KAUST researchers found that wildfire smoke particles act as chemical factories under sunlight, producing harmful oxidants like peroxides. These particles bypass traditional suppression by nitrogen oxides in polluted environments, generating oxidants internally. The study reveals that colored organic molecules in biomass-burning aerosols act as photosensitizers, triggering rapid reactions. Why it matters: The findings highlight that current air-quality and climate models underestimate oxidant production from wildfires, with implications for anticipating health risks and environmental impacts in regions like Saudi Arabia.
