  • a The mean is the average of the median concentrations for all buildings, restricted to buildings where the fungus was detected.

  • b The median value is the average of the median concentrations for all buildings, restricted to buildings where the fungus was detected.

  • c The 95th percentile is based on the median concentrations for all buildings, restricted to buildings where the fungus was detected.

  • d Aspergillus species includes Eurotium, Emericella, A. flavus, A. fumigatus, A. niger, A. versicolor, and all other Aspergillus species listed in Table 3.

  • e Value for indoor samples/value for outdoor samples (standard deviation for indoor samples/standard deviation for outdoor samples).
