- Chemical safety in academic laboratories: awareness, attitudes, and practices among higher education studentsPublication . Ribeiro, Inês; Ramos, Catarina; Santos, Joana; Carvalhais, Carlos; Santos, Joana; Alberto Alves Carvalhais, CarlosHigher education institutions, particularly those with teaching and research laboratories, play an important role in transmitting knowledge and attitudes regarding chemical safety to their students. As such, this study aims to assess the knowledge and attitudes of higher education students across different study programs regarding laboratory chemical safety. A cross-sectional study was conducted using a questionnaire adapted and translated into Portuguese. The instrument comprised twenty-seven questions and was distributed to students enrolled in undergraduate and graduate programs that include laboratory practices in their curricula in March and July of 2025. A total of 284 students participated in the study, divided among the different study programs (CTeSP = 4.2%; Bachelor’s = 70.4%; Master’s = 21%; Doctorate = 4.2%). The results showed that, although a large percentage of students have a high level of knowledge, their attitudes are not always the most appropriate, which could jeopardize their safety and that of those around them. Our findings revealed that there is room for curriculum adjustments. Early exposure to chemical and laboratory safety concepts can promote the development of students’ awareness and future professionals’ competence. Integrating safety modules into education may enhance knowledge and skills for making informed decisions that reduce accidents/incidents in laboratory environments.
- Occupational exposure to solar ultraviolet radiation: A systematic review of protective measuresPublication . Rocha, Ricardo; Santos, Joana; Baptista, João Santos; Guedes, Joana; Carvalhais, Carlos; Alberto Alves Carvalhais, Carlos; Santos, JoanaSolar ultraviolet radiation (UVR) is classified as a Group 1 carcinogen and poses a significant occupational hazard to outdoor workers. Despite preventive guidelines, adherence to protective measures remains inconsistent. This systematic review identified the protective measures adopted by healthy outdoor workers and assessed their adherence to and the effectiveness of these measures. Following the PRISMA 2020 statement, the review searched Scopus, Web of Science, and PubMed for peer-reviewed studies published between 2015 and 2025. Eligible studies included at least 100 healthy participants and evaluated preventive or protective measures against solar UVR. Independent reviewers extracted data and assessed risk of bias using the McMaster Critical Review Form. From 17,756 records, 51 studies met the inclusion criteria after screening and a subsequent snowballing process. The identified protective strategies clustered into physical, behavioural, and organisational categories. Adherence ranged from low to moderate, with structured interventions and employer support improving compliance. Sunscreen use remained low due to perceived inconvenience and lack of provision. Overall, the evidence revealed substantial variability in implementation and effectiveness across occupations. Strengthened regulations and integrated interventions combining education, personal protective equipment, and organisational measures are essential. Future research should prioritise longitudinal designs and objective indicators such as biomarkers and dosimetry.
- A systematic review of the health effects of occupational exposure to ultraviolet radiationPublication . Rocha, Ricardo; Guedes, Joana; Santos, Joana; Carvalhais, Carlos; Alberto Alves Carvalhais, Carlos; Santos, JoanaOutdoor workers face significant health risks from prolonged exposure to solar ultraviolet radiation (UVR), which can lead to serious conditions such as skin cancer and cataracts, while also offering some potential benefits like reduced risks of certain cancers. This systematic review synthesizes findings from 16 studies, revealing a clear association between occupational solar UVR exposure and adverse health effects, underscoring the urgent need for improved sun protection policies and further research to enhance risk assessment and prevention strategies.
- Unveiling stress vulnerability and occupational noise perception as burnout predictors: Results of an exploratory study in industrial environmentsPublication . Carvalhais, Carlos; Alberto Alves Carvalhais, Carlos; Ribeiro, Luísa Antunes; Pereira, Cristiana C.Burnout is a complex phenomenon influenced by both environmental and individual factors. This pilot study explores the predictive role of occupational noise perception and stress vulnerability on burnout symptoms among industrial workers. A cross-sectional survey was conducted with 119 Portuguese workers exposed to occupational noise. Participants completed validated self-report measures assessing noise perception, stress vulnerability, and burnout. Path analysis revealed that both higher stress vulnerability and greater perceived occupational noise were significant predictors of elevated burnout levels. Furthermore, gender emerged as a relevant predictor, with women reporting significantly higher burnout symptoms than men. Age was inversely related to stress vulnerability, indicating greater resilience among older workers. These findings suggest that individual differences in stress vulnerability and noise perception contribute meaningfully to burnout risk, beyond traditional occupational hazard assessments. The study underscores the need for holistic occupational health strategies, integrating both environmental modifications and psychosocial interventions aimed at enhancing workers’ coping capacities. This study contributes novel insights into the interplay between perceived noise and psychological vulnerability in industrial settings, supporting broader preventive measures for work-related mental health outcomes.
