“However, during the wildfire season, the average outdoor PM2.5 concentration (187 μg/m3) was moderately higher than the indoor concentration (162 μg/m3), indicating that indoor environments provided some protection at this time.”

Structure

Source: Wildfire smoke
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: pregnant women
Setting: home
Study design: study of wildfire smoke infiltration and the exposure of pregnant women: indoor, outdoor and personal fine particulate matter measured with a sensor network and personal samplers in the wildfire season and in the non-wildfire season (class 4)
Effect: mean 162
Caveat: the study reads the difference as some protection indoors, but calls the indoor level still hazardous
