Fig. 6.

(Color Online) Predicted concentrations normalized to B1 at 4920 s for some patrons at tables A, B, and C, and other tables after table A patrons arrived at time zero (12:01 p.m.). Table A patrons left the restaurant at time 4920 s (1:22 p.m.). Due to the nature of the air flows, the concentrations for some patrons continued to rise after 4920 s. The results are used to calculate the exposure using the exposure duration data in Table 3. The prediction concentration profiles clearly show a separated ABC zone (i.e., bubble, including T04, which had no patrons), a T17/T18 zone, a zone with T11 and T13–16, and a zone with T07–T10 and T12 close to the outdoor air supply.
