- Biomonitoring of wildfire emissions exposure among firefighters during active fire missionsPublication . Barros, B.; Paiva, A.M.; Azevedo, R.; Alves, Sara Elisa Brás;; Esteves, F.; Fernandes, Adília; Vaz, Josiana A.; Slezakova, K.; Pereira, M.C.; Costa, S.; Almeida, A.; Teixeira, J. P.; Oliveira, M.; Morais, S.The aim of this study was to conduct a multidisciplinary biomonitoring assessment of the exposure and health impacts of wildfire emissions on firefighters from the Northern Portugal, one of the regions most affected by wildfires. Firefighters from fourteen fire stations participated in pre- and post-exposure sampling campaigns during two consecutive years. Self-reporting biometric characteristics, lifestyle, clinical information, career years, environmental/occupational exposure along with urinary biomarkers of polycyclic aromatic hydrocarbons metabolites (OHPAHs), metal(loid)s [from the priority pollutant lists compiled by the Agency for Toxic Substances and Disease Registry 14, United States Environmental Protection Agency 11, and the Human Biomonitoring for Europe Initiative priority 4], lung injury, lipid peroxidation, DNA damage, blood pressure, cardiac frequency, and hemogram were evaluated (Barros et al., 2025; Esteves et al., 2025; Paiva et al., 2024a; Paiva et al., 2024b). Stronger correlations were found between OHPAHs and metal(loid) levels and effect biomarkers after wildfire combat in comparison to pre-exposure. Wildfire exposure increased urinary -smokers. For the latter, copper, cadmium and barium ions correlated with lung injury; antimony and cadmium correlated with lipid peroxidation; DNA oxidation correlated with antimony, cadmium, copper, lead, zinc, selenium, and rubidium levels. Moreover, arsenic, antimony, lead, and copper induced lipid peroxidation, and lead was linked with DNA oxidation among wildfire-exposed smokers. Significant positive correlations were found for age and/or career length with cadmium, lead, barium, strontium, and mercury, and for body mass index with arsenic. These results point to an increased risk of health effects both in non-smoking and smoking firefighters because of their occupation, highlighting the necessity to strengthen prevention strategies.
- Particulate matter exposure and cardiovascular risk a reviewPublication . Alves, Sara Elisa Brás; Vaz, Josiana A.; Fernandes, Adília; Molés, P.Exposure to particulate matter is a growing public health concern due to its strong association with respiratory and cardiovascular diseases (World Health Organization, 2022). Firefighters face a significant cardiovascular risk due to repeated exposure to particulate matter from smoke, ashes, and combustion by-products (Fabian et al., 2014), combined with disrupted sleep, physical-emotional strain, and extreme heat (Bralewska et al, 2024). Most research only focuses on acute events during active firefighting, neglecting the long-term effects of chronic particulate matter exposure on their cardiovascular health (Esteves et al, 2024). This study reviews the association between long-term occupational exposure to particulate matter and cardiovascular risk in firefighters. A literature search was conducted using recent publications indexed in PubMed, CINAHL, Cochrane and Web of Science. Literature in English, published from January 2015 to December 2025, was included. Research after the World Trade Center disaster found a strong link between higher exposure levels to particulate matter and increased cardiovascular events like heart attacks and strokes, even after adjusting for traditional risk smoke significantly raises the lifetime risk of cardiovascular disease, with risks increasing with career length and incident frequency (Navarro et al, 2019). There is also evidence of a dose-dependent relationship between firefighting exposure and atrial fibrillation, indicating the combined effects of inhaled pollutants and occupational stress (Vanchiere et al, 2022). Short- porary blood pressure spikes, while chronic exposure contributes to sustained hypertension (Clementi et al, 2019). These findings emphasise the causal role of particulate matter exposure in cardiovascular issues and highlight the need for long-term monitoring and preventive measures for high-risk groups like firefighters. Future research should focus on addressing the gaps in long-term monitoring and exposure assessment to better understand cardiovascular risks associated with particulate exposure.
