Finding F-1569

“A multivariate model indicated that outdoor particles penetrated indoors with an efficiency of 0.48 and were therefore responsible for only 25% of the mean indoor concentration.”

Structure

Factor
Particulate matter (PM₂.₅ and PM₁₀)
Setting
home
Study design
study of particle concentrations in inner-city homes: two-week average indoor and outdoor fine particles measured in homes across several cities, with a multivariate model separating the outdoor contribution from the indoor sources (class 4)
Effect
other 0.48
Caveat
an efficiency between 0 and 1 from the study's own multivariate model, not a measured concentration
