Abstract

After photolysis, more acidic particles show an increase in pH, while the more neutralized particles show a decrease in pH. NO3− and MEA decay rates are more sensitive to the initial pH than RH. Water-soluble BrC and an organic phase were formed as potential secondary organic aerosols (SOAs).
