This study first employed Sphagnum palustre moss bags as low-cost sentinels to monitor indoor polycyclic aromatic hydrocarbons (PAHs) across three university libraries differing in age and location. Moss bags were deployed for 45 days during the non-heating (autumn) and heating (winter) periods in study rooms, electronic reading rooms, stack rooms, and outdoors. Total PAH concentrations ranged from 487.20 to 1,049.86 µg/kg in autumn and 734.60 to 3,167.35 µg/kg in winter, with phenanthrene, naphthalene, pyrene, and fluoranthene as dominant congeners. Indoor-to-outdoor ratios indicated indoor sources at some sites in autumn, but outdoor infiltration in winter. Diagnostic ratios revealed petrogenic origins in autumn and mixed petrogenic/pyrogenic inputs in winter at the study room of older libraries, influenced by domestic heating. The levels, profiles, and sources of indoor PAHs varied with room function, building age and location, outdoor air quality, and season. These findings demonstrate that S. palustre moss bags are effective sentinels for detecting spatial and seasonal variations in indoor PAHs, offering a practical alternative for high-density indoor air quality monitoring.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"4264-4273"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149038455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The present study investigates improvements in wastewater treatment using an Intermittently Aerated Up-flow Constructed Wetland (IA-UCW). Two identical lab-scale UCW reactors were designed and operated, with one as a control and the other incorporating intermittent aeration. Experimental results revealed that the IA-UCW achieved enhanced wastewater treatment and supported similar plant growth to the control. Specifically, the aerated system achieved 78 ± 8% removal of TSS, 81 ± 4% of COD, 78 ± 12% of TN, and 64 ± 15% of TP, as compared to 59 ± 18%, 58 ± 13%, 17 ± 9%, and 26 ± 9% removal, respectively, in the control reactor. Dissolved oxygen showed a significant increase in the aerated system, with average Dissolved Oxygen (DO) values of 1.6 mg/L at 50 cm depth and 2.9 mg/L at 10 cm depth. Improved oxygen facilitated microbial activity and organic degradation, while promoting zones for nitrification-denitrification under intermittent on-off aeration. Plant growth study in both reactors enables harvest scheduling. Further, an intermittent aeration facilitated a reduction in footprint from 2.8 m2/PE to 0.9-2.1 m2/PE based on removal of organics and nutrients. These findings demonstrate the potential of IA-UCW as a wetland intensification strategy for land-constrained urban wastewater treatment.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"3666-3678"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148619987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Molecular identification was performed through 16S rRNA gene sequencing, and structural characterization of siderophores is ongoing using NMR and HRMS.

Converting this waste into value-added byproduct i.e., biochar offers a sustainable management approach to reducing the waste load on landfill sites and also guarding the nearby fauna, flora and water bodies. This study aimed to develop metal-resistant microbial consortium loaded biochar (MCLB) by inoculating tannery solid waste biochar (BC) with consortium of ten Bacillus and/or five Trichoderma strains and their effect was evaluated on the morphological and biochemical attributes of sunflowers including metals immobilization. The soil amendment with BC at 2% rate improved the shoot height, dry biomass, and chlorophyll content in sunflowers but not in higher doses. However, the application of MCLB even at its highest concentration i.e., 10% dose showed a significant increase in shoot length (61.2%) and dry weight (656.9%) over BC only. The findings of metal bioavailability indicated that the application of MCLB having metal-resistant strains decreased the mobility of Cd, Cr, Cu, Ni, Pb and Zn into the sunflower tissues compared to BC. Moreover, MCLB enhanced the uptake of Fe and Mg which are beneficial to the plant. In addition to that, the results for phenolic and proline content demonstrated a considerable decrease by MCLB indicating less stress response as compared to BC. Therefore, these findings highlight the potential of MCLB as a sustainable soil amendment for improving the growth attributes of oil-yielding sunflower varieties by using tannery solid waste biochar while decreasing the uptake of nonessential metals. By pyrolyzing the tannery solid waste into biochar, this approach contributes to a circular economy and environmental remediation practices.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"88-104"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144954068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The present work aimed to prepare a novel biochar from Eucalyptus Camaldulensis leaves (EC-biochar) for the effective removal of Cd2+ and Pb2+ cations, as representative heavy metals, from aqueous solutions. The adsorption performance of Cd2+ and Pb2+ cations by EC-biochar was assessed by varying different operating parameters (e.g. pH, temperature, EC-biochar dose, adsorption time, and adsorbate concentration). The maximum removal efficiencies of Pb2+ (83.8%) and Cd2+ (89.6%) ions were achieved at pH 4.5. The pseudo-second order and Langmuir isotherm models satisfactorily predict the adsorption of Pb2+ and Cd2+ cations onto EC-biochar. The negative values of ΔG° and ΔH° demonstrated that the adsorption process is spontaneously feasible and exothermic. It is also worth pointing out that the regeneration/reuse study revealed that the as-prepared EC-biochar maintained an excellent adsorption performance after five reuse cycles, demonstrating its suitable reusability.
