Internally mixed soot, sulfates, and organic matter in aerosol particles from Mexico City [PDF]
Atmospheric Chemistry and Physics, 2008 Soot particles, which are aggregated carbonaceous spherules with graphitic structures, are major aerosol constituents that result from burning of fossil fuel, biofuel, and biomass. Their properties commonly change through reaction with other particles or
