Table 2.
Average airborne SARS-CoV-2 concentrations (Cexp) and expanded uncertainty (UC-exp) resulting from the experimental analysis for both the scenarios considered. Cycle threshold (CT) and CTM values for the endogenous gene RP (adopted for internal control) and for the gene ORF8 (adopted to calculate the concentration through the quantification curve) are also reported.
| Experiment/scenario | Respiratory activity | CT for endogenous gene target (RP) | CT for virus gene target (ORF8) | CTM (RNA copies mL-1) | Cexp (RNA copies m-3) | UC-exp (RNA copies m-3) |
|---|---|---|---|---|---|---|
| A | Breathing | 38.42 | Undetermined | Undetermined | Undetermined | Undetermined |
| B | Speaking | 38.59 | 37.16 | 34.06 | 16.1 | 32.8 |
