Table 2 Sample information for the two main experiments: Moisture Availability and Collection Location Samples.

Moisture Availability Samples

Samples incubated at 50%, 65%, 70%, 75%, 80%, 85% and 95% ERH for 4 weeks at 25°C. Chemical emissions were measured using the flow-through chamber approach in which emissions were measured for a total of 2 hours.

   Carpet

Carpet A sterilized (control)

Carpet A with CA dust

    Drywall

Painted Drywall A sterilized (control)

Painted Drywall A inoculated in CA home 1

Collection Location Samples

Duplicates of each sample type were incubated at 50% and 85% ERH for 4 weeks at ambient room temperature. Chemical emissions were measured using a direct sampling approach in which the sampling line for the volatile chemistry instrument was inserted into the parafilm covering the jar of an individual sample.
