Figure 7

TEM images and EDS spectra of individual primary particles from the combustion of cypress, pine, and pear wood, and bamboo. Low magnification and high resolution TEM images of (a and b) irregular OM-soot particles from cypress wood, (c and d) OM-K particles from pine wood, (e and f) bare cluster-like soot particles from pear wood, and (g and h) cluster-like soot particles internally mixed with KCl and spherical OM from bamboo, in the flaming phase, respectively. The corresponding EDS spectra are indicated by the number in square brackets.
