4. CONCLUDING REMARKS
The indoor air quality of two differently used areas, a residence and two offices was
assessed during two experimental campaigns performed and the data obtained were very
interesting. It seems that the indoor and outdoor air quality of the residence is poor and
that the location plays the primary role, i.e., it is a residential area where all buildings use
petrol central heating, close to a heavy trafficked road and surrounded by pine trees.
Furthermore, total VOCs and CO2 concentrations in the residence were significantly
higher than in the office which may be attributed to the type of activities that took place by
the inhabitants, especially cooking and cleaning and the longer time they occupy their
home. It seems that deposition of VOCs on the walls is another important process since
at night time in the kitchen they maintained their high levels indicating re-emission after
the end of cooking. On the other hand the offices had better indoor and outdoor air quality
regarding the classical pollutants and TVOCs and CO, CO2 since the university campus
is located at a distance from inhabited areas on the foot of mount Hymettus. However,
higher particulate matter values were observed in the two offices which may be
associated not only to smoking events but also to poor cleaning of the areas and
resuspension because of human activity.
