Published: June 17, 2024

Groundwater contamination was studied at several hotspot sites in the Majdanpek copper mining area (Serbia). These include a milling facility, metallurgical wastewater treatment plant, heavy vehicle service area, and waste disposal site. In addition to Cu, high concentrations of As metals (Cd Pb) were detected groundwater soil same sampling points. Mining operations transport activities have been identified as main sources pollution. The migration from groundwater, expressed concentration ratio, highest for Co lowest Mn. environmental implications pollution using metal index (HPI), Nemerov (NPI), hazard (HI), incremental lifetime cancer risk (ILCR).

Arsenic‐contaminated groundwater of the Western Banat (Pannonian basin): Hydrogeochemical appraisal, pollution source apportionment, and Monte Carlo simulation of source‐specific health risks

Water Environment Research, Journal Year: 2024, Volume and Issue: 96(8)

Published: Aug. 1, 2024

Abstract Due to rapid urbanization and industrial growth, groundwater globally is continuously deteriorating, posing significant health risks humans. This study employed a comprehensive methodology analyze in the Western Banat Plain (Serbia). Using Piper Gibbs plots, hydrogeochemistry was assessed, while entropy‐weighted water quality index ( EWQI ) used evaluate quality. Pollution sources were identified using positive matrix factorization (PMF) accompanied by Pearson correlation hierarchical cluster analysis, Monte Carlo simulation assessed associated with consumption. Results showed that groundwater, mainly Ca–Mg–HCO 3 type, mostly suitable for drinking. Geogenic pollution, agricultural activities, sewage major pollution sources. Consumption of contaminated poses serious non‐carcinogenic carcinogenic risks. Additionally, arsenic from geogenic source found be main contributor, considering its worryingly elevated concentration, ranging up 364 μg/L. These findings will valuable decision‐makers researchers managing vulnerability. Practitioner Points Groundwater severely As northern part area. The predominant hydrochemical type area . PMF method apportioned three rock dissolution as primary risk contributor. Health mortality are positively correlated.

The occurrence and distribution of yttrium rare earth elements (REYs), along with major heavy metal(loid)s (HMs) in coal fly ash (CFA) from five coal-fired power plants (CFPPs), were analyzed, the REY-associated ecological health risks assessed. individual REYs CFA abundant following order: Ce > La Nd Y Pr Gd Sm Dy Er Yb Eu Ho Tb Tm Lu. total REY content ranged 135 to 362 mg/kg, averaging 302 mg/kg. mean light-to-heavy ratio was 4.1, indicating prevalent light enrichment CFA. Significantly positive correlations between suggested that they coexist share similar origins estimated pose low moderate risks, risk index (RI) values ranging 66 245. hazard (HI) target cancer (TCR) CFA, be higher for children (HIc = 0.15, TCRc 8.4 × 10−16) than adults (HIa 0.017, TCRa 3.6 10−16), well below safety limits (HI 1, TCR 1.0 10−6). However, danger human posed by HMs same samples 5.74, 2.6 10−4, 1.1 10−4) exceeded safe thresholds (excl. HIa 0.63). RI HI attributed 14% 2.6%, respectively, include HMs.

Recovery of Rare Earth Elements from Coal Fly and Bottom Ashes by Ultrasonic Roasting Followed by Microwave Leaching

Metals, Journal Year: 2024, Volume and Issue: 14(4), P. 371 - 371

Published: March 22, 2024

Considering the rising demand for rare earth elements (REEs), researchers are looking new sources their extraction, thereby fostering economic and environmentally justified processing solutions. Among potential industrial sources, coal fly ash emerges as one of most promising. The recovery REEs from bottom ashes derived different thermal power plants was main focus this study. A dual-step methodology conducted on samples, which involved an ultrasonic roasting process to disintegrate silica matrix, followed by a microwave-assisted acid leaching step extract REEs. procedure studied using Plackett–Burman design, Box–Behnken design subsequently implemented optimize procedure. optimized set up at 95 °C 10 min with ash-to-roasting agent (3M NaOH) ratio 0.5:1 (m/V). For leaching, optimal conditions were obtained 174 30 HCl ÷ HNO3 mixture (1:1 V/V). standard reference material (NIST 1633c) used in conclusive experiments estimate average (80%) green aspects evaluated several metrics (atom economy, E-factor, energy consumption). proposed outperforms high-temperature procedures terms greenness; however, REE rate is lower.

Fluoride and nitrate contamination in groundwater is a global concern due to their toxicity associated negative health effects. This study incorporated comprehensive methodology, including hydrogeochemical analysis, drinking irrigation water quality assessment, source apportionment, risk estimation of fluoride lithium ore deposit basin western Serbia. Groundwater major ion hydrogeochemistry was governed by water–rock interactions, with Ca-Mg-HCO3 identified as the predominant type. The entropy-weighted index (EWQI), sodium adsorption ratio (SAR), percentage (%Na) revealed that 95% samples were excellent good for both irrigation. Moreover, results showed fluorides geogenic origin, whereas nitrates originated from agricultural activities. Although levels relatively low, averaging 1.0 mg/L 11.1 mg/L, respectively, assessment ingestion such can still lead non-cancerous diseases. threshold one hazard exceeded 15% 35% adults children, respectively. Children more vulnerable non-carcinogenic risk, being primary contributing factor. outcomes serve reference other lithium-bearing areas guide management regional resources.
