In this context, lakes also have a negative impact related to the large amounts of water they can consume through evaporation. This paper quantifies the effects of a small artificial lake-Dridu from Romania (with complex usage) on the environment in the context of CC, estimating the blue water footprint (WF) and carbon footprint (CF) under different use scenarios. Thus, an analysis of the evolution of CF and WF is conducted until 2100, considering forecasts of changes in average temperatures, as well as a partial coverage of the lake's surface with floating photovoltaic systems (FPV). During the study period from 2017 to 2021, the average WF was 0.054 million m<sup>3</sup>, and the carbon intensity was 120.23 kg CO<sub>2</sub>e/MWh. By covering 2 ha of the reservoir's surface with FPV, the production and release of CO₂ and CH₄ into the atmosphere decrease, on average, by 30% for WF and 28.13% for CF. For the CC scenarios, it is observed that WF will increase by an average of 10.4%, while the carbon footprint shows no significant variations. It is worth mentioning that this type of approach, e.g., impact of FPV on WF and CF, as well as the use of FPV as a measure of coping with CC, has not been studied yet in any region of Eastern Europe. This study, given that it deals with relatively new technologies (FPV), has some gaps, since the CF is computed based on estimates, not on measured data. However, the results and the methodology currently presented can be used by various stakeholders to identify the best coping mechanism for preserving the water quantity and for generating clean energy. Also, these types of studies can be a good stimulus for the authorities to develop and permit the placement of FPV on small reservoirs and to investigate the effects of such projects in terms of energy, FPV efficiency, water quantity, and quality, as it will allow the actual quantification of different effects and benefits brought by this technology (water quality indicators, GHG emission, reduction of evaporation, FPV energy output).</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332263","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}

The development of a novel method for highly sensitive and specific detection of GPNMB is essential for PD's early and accurate diagnosis. An electrochemical biosensor was developed utilizing silver nanoparticle-loaded mesoporous silica (Ag@MSNs) with 4-mercaptophenylboronic acid (4-MPBA) modification for the sensitive and selective detection of GPNMB. MSNs were utilized as an excellent loading substrate for silver nanoparticles. 4-MPBA at the surface of Ag@MSNs can bind GPNMB specifically through the boronic acid group and multi-glycosylation sites of GPNMB. The finally prepared Ag@MSNs-MPBA exhibited a core-shell structure, which served as a highly efficient electrochemical signal amplifier and selective binding reporter. The enhanced electrochemical signal sensitivity was attributed to the output of the electrochemical signal of Ag through preventing the agglomeration of AgNPs and efficient capture of GPNMB by Ag@MSNs-MPBA. The analysis results demonstrated that the developed electrochemical sensor successfully detected GPNMB with an LOD as low as 0.9011 ng/mL (S/N = 3) in the detection range 1 to 100 ng/mL.

In semi-arid areas, this increased pressure has led to excessive use of agrochemicals in agriculture, which poses a threat of potentially toxic metal (PTM) contamination in agricultural soils. PTMs in agricultural soils result in significant environmental and health threats for humans and livestock. The current study aimed to evaluate the risks associated with five PTMs-nickel (Ni), lead (Pb), chromium (Cr), cadmium (Cd), and cobalt (Co)-in agricultural soils of the semi-arid South Punjab region of India. The study area included sites from district Bathinda of Punjab (3385 km<sup>2</sup>). Among the PTMs analyzed, the concentration of Cd (0.65-1.85 mg/kg) in several agricultural soil samples was above the international permissible limits (1.0 mg/kg). Principal component analysis (PCA) pointed to parent rock materials as the main sources for Cr, Co, Ni, and Pb, while for Cd, agricultural sources (phosphatic fertilizers) can be a prominent contributor. The values observed for Pollution Load Index (PLI: 0.93-1.64) and Ecological Risk Index (RI: 206.66-584.03) indicated that soil samples were significantly contaminated with the tested PTMs, posing considerable ecological risks. Analysis of other physicochemical characteristics showed that soil samples were alkaline and saline, with low levels of soil organic matter. The human health risk assessment pointed to minimal non-carcinogenic (NCR) and carcinogenic risks (CR) associated with the presence of PTMs in the soil. Spatial distribution analysis revealed a higher level of metallic contamination in the eastern part of the district.

This study investigated spatiotemporal variations in phycocyanin concentrations in East Lake, Wuhan, from March to September (2018-2022), using generalized additive model (GAM) with Landsat-8 imagery to assess changes before, during, and after the lockdown.

However, phycocyanin levels rebounded post-lockdown, with variations across sub-lakes, indicating that temporary reductions in human activity alone were insufficient for sustained water quality improvement. Further analysis showed that long-term conservation strategies played a decisive role in the continued water quality improvements observed in 2022.

The exercise group followed a 50-min 3 days/week moderate intensity concurrent exercise training program from the 16th gestational week until birth. Infant neuromotor skills were assessed with the Peabody Developmental Motor Scales, 2nd edition (PDMS-2).</p><p><strong>Results: </strong>Per protocol analyses showed that infants from the exercise group and whose mothers were normal-weight, had higher PDMS-2 Stationary, Locomotion (borderline) and Gross Motor Quotient (GMQ) percentiles than infants of stretching and breathing participants (p = 0.022, ηp2 = 0.20; p = 0.054, ηp2 = 0.15; p = 0.022, ηp2 = 0.20, respectively). No differences between groups were found in infants whose mothers were normal-weight in reflexes percentiles in the adjusted model, or those infants whose mothers were overweight/obese in any of the outcomes (all p ≥ 0.05).</p><p><strong>Conclusions: </strong>Concurrent exercise training during pregnancy improves neuromotor skills in infants at 1 month of age in normal-weight women. Further studies are needed to understand the influence of concurrent exercise training during pregnancy on infants whose mothers are overweight or obese, and the potential mechanism behind the role of maternal BMI in the development of infant neuromotor skills.</p><p><strong>Clinical trial registration: </strong>ClinicalTrials.gov Identifier: NCT03838146.</p>","PeriodicalId":21788,"journal":{"name":"Sports Medicine - Open","volume":"11 1","pages":"78"},"PeriodicalIF":4.1,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144336843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
