    AnotaceThe properties of individual particles, rather than bulk aerosol characteristics, determine the environmental and health impact of the atmospheric pollutants. Single particles have been sampled during 30 fog episodes at the mount Milesovka (837 m a.s.l.) located in the industrially polluted area of north Bohemian brown coalfield. More than 2000 of these solid, water insoluble particles, collected from May 2006 till July 2007, have been analyzed by SEM-EDX and classified according to their shape, size and elemental composition. Here we summarize results related to the presence of some heavy metals and other trace elements and their correlation to wind speed and direction, at given meteorological conditions. Particles, rich of Cu, Zn, Ba, Pb, Co, Ni, Fe, Ag, Au, Ce, Gd, etc., have been detected. Most of the identified heavy metals present in particles smaller than 5 mu m. It has been established that some elements exist separately or in specific combinations that, along with the information for particle's backward trajectory, could be used for recognition of the atmospheric pollution sources.
