Finding F-0085

“Indicatively, indoor exposure in Res_2, with the open fireplace together and the presence of tobacco smokers, PM2.5 levels are considerably high (mean PM2.5 = 137.56 μg/m3).”

Xydi et al. Assessing the Impact of Spatial and Temporal Variability in Fine Particulate Matter Pollution on Respiratory Health Outcomes in Asthma and COPD Patients (2024). Journal of personalized medicine. Page 7. CKB 5958

Structure

Source: Tobacco smoke (secondhand smoke)
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: five patients with asthma or chronic obstructive pulmonary disease (average age 50 years, 40 % male)
Setting: home, GR (one year)
Study design: panel study: five patients with asthma or COPD monitored over a whole year with 24 h indoor and outdoor PM2.5 measurements, daily peak expiratory flow and biweekly symptom reports (linear mixed effect models, generalized estimating equations) (class 3)
Effect: mean 137.56
Averaging time: 24 h monitoring over a year
Sample: 5 participants
Caveat: one residence (Res_2) with an open fireplace and tobacco smokers
