Measured Levels of Indoor Particulate Matter in Study Homes (repeated measures, n=71)
| BC (μg/m3) | UVPM (μg/m3) | PM2.5 (μg/m3) | Fungi (SE/m3) | |
|---|---|---|---|---|
| Minimum | < LOD | < LOD | <LOD | 1 |
| Q1 | 0.2 | 0.8 | 5.3 | 84 |
| Median | 0.5 | 1.6 | 8.7 | 198 |
| Mean | 0.6 | 5.8 | 14.6 | 420 |
| Q3 | 0.8 | 4.8 | 14.5 | 599 |
| Maximum | 3.0 | 60.2 | 81.4 | 2346 |
| SD | 0.5 | 11.3 | 17.7 | 502 |
BC = black carbon, UVPM = ultraviolet absorbing particulate matter (light absorbing PM2.5 emitted from smoldering organics such as smoking cigarettes and burning fireplace wood), Fungi = fungal spore equivalents per cubic meter (SE/m3), Q1 = 25th percentile, Q3 = 75th percentile, LOD for BC = 0.12 μg/m3, LOD for UVPM = 0.18 μg/m3, LOD for PM2.5 = 0.3 μg/m3.
