In years 2006-2010 particulate matter analysis was undertaken for dust samples collected from Gdansk and London area in orderto compare their morphology and composition. Part of those studies was devoted to analysis of particulate matter (PM) bearingmetals. Characterization of the morphology and size of the particles collected onto the filters was performed using a scanning electronmicroscope (SEM) and transmission electron microscope (TEM). Both electron microscopes were equipped with energy dispersiveX-ray spectrometers to identify the elemental composition of the particles. On analysis of the X-ray spectra acquired by both TEM andSEM, the particles were divided into 10 groups as follows: Al-rich, Ba-rich, C-rich, Ca-rich, Cl-rich, Fe-rich, Mg-rich, Na-rich, S-rich,Si-rich. Speciation of the particles based on the major element and accompanying minor elements yielded 34 particle types. However,some pairs of elements repeat, for instance: Na-Cl and Cl-Na, Al-S and S-Al, Si-Al and Al-Si, S-Ca and Ca-S. These are undoubtedly thesame types of particles; variation in peak heights of the major and minor elements is normal in a mixed particle population.
