Twenty-eight dwellings located in the Greater Copenhagen area in Denmark were investigated in this
study. Temperature, relative humidity and air exchange rate were measured. Dwelling characteristics
including floor area, volume of the living room, floor material, year of construction of buildings and floor
level were collected. The microbial exposure was measured by quantifying fungi, bacteria and endotoxin
concentration in airborne dust collected by Electrostatic Dust fall Collectors (EDCs). The Total Inflammatory
Potential (TIP) of the dust was also measured.
