Results demonstrated that the system was more effective at low concentrations (0.2 mmol/L) and flow rates (0.2 mL/min), for both antibiotics, with extended breakthrough times, indicating that OFL (1256.39 min) and CIP (1314.60 min) were completely removed for a longer period, and the lowest mass transfer zone for OFL (2.75 cm) and CIP (3.44 cm).

Once in the sea, BC has the potential to affect nutrient biogeochemical cycles. In a series of four incubation experiments (Adriatic Sea and Ligurian Sea) and a pilot study, we have challenged the microbes with heavy loads of BC (24 mg L^-1) in order to study the short-term BC effect on microbial dynamics and activities. Upon BC amendment, heterotrophic prokaryotes increased in abundance while viruses decreased. At the microscale, microbes became attached to BC particles, very heterogeneous in shape and size and enriched in proteins over time; these findings were confirmed by Fourier transform-IR spectroscopy and atomic force microscopy. Enzymatic degradative activities, proteases, and alkaline phosphatases were suppressed in the BC treatments despite an enhancement in prokaryotic carbon production. The 16S rRNA gene amplicon sequencing analysis did not show a significant shift in the microbial communities. Despite this, indicator species analysis revealed that Arcobacter and Pseudoalteromonas genera were statistically associated with the BC treatment at 48 h, thus suggesting their adaptive strategies to utilize BC.

This study evaluates the WF_grey using real data from a municipal wastewater treatment plant (WWTP) and its associated RWB over an eight-year period (2016-2023). A wide range of pollutants were considered, including organic compounds, solids, nutrients, and heavy metals. The analysis considered three scenarios: (a) untreated wastewater discharge, (b) treated effluent discharge, and (c) treated wastewater reuse for agricultural purposes. Results indicate that the WWTP significantly reduces pollutant loads, with scenario (b) showing an average 8-fold decrease in WF_grey compared to scenario (a). Ammonium (in scenario (a)) and phosphorus (in scenario (b)) emerged as the primary contributors to WF_grey, highlighting the limited phosphorus removal due to the absence of dedicated chemical or biological treatments. Lead was found to be the most impactful heavy metal in several instances, underlining the importance of monitoring low-concentrated contaminants. Ammonium and total nitrogen showed the highest removal efficiency, whereas phosphorus removal was relatively inefficient, reinforcing the need for future plant upgrades. Furthermore, the reuse scenario (c) demonstrated the potential of nutrient-rich treated effluent for irrigation, particularly during dry summer months, offering dual benefits of pollution reduction and resource recovery. Overall, WF_grey proved to be a robust and accessible indicator for evaluating WWTP performance, identifying critical pollutants, guiding plant optimization, and supporting sustainable discharge and reuse strategies. Future developments should expand monitoring to emerging contaminants such as pharmaceuticals, pesticides, microplastics, and additional heavy metals to ensure comprehensive environmental protection.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A commercial PAC based on eucalyptus wood was characterized and applied to a raw stabilized leachate sample, resulting in a substantial reduction in the concentration of dissolved organic carbon (DOC), especially the recalcitrant fractions such as the humic and fulvic compounds. The PAC exhibited high organic compound affinity, with an adsorption capacity of 753 mg.g^-1 for true color, which was well described by the Langmuir isotherm model. It was possible to reduce the true color by more than 97% using 50 mg.L^-1 of PAC. Additionally, it was possible to effectively regenerate the PAC using a solution of phosphoric acid, enabling the complete recovery of its adsorption capacity for all the analyzed parameters.

Thus, the present research aimed to assess the geochemistry and suitability of the groundwater for drinking and domestic use in the Umaria coalfield. To accomplish the goals, one hundred groundwater samples were collected on a seasonal basis from various locations in the Umaria coalfield and analysed for pH, electrical conductivity, turbidity, total dissolved solids (TDS), and major ions. The pH of the tested samples ranges from 6.4 to 8.0 in the post-monsoon season and 6.2 to 8.0 in the pre-monsoon season, indicating a slightly acidic to slightly alkaline nature. The post-monsoon season samples have a range of TDS from 74-1,325 mg/L and 87-1,611 mg/L in the pre-monsoon season. The concentration of cations plus anions in the groundwater is 609 mg/L in the post-monsoon season and 765 mg/L in the pre-monsoon season, showing minimal seasonal change in the cationic and anionic chemistry. The groundwater in the studied region shows Ca-Mg-HCO₃ and Ca-Mg-SO₄-Cl hydrogeochemical facies in both seasons. The dominant cations are Ca²⁺ and Na⁺, while the dominant anions are HCO₃^- and SO₄^2- during both seasons. The hydrogeochemical plots, ionic ratios, and multi-statistical analysis suggest that rock weathering, ion exchange processes and human activity are the main factors influencing the chemical composition of Umaria coalfield groundwater. The high SO₄^2- concentration in the groundwater samples is primarily attributed to the oxidative weathering of pyrite, followed by gypsum dissolution, and can have an adverse impact on the human health in the study area. Agricultural practices and residential sewage cause a high NO₃^- concentration in some samples, which can harm the health of the population residing in these areas. The high values of TDS, total hardness (TH), nitrate, sulphate, fluoride, magnesium, calcium, and the water quality index (WQI) indicate that many groundwater samples require proper treatment before being used for drinking and domestic purposes.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In light of this, environmental assessment of such pollutants becomes urgent and necessary. In this study, we have investigated antibiotics in different point and non-point sources across Assam, India. A total of 16 samples were collected and analyzed via the HPLC-UV method for quantitation, followed by LC-MS analysis of positive samples for confirmation of analytes. The nature of samples ranges from various cattle farms, veterinary hospitals, sewage treatment plants, and water treatment plants to the Brahmaputra River and its tributary. Finally, the ICP-MS study was taken up for all 16 samples and was analyzed for 24 different elements. The analysis was done via an optimized and ICH-tripartite guideline-validated method. The highest concentration was of amoxicillin, 1216.98 μg/L. However, the highest frequency was of tetracycline and ciprofloxacin.

Urban greening is considered a potential solution to mitigate air pollution caused by BC particles, because atmospheric BC particles can be deposited and retained on the leaves of urban greening trees, resulting in a reduction in the atmospheric concentration of BC particles around the trees. However, there is no information on the variation in the amount of BC particles deposited on leaves at different positions in the canopy of mature urban greening trees throughout a year, its related factors, and the amount of BC particles on the entire canopy of a mature tree. The objective of this study was to investigate the amount of BC particles deposited on the leaves of mature trees of Cornus florida L. at different positions in the canopy and its related factors. The results indicated that there were significant differences in the amount of BC particles among leaf positions in June and July 2020. In and after July, a positive correlation was observed between the amount of BC particles deposited on the leaves and leaf surface traits, such as the amount of epicuticular wax. Consequently, the capacity to remove atmospheric BC particles varies with leaf position in the canopy of mature urban greening trees, primarily attributable to the variations in leaf surface traits. In addition, when the variation in the amount of BC particles deposited on leaves at different leaf positions in the canopy does not take into account, the total amount of BC particles in the entire canopy of a mature C. florida tree is 0.7-33% higher than the present assessment method, which takes this variation into account.
