Plastic pollution is one of the leading global problems of modern society. The growing demand for and production of plastic polymers has caused bisphenol A (BPA) and its emergent substitute molecules bisphenol S and F (BPS and BPF) to be present in water, food, and soil worldwide, exposing humans to endocrine disruptors. Exposure to these compounds has been associated with pathologies such as diabetes, obesity, hypertension, and psychiatric disorders. Interestingly, hypovitaminosis D (or low 25(OH)D) is also associated with this class of diseases. Therefore, the present work, for the first time, explores the relationship patterns between urinary bisphenols (BPs) and low 25(OH)D in a large general cohort (NHANES 13–16). Descriptive statistical analyses, comparative analyses, linear regressions, and binomial and multinomial logistic regressions were performed. Descriptive and comparative analysis, and simple linear regressions, showed different trends between BPs, and binomial logistic regressions showed that only BPS is a risk factor of low 25(OH)D, independently of age, BMI, gender, diabetes, dyslipidemia, smoking, and vitamin supplements consumption; odds ratio (95% confidence interval) of 1.10 (1.04–1.17). The different trend patterns observed in urinary bisphenols show that, despite being structurally similar molecules and potential analogs, they may affect the body in different ways. From an integrated perspective, this could represent an even greater potential threat than that posed by BPA alone. Future integrated studies will be required to further explore and clarify this emerging paradigm. Full article

Introduction: Ecological networks (ENs) are critical frameworks designed to protect biodiversity, enhance habitat connectivity, and provide ecosystem services in fragmented landscapes. Urban ecological networks (UENs) adapt this concept to address the challenges posed by urbanization, habitat fragmentation, and climate change. Methods: This systematic review follows the PRISMA methodology, with the search strategy applied across PubMed, Scopus, and Web of Science. Articles published until 29 July 2025, were evaluated based on their alignment with One Health domains: human, animal, and ecosystem health. The included studies underwent independent review and quality assessment using the Newcastle–Ottawa Scale. Results: Only nine of the 228 articles that were found satisfied the requirements for inclusion. These studies examined UENs’ effects on biodiversity, species migration, and climate resilience but lacked direct evaluation of human health impacts. Key findings highlighted the role of ecological corridors in improving habitat connectivity, promoting biodiversity, and mitigating climate-related fragmentation. Conclusions: While UENs show significant potential to enhance biodiversity and urban resilience, their direct impacts on human health remain underexplored. Future interdisciplinary research should focus on quantifying these links and integrating UENs into urban planning to address ecological and Public Health challenges under a One Health framework.

Safe and adequate water supply, sanitation, and hygiene (WASH) in schools are prerequisites within the right to basic education. WASH facilities across schools in developing nations, particularly in Africa, are unsatisfactory and expose children to risks of disease and infection. This study aims to gather insights into the WASH status of secondary schools in Ibadan, Nigeria, to develop a sustainable water management framework for schools. A concurrent mixed-method design (questionnaires and interviews) was adopted to benchmark water management in schools and inform the design of a framework. Results reveal a wealth of issues and concerns that include infrastructure challenges accessing reliable and safe water supplies, rundown and unhygienic toilet/urinal facilities, and dilapidated sinks/taps, plus resource challenges, such as an absence of tissue paper and soap. These issues are exposing schoolchildren to unnecessary health risks, further supported by reported illnesses and reduced school attendance. Based on these findings, and guided by the UN SDG#6 targets, a water improvement framework has been created and validated by school officials. The framework identifies both short-term and long-term guidance/actions to improve water management in schools across Sub-Saharan Africa. These form crucial steps toward better WASH, building healthier communities and enhancing educational environments and outcomes for schoolchildren. Full article

The relationship between natural environments and psychological well-being has gained increasing attention in environmental and health sciences. However, there is still a lack of robust quantitative instruments to assess the restorative potential of different environments. This study aimed to adapt and validate the Portuguese version of the Perceived Restorativeness Scale (PRS), an instrument based on Attention Restoration Theory that evaluates the perceived restorative qualities of environments. In Study 1, exploratory and confirmatory factor analyses were conducted on data from 410 participants. The results supported a refined 20-item version of the scale, comprising four factors—being away, fascination, compatibility, and legibility—with good internal consistency and acceptable model fit. Measurement invariance analysis confirmed configural, metric, and scalar invariance across gender. In Study 2, a separate sample of 212 participants completed the PRS along with additional validated measures: the Sublime Emotion toward Nature Scale (SEN), an aesthetic evaluation of landscapes, and the Positive and Negative Affect Schedule (PANAS). The PRS showed strong convergent and discriminant validity and significantly predicted restorative outcomes. These findings support the psychometric adequacy of the Portuguese PRS and its relevance as a valid tool for assessing perceived restorativeness in both natural and built environments. The scale may inform future research and public policies aimed at designing spaces that promote psychological restoration and mental well-being. Full article

