TEM images and EDS spectra of individual primary particles from the combustion of cardboard, foam boxes, waste rubber tires, and plastic bottles/bags. (a) Low magnification TEM image of OM and S-rich-OM from cardboard in the flaming phase; (b) An irregular OM particle from cardboard in the flaming phase; (c) An S-rich particle internally mixed with OM from cardboard in the flaming phase; (d) A bare chain-like soot particle from foam boxes in the flaming phase; (e) Soot particles coated by thin OM from waste rubber tires in the flaming phase; (f) A soot particle coated by thick OM from plastic bottles/bags in the flaming phase. The corresponding EDS spectra are indicated by the number in square brackets.
