The basic form of pollution is characterized by a microscopic size and solid state and it is called particulates or particulate matter. Uunfortunately, these forms undergo a variety of transformations, which consequently can sometimes be easily modified and even cause an increase in their toxicity. This work was devoted to join the composition of various materials being residues after different combustion processes with the distribution of elements and molecules within studied surfaces. The content of chosen elements was determined using ICP-MS and ICP-OES methods. Elemental and/or molecular distribution was studied using surface sensitive techniques, SEM-EDS and ToF-SIMS. The obtained results revealed that the composition and morphology of particles are strongly influenced by the type of material and combustion conditions.
