摘要：The health and comfort of building users is animportant aspect in determining their quality of life.An increase in particulate matter (PM) aircontamination and its negative impact on humanhealth have resulted in efforts to monitor and identifyits sources. The occurrence of indoor PM depends onoutdoor pollution and its transportation indoors aswell as the presence of indoor pollution sources.Indoor sources include building materials;furnishing, heating, ventilation and air conditioningsystems; activities related to combustion processes;and occupancy activities. This paper aims to carryout an experimental investigation of PM in theindoor air of selected offices. The mass and numberconcentrations of PM for fractions of 0.5, 1.0, 2.5,5.0 and 10.0 μm were monitored and evaluated todetermine the extent of exposure of employees inoffice buildings in Slovakia. The monitoring of eightoffices showed that mass concentrations of PM10exceeded the maximum allowed value in 37.5% ofthe monitored offices. PM mass concentrationsranged widely based on particle size: 28.0-113.4,19.0-59.5, 4.6-17.0, 1.9-11.4 and 1.1-7.0 ȝJ P-3 forPM10, PM5, PM2.5, PM1 and PM0.5, respectively.Measurement results for two offices when they wereoccupied and unoccupied showed higher particlemass concentrations in unoccupied offices than inoccupied offices for all size fractions. Measurementsof number concentrations of 0.3-1.0 μm fractionswere higher in offices without activity thanconcentrations in offices with activity.
