Size-fractionated chemical fingerprints and health risks of biomass burning aerosols at the Thailand-Myanmar border

Key Points

• Biomass burning aerosols show significant health risks, especially linked to fine particulate matter.
• Chemical fingerprints indicate distinct compositions of aerosols collected across size fractions, with PM2.5 as a major concern.
• Analysis across various sampling locations highlights the prevalence of respiratory effects linked to exposure to biomass burning.
• Health risks detail the urgent need for mitigation strategies to protect communities affected by biomass burning.
