Abstract
Industrial filter cakes and PM of atmosphere aerosols have been studied by combination
SEM and microprobe analysis. Salt water drops, micro-crystals, metallic spherules, pollen
and spores, small-sized insects were observed. Pollen, spores and industrial micro-particles
were the main objects of the investigation. Seasonal pollination calendars for pollen and
spores have been compiled. Pollen with morphological disturbances and mud on the pollen
surface, pollen infected by fungus spores, small-sized insects with mould colonies were
observed. These objects may be the indicators of the ecological deviation. Industrial PM and
filter cake matter of ferrous and non-ferrous metallurgy and glass industry of Belarus has
been studied.
