Finding F-0170
“Indoor PM2.5 concentrations in homes without kerosene heaters (17.43 ± 23.63 pg/m3) were about 40% higher than outdoor levels (12.56 ± 7.27 pg/m3) and homes with kerosene heaters had indoor PM2,5 concentrations almost 2.5 times the outdoor levels (29.97 ± 23.58 pg/m3).”
Structure
- Source

- measurement study: 24-hour indoor and outdoor samples of PM10, PM2.5, particle strong acidity, sulfate, nitrate, ammonia, nitrous acid and sulfur dioxide at 281 homes in southwest Virginia and Connecticut in winter and summer, 74 winter homes using kerosene heaters (class 4)
- Effect
- mean 29.97
- Averaging time
- 24-hour samples
- Flags
- unit-suspect
- Caveat
- the text layer prints pg/m3 where the paper means μg/m3; the spread is printed as ± and read as a standard deviation
