Short summary
We measured singlet oxygen (1O2*) and triplet excited states of organic matter (3C*) in illuminated aqueous extracts of PM2.5 collected in different seasons at different sites in Hong Kong SAR, South China. In contrast to the locations, seasonality had significant effects on 3C* and 1O2* production due to seasonal variations in long-range air mass transport. The steady-state concentrations of 3C* and 1O2* correlated with the concentration and absorbance of water-soluble organic carbon.
