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.
