Finding F-0904

“Median PM2.5 exposure during these activity periods was 97.9 μg/m3 (IQR: 22.9–482.0), whereas median PM2.5 background exposure concentrations (at times of no identified combustion sources) were 7.6 μg/m3 (IQR: 2.5–20.6).”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: adults in a rural village
Setting: personal exposure of the participant in the household, MW
Study design: observational study in a rural village of Malawi: twenty adults wore paired personal PM2.5 and carbon-monoxide monitors for 831 hours in total, with a structured activity diary, and exposures were split into activity peaks and background periods and modelled against fuel, stove and place of cooking (class 4)
Effect: median 7.6
Sample: 20 participants
