Finding F-0206

“OM accounted for 29%, 30% and 29% of PM2.5 mass outdoors and 48%, 55% and 61% of indoor PM2.5 mass in Los Angeles Co., Elizabeth and Houston study homes, respectively.”

Fine organic particulate matter dominates indoor-generated PM 2.5 in RIOPA homes (2006). Journal of exposure science & environmental epidemiology. Page 1. CKB 0282

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: home, US
Study design: RIOPA study: 48-hour indoor and outdoor PM2.5 organic and elemental carbon measured at 173 homes in Houston, Los Angeles County and Elizabeth (New Jersey), species mass balance and mass-balance modelling (class 4)
Effect: ratio 48
Averaging time: 48-hour samples
Sample: 173 homes
Caveat: organic matter is a component of PM2.5, filed under particulate-matter
