Cover Story: Despite firefighting being classified as carcinogenic to humans, the underlying biological mechanisms have yet to be fully understood. Comprehending firefighters’ occupational exposure across various settings and time points of their activity is crucial. We characterized firefighters’ occupational exposure to particulate matter in fire stations prior to the wildfire season in the Northern region of Portugal. The biological impact of estimated inhaled doses of PM10 and PM2.5 (indoor/outdoor) was accessed through buccal micronucleus cytome assay in exfoliated buccal cells. Our findings provide the essential baseline for further studies assessing exposure during the wildfire season, highlighting the importance of biomonitoring programs to identify individuals predisposed to adverse health outcomes.
