Resumo(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.
