TEM images and EDS spectra of individual primary particles from the combustion of wild grass. (a) Low magnification TEM image of the gel-like OM in the smoldering phase; (b) Low magnification TEM image of a mixture of OM and soot-OM in the flaming phase; (c) Two irrugualr OM and one internally mixed with soot in the flaming phase; (d) Two Cl-rich particles with thin OM coating and one internally mixed with soot in the flaming phase; (e) An irregular Cl-rich particle internally mixed with OM and soot in the flaming phase. The corresponding EDS spectra are indicated by the number in square brackets.
