The highest annual mean PM2.5 (29.9 ± 19.4 µgm−3), PM10 (55.8 ± 37.8 µgm−3) in 2022, and PM2.5 (21.4 ± 7.8 µgm−3) and PM10 (41.1 ± 14.8 µgm−3) in 2021 were reported in Jaffna and Kurunegala, respectively. Throughout both years, the PM concentrations were always higher than the World Health Organization guidelines. Seasonally, the Northeast monsoon experienced the highest average PM2.5 (54.7 µgm−3) and PM10 (104.2 µgm−3) in 2022, which may be attributed to low rainfall (∼4.5 mm), moderate temperature (∼26°C), and low wind speed (∼3 mph). The conditional bivariate probability function (CBPF) revealed probable sources to be motor vehicles (in Colombo, Galle, and Kurunegala), biomass burning (at all sites), textile units (in Colombo, Kurunegala), cement manufacturing plants (in Galle, Puttalam), and coal-fired power plants (in Puttalam). A period of 72-hr backward trajectories at 500, 1000, and 1500 m using the hybrid single-particle Lagrangian–integrated trajectory (HYSPLIT) revealed air mass pathways tracing back to eastern India and the Bay of Bengal, confirming transboundary pollutant movement into Sri Lanka. The health effects of PM2.5 exposure were estimated via AirQ+, which revealed the highest mortality in Jaffna in 2022.

This study evaluated the effectiveness of filter cake biochar (FCB) in remediating Cd-contaminated soil and mitigating its transfer to vegetables. A greenhouse experiment was conducted using an Ultisol contaminated with 10 mg kg−1 Cd. Four vegetables, Swiss chard (Beta vulgaris), okra (Abelmoschus esculentus), beetroot (B. vulgaris), and bell pepper (Capsicum annuum), were cultivated in pots with and without FCB amendment. FCB application reduced Cd availability in soil, from 4.5 to 0.5 mg kg−1, bringing concentrations below the regulatory guideline (1.3 mg kg−1). This was accompanied by a reduction of up to 87% in Cd concentrations in plant tissues. Improvements in soil fertility were also observed, including increased pH, organic carbon, and availability of P, Ca, Mg, Fe, and Mn. Cd accumulation in plant tissues varied by species, with bell pepper showing the lowest and Swiss chard the highest concentrations. Crucially, only vegetables cultivated in FCB-amended soil yielded edible produce, underscoring the biochar's role in mitigating phytotoxicity and enabling safe consumption. In addition to lowering Cd uptake, FCB enhanced biomass and nutrient accumulation in shoots. Correlation analysis confirmed strong positive relationships between soil fertility parameters and plant nutrient uptake, and negative correlations between Cd availability and plant performance. These results demonstrate that FCB is an effective strategy for reducing Cd risks in contaminated soils and improving the productivity and safety of vegetable crops.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 10","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clen.70052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the responses of SWC and SOC to vegetation restoration as well as their coupling interaction is important for the sustainable restoration of vegetation. However, the responses of SWC and SOC are still unclear in different plantation types, especially for the deep soil layer. In this study, three common types of mature plantations containing Pinus sylvestris, Pinus tabuliformis, and Populus simonii were selected in the Loess Plateau region of China to evaluate the responses of SWC and SOC to vegetation restoration as well as their interactions, and thus determine the factors that influenced the variations in SWC and SOC. Compared with grassland, the deep soil water deficit was exacerbated in all three plantations, and the SOC increased under Populus simonii but decreased under the other types. The tradeoff relationship between SOC and SWC had the lowest root mean squared error under Populus simonii. Therefore, Populus simonii was identified as most suitable for revegetation in the study region. Soil texture had important effects on the variations in SOC in the deep soil layers (2–5 m), and SOC and the soil texture affected the variations in SWC in the whole soil profile.

The objectives of this study were to: (i) develop random forest (RF) and artificial neural network (ANN) models for predicting and mapping the nitrogen content (%) in rice using seven vegetation indices derived from UAV multispectral sensors and; (ii) assess the key vegetation indices (VI) and their interrelationships with the predicted nitrogen content. Experiments were conducted at two locations in Cuttack district of Odisha, India, with different nitrogen levels. The UAV images were collected synchronizing with the maximum tillering stage of rice and seven indices were generated. The rice sampling was done on the date of flying UAV images and nitrogen content was estimated in the laboratory. RF and ANN models were developed using the N content as dependent and the VIs as independent variables. Both the models exhibited robust predictive capabilities, however, the RF model exhibited better performance, compared to the ANN model. Nitrogen content prediction using the developed RF and ANN models in testing site at farmer's field ranged from 0.78% to 1.95% (R2 of 0.67%) and from 0.5% to 1.78% (R2 of 0.55%), respectively.

This article deals with an experimental study to evaluate the shadow effect on the conventional solar still (CSS) performance. A comparative analysis was conducted between the single-slope CSS and the modified one (modified solar still [MSS]) with three glasses. Therefore, outdoor experiments were performed in hot and cold weather conditions in Adrar—Algeria. The results showed that replacing wooden walls with transparent glass is not always efficient, and the still's thermal performance depends on the weather conditions. On the summer day, the daily productivity reached 3.57 kg/m2 for the CSS and 4.42 kg/m2 for the MSS (a reduction of about 24% compared with the MSS). On the winter test day, the glass side walls appeared to negatively impact the MSS distillate yield, which was 5.55% lower than the CSS yield (2.57 vs. 2.71 kg/m2 for CSS).

The system allows the metabolic waste of fish and the unconsumed feed to be converted by a bacterial population into mineral nutrients that are used by the plants in the LW. For this purpose, the pond water was recirculated through a 7.2 m2 LW planted with 11 different ornamental plant species. The objectives of the study were (1) assessing the performance of LW vegetation irrigated with water from a pond and (2) monitoring the pond water quality with the LW used as a biofilter. The evolution of vegetation growth was monitored for 1 year by image analysis, and the concentration of some nutrients in the water was determined pre- and post-coupling. Vegetation cover increased from 30% to almost 100% after 1 year. Iron, magnesium, and nitrogen content increased in the LW plants after coupling with the pond. Electrical conductivity increased slightly with time, keeping below 500 µS cm−1. Nitrates, nitrites, and phosphates in the water were significantly reduced after the pond was coupled with the LW. Overall, the combination of both systems proved to be successful, optimizing the use of water and fertilizers with a circular economy focus.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 10","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clen.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we explored the effect of common anions (Cl−, SO42−, NO3−, HCO3−) in the concentration range of 1–100 mM on the kinetics of degradation and mineralization of ceftriaxone (CEF) by Far-UVC/H2O2 process using excilamp in synthetic (deionized water + anions) and real (tap) water. Nitrate at 1 mM and other anions at all concentrations exhibited a promotion effect by accelerating the degradation rate. It can be attributed to the contribution of secondary radicals generated by anions under Far-UVC exposure. However, the mineralization in terms of total organic carbon (TOC) removal decreased in the presence of HCO3− and NO3−. When reducing the H2O2 dose, chloride ions provided significant process intensification by increasing the rate constant by 3.5 times and reaching 30% TOC removal along with complete CEF degradation. Examining tap water revealed the high performance of the Far-UVC/H2O2 process for degrading and mineralizing CEF without the inhibition effect of matrix components. Results demonstrate that anions as radical precursors tend to promote the oxidation processes rather than inhibit them.
