Short summary
This study provides comprehensive insights into the compositions, surface elements, and formation mechanism of BrC in the atmosphere of Dhaka, Bangladesh, through the identification and quantification of seven key phenolic precursors and a laboratory-based aqueous-phase nitration experiment. We observed that PM2.5 particles predominantly exhibited spherical, irregular, and chain-like morphologies, with carbonaceous species, minerals, and trace elements.
