Short summary

In this study, we found that the effective field-derived Henry's law constant for the ground rainwater and the gas-phase H₂O₂ was about 2.5 times that of the theoretical value, and the effective gas–particle partitioning coefficient for the aerosol particle and the gas-phase H₂O₂ was 4 orders of magnitude higher than the theoretical one. We suggested the missing source of H₂O₂ in the particulate phase, e.g. the contribution from the decomposition/hydrolysis of organic peroxides.
