Summary

Epidemiological research has shown that exposure to particulate matter has been linked to adverse health effects. The present study aims at reporting the initial findings of an experimental campaign that was held in private residences in Athens with different degrees of urbanization and environmental conditions. Measurements include particulate matter concentrations (TSP, PM10, PM2.5, PM1) and Ultrafine Particles (UFP). The experimental campaign was performed for over a month in a typical urban apartment and a suburban detached house under normally occupied conditions. First results indicate that PM concentrations in the urban area significantly exceeded those of the suburban case under all operating and environmental conditions. In many cases where thresholds exist, particulate matter concentrations in the apartment exceeded the limit values. Occupants’ presence and indoor activities such as smoking, cooking cleaning etc. influenced the diurnal variation of particle concentrations. During the night the indoor pollutant sources ceased and the concentrations of certain particle sizes decreased. Power spectrum analysis was used to identify periodicities and trends of particulate matter concentrations. Spectral density comparison was also performed for particles in various size ranges as well as for particles of the same size in the studied residences. This is a preliminary study on the indoor environment in private residences in which the processed results of initial data are presented. However measurements are ongoing and several additional parameters are being recorded.
