Structure

Factor
Particulate matter (PM₂.₅ and PM₁₀)
Setting
home (summer)
Study design
measurement campaign in residences: fine particles and black carbon sampled indoors and outdoors in summer and in winter, with models relating the indoor concentrations to the outdoor ones and to the occupants' behaviour (class 4)
Effect
mean 25.8
Caveat
the study says the outdoor concentrations accounted for only little to moderate variability indoors and that cigarette smoking explained a much greater proportion
