Fine Particulate Matter Exposure and Health Impacts from Indoor Activities
Figure 3
Bars represent PM2.5 concentrations for an average scenario with 0.6 ACH without indoor emission (base) and with emissions from activities (increment) for a room with small volume and high occupancy (HO) and a room with high volume and low occupancy (LO). Markers represent concentrations for (a) three other ACH in the small room: 0.2 ACH (always closed), 3 ACH, and 14 ACH (always open), and (b) two ACH: 3 ACH and 14 ACH for different opening scenarios (open before, open during, and open after).
