Particulate Matter Concentration in Selected Facilities as an Indicator of Exposure to Their Service Activities.

In recent years, the correlation between the concentration of pollutants in the atmosphere and inside buildings has been reported as high. The air inside living quarters and public utility buildings or the interiors of public transport vehicles, as well as the relationship between the internal and external sources of particulate matter (PM) and gaseous pollutants, have underwent sufficient research. On the other hand, non-production rooms, i.

New insights into submicron particles impact on visibility.

The aim of the study was to analyze the impact of very fine atmospheric particles (submicron particulate matter; PM) on visibility deterioration. Taking into consideration not only their entirely different physio-chemical properties in comparison to a well-recognized PM but also the origin and a growing environmental awareness of PM, the main research problem has been solved in few steps. At first, the chemical composition of PM was determined in two selected urban areas in Poland.
