The phase state and chemical composition of PM2.5 are pivotal factors that influence their pollution mechanisms. Nevertheless, there is a notable gap in our understanding of how chemical composition affects the phase state of PM2.5. To address this gap, we conducted an investigation into the influence of chemical composition on the phase state of PM2.5 in four prominent cities: Seoul, Seosan, Beijing, and Ulaanbaatar, spanning from 2020 to 2023. Our research has unveiled that the range in which PM2.5 can exist in liquid, semisolid, and solid states may exhibit variations contingent upon its chemical composition. By emphasizing the significance of aerosol chemical characteristics on the phase state, this study significantly contributes to our comprehension of how phase state and chemical composition underpin atmospheric pollution mechanisms. The results will be presented.
