Abstract

Aerosol pH is an important parameter that affects air quality, and the health of aquatic and terrestrial ecosystems. However, the lack of such data was reported in Ho Chi Minh City (HCMC), Vietnam. In this study, we estimated the aerosol pH in fine particulate matter (PM2.5) collected in HCMC, Vietnam using the thermodynamic equilibrium models (E-AIM Extended Aerosol Inorganics Model and ISORROPIA-II), and the phase partitioning of ammonia. Aerosol pHs estimated by different methods were 1.7 – 2.9. Good correlations between the phase-partitioning approach and models in predicting the aerosol pH were observed with R2 from 0.77 to 0.89, suggesting that the assumption of equilibrium is valid at the HCMC site.
