Abstract

With on-site measurements, this paper analyzed the current status of airborne fungi in the child's bedroom of the residences in Shanghai and its associations with the characteristics of residences. The average concentration of airborne fungi in the 446 children's bedrooms was 310 CFU/m3 (range: 6 to 3184 CFU/m3). Only one bedroom had higher concentration of airborne fungi than the standard concentration of 2500 CFU/m3 with 3180 CFU/m3. Compared to the residences with building areas ≤ 75 m2, those residences > 100 m2 had significant higher average concentrations (mean ± standard deviation: 270 ± 183 vs. 354 ± 409). The children's bedrooms at the ground floor or the attic floor of the residential building had higher average concentration of airborne fungi than others. The results indicate that building characteristics of residences may be associated with the concentrations of airborne fungi in the child's bedroom.