Background: The associations between physical activity (PA) and all-cause mortality remain under-investigated among individuals with impaired lung function. Methods: With 201,596 participants from the UK Biobank cohort, baseline pre-bronchodilation lung function tests and a modified International Physical Activity Questionnaire were used to assess lung function status (normal, restricted, obstructed) and PA attributes (volume, intensity, duration). All-cause mortality was determined through linkage to the National Health Services Register. Cox proportional hazard regression was applied to characterize the associations between PA metrics and all-cause mortality among people with different lung function statuses. Dose–response relationships between PA metrics and all-cause mortality risks were examined using restricted cubic splines (number of knots = 4). Results: Over a 11.81-year median follow-up, 5.24% of participants died. All-cause mortality risk declined with increasing total PA volume, plateauing at 1800 MET-min/week without further reduction in individuals with and without impaired lung function. Similar trends were observed for PA intensity and duration, with both factors demonstrating reduced mortality risk that plateaued after reaching a specific threshold. Notably, 24.1% (95% CI: 16.7%, 30.8%) and 43.1% (95% CI: 36.1%, 49.7%) lower mortality risk was observed among individuals with and without impaired lung function for PA with 1201–1800 MET-min/wk. Conclusions: PA was associated with a decreased risk of all-cause mortality among individuals with and without impaired lung function, suggesting that those with impaired lung function might also benefit from PA.

The aim of this research was to develop and validate a framework capable of enhancing the management of ballistic waste considering the context of the training activity of a Public Security Institute in Belém do Pará. A literature review was adopted as a method to provide the theoretical basis necessary to understand the context and develop the proposed conceptual framework, a questionnaire was developed and applied to security professionals, and the data were analyzed using the Lawshe-TOPSIS hybrid approach to validate the framework. The results make it possible to present, in an organized manner, a set of variables considering challenges and benefits for a framework for ballistic waste management. It is possible to conclude that ballistic waste management, especially in environments such as shooting ranges, is configured as a multifaceted challenge that demands a highly complex technical, normative, and operational approach.

Municipal Solid Waste Incinerators (MSWIs) are facilities designed to burn municipal solid waste to reduce its volume and mass and generate energy. A significant concern related to MSWIs is the emission of toxic and carcinogenic pollutants, including polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), heavy metals, and particulate matter. This review synthesizes global epidemiological and exposure assessment studies investigating cancer risks associated with residential proximity to MSWIs. Findings reveal a complex relationship: older incinerators with high emissions correlate with elevated risks of non-Hodgkin lymphoma (NHL), soft-tissue sarcoma (STS), and liver cancer in some studies, particularly in Europe. However, results remain inconsistent due to methodological limitations such as exposure misclassification, latency periods, and confounding factors like socioeconomic status. Modern facilities equipped with advanced pollution control technologies demonstrate reduced risks, often within regulatory thresholds. Key challenges include accurately quantifying historical exposures and disentangling MSWI-specific risks from other environmental or lifestyle factors. While advancements in dispersion modeling and biomonitoring have improved risk assessments, geographical and temporal variations in findings underscore the need for continued research. The review concludes that while historical evidence suggests potential cancer risks near older MSWIs, stricter emissions regulations and technological improvements have mitigated health impacts, although vigilance through long-term monitoring remains essential to safeguard public health.

Urban vegetation plays a key role in promoting health and environmental balance in cities. This study analyzed the relationship between green areas and human well-being in the Alvorada neighborhood of Guanambi, Bahia, Brazil. Using an ecological study design, vegetation was assessed through the Vegetation Coverage Index (VCI), percentage of vegetation coverage (PVC), aerial and satellite imagery, and population density data. Field visits were also conducted to validate remote observations. The results revealed that the VCI in the study area was significantly below the levels recommended by the World Health Organization (12 m²/inhabitant), indicating a scarcity of green areas. This deficiency is associated with reduced thermal comfort and potential negative impacts on residents’ physical and mental health. The findings reinforce the urgent need for sustainable urban planning in alignment with Sustainable Development Goals (SDGs) 3, 11, and 13, highlighting vegetation as a determinant of urban quality of life.

The study aims to identify key features in the built environment that are associated with heat-related health risks among older people in high-income countries, which could inform the development of targeted interventions to reduce built-environment-related heat risks for older populations in the context of climate change. We conducted a systematic review to identify features of the built environment associated with the health impacts of heat amongst people aged 65 or over, living in urban areas. Three databases, PubMed, Scopus, and Web of Science, were searched for the period from database inception until February 2025. The key built environment features associated with adverse health outcomes among older people included urban land surface vegetation, impervious ground surfaces, orientation of bedrooms, top floor locations of apartments, housing age, and the presence and use of air conditioning. The health indicators used in this study were heat-related mortality and morbidity represented by hospitalisations and ambulance call-outs. Built environment features were significantly associated with heat-related health risks among older people. Given the increasing high temperatures and more frequent and intense heatwaves in the context of climate change, there is an urgent need to develop targeted built environment adaptation plans for older people to strengthen their resilience to heat and reduce heat-related adverse health impacts.
