Figure 9

TEM images and EDS spectra of individual primary particles from the combustion of printed circuit boards and copper-core cables. (a) Br-rich particles internally mixed within bubble-like OM (Sn, Sb) from printed circuit boards in the flaming phase; (b and c) Bubble-like OM (Sn, Sb) internally mixed with Br-rich, Pb-rich, P-rich and Zn-rich from printed circuit boards in the flaming phase; (d and e) Low magnification and high resoluton TEM images of OM-Br-soot particles from copper-core cables in the flaming phase. The corresponding EDS spectra are indicated by the number in square brackets. The Cu* peaks in the EDS spectra are not analyzed because of the interference from the copper TEM grids.
