  1. Statistically significant constituent values from baseline (p < 0.05) are in bold. Statistically significant differences (p < 0.05) found in baseline concentrations (N = 4) between ventilation conditions are denoted with an asterisk.
  2. BBV Below baseline value, LOQ Limit of Quantification is based upon the amount of air sampled and is a composite average from all 4 air samplers used in the six runs.
