Short summary
In this study, we analyzed the mixing state and atmospheric chemical processes of Pb-rich single particles in Beijing. We focused on analyzing the differences in Pb-rich particles between the heating period and non-heating period, as well as the formation mechanism of lead nitrate after coal-to-gas conversion. Our results highlighted the improvement of Pb levels in the particulate as a result of coal-to-gas conversion.
