^A) Tasks were performed without using the bathroom fan
^B) Each value is the average of two side-by side breathing zone samples collected and analyzed according integrated sampling method EPA TO-17
^C) The 10 minute average TVOC concentrations measured using a photo-ionization detector (PID)
^D) The highest TVOC concentrations recorded by the PID during 10 min tasks.
