Abstract

Dust samples needed for the research was put at our disposal in great amount by the DKCE power station of Debrecen. In the station dust filtration of air takes place in more steps, which provides us strained of on the coarse filters in the range of 2000 μm to 10 μm, while between 10 μm to 1 μm on the fine filters. Those particles that manage to get across the filter system can be collected by the off-line washing of the turbine area. This fraction will contain fragments which are particular concern to human health as they can not only get into the lung but can attach to the alveoli. Dust sample collected in the city centre, nearby a railway station and a congested vehicular bridge contains all the contaminants that are imposed on the inhabitants of a typical big city. It is established from the size range distribution of samples collected from the coarse filters that almost 90% of the particles are under 63 μm. We determined the chemical composition of dust by using highly sensitive analytical methods after setting aside the most appropriate sampling and preparatory processes. By the side of the inorganic components, dust samples contain pollen and smut particles in higher amount, as well as spherules.
