hazard index (HI) risk rating assessments, this study different profiles across SGM's workplaces, focusing high-risk regions for focused intervention. Additionally, assessment near Tailing Storage Facility (TSF) was monitor impact mining groundwater quality. revealed region belongs Na-K-Cl-SO

Abstract Evaluation of water quality is crucial for managing surface effectively, ensuring its suitability human use, and sustaining the environment. In lower Danube River basin, various methods were employed to assess irrigation, drinking, health risk purposes main mechanism control chemistry. These included indicators (WQIs), complex statistical analyses, geographic information systems (GIS), Monte Carlo simulation, geochemical modeling. Physicochemical analyses samples revealed primarily Ca–Mg–HCO 3 − dominant types. Principal component analysis (PCA), ionic ratios piper, chloro alkaline index, Chadha, Gibbs diagrams identified three distinct characteristics influenced by water-rocks interaction, evaporation, ions exchange, activities. The modeling showed water’s strong ability dissolve gypsum, halite, anhydrite (SI < 0) precipitate aragonite, dolomite, calcite with saturation index (SI) value greater than 0 along flow path. irrigation (IWQI = 99.6–107.6), sodium adsorption ratio (SAR 0.37–0.68), percentage (Na% 13.7–18.7), soluble (SSP 12.5–17.5), Potential Salinity (PS 0.73–1.6), Residual Sodium Carbonate (RSC 1.27–0.58) values used, mainly indicating acceptable some limitations. was unsuitable drinking based on WQI (WQI 81–104). Oral exposure children specific components a higher hazard (HI > 1) compared adults, 2.1 times overall non-carcinogenic index. However, simulation demonstrated negligible iron, manganese, nitrate hazards both age groups. findings are valuable management decisions, contributing long-term resource sustainability.
