Organosulfate-driven amplification of secondary organic aerosol formation from isoprene oxidation intermediates: Coupled effects of SO2 and relative humidity

Puntos clave

• Increased secondary organic aerosol formation highlights the role of organosulfates in atmospheric chemistry, particularly under varying humidity levels.
• The formation of aerosols was significantly elevated in the presence of SO2, emphasizing its interaction with isoprene oxidation products.
• Evidence shows that both relative humidity and SO2 levels contribute to the complexity of secondary organic aerosol dynamics.
• Understanding organosulfate-driven pathways is crucial for predicting aerosol behavior and environmental impacts.
