The mechanism and factors controlling the hygroscopicity of black-carbon-containing particles (BCPs) from different carbon sources are not well understood. We thoroughly characterized the chemical and compositional properties of 15 samples of BCPs from different sources (wood, herb, and soot) and further investigated their hygroscopicity. Depending on the carbon source, organic carbon and dissolved mineral contents were key determinants of the equilibrium and kinetics of water uptake by BCPs.
