Table 2.
Average particulate concentration (μg/m3) for submicron (PM1), less than 2.5μm (PM2.5), respirable, less than 10μm (PM10), and total fractions for all eighteen experiments as well as bedroom and common room fire experiments over a 60 minute data collection period. Data are presented as median (range).
