Wildfire smoke represents an underrecognized yet potentially important contributor to the dissemination of antimicrobial resistance (AMR). As wildfires increase in frequency and intensity due to climate change, they release vast amounts of PM 2.5 , particles with the potential to transport antimicrobial-resistant microorganisms and genetic elements across long distances. These severe air pollution events create multifactorial...

Air pollution remains a persistent environmental and public health concern in urban regions. This study presents a 22-year analysis (2001–2022) of coarse particulate matter (PM 10 ) concentrations across 15 monitoring stations in the Porto Metropolitan Area (PMA), Portugal. The stations, pre-classified by national authorities as traffic, background-urban, background-suburban, or industrial, were used to assess long-term tempor...
