Finding F-0084

“Identified indoor PM2.5 sources included tobacco use, open fireplaces, and cooking, resulting in average indoor PM2.5 concentrations of 63.89 μg/m3 (±68.41), significantly exceeding revised World Health Organization (WHO) guidelines.”

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 63.89
Averaging time: 24 h monitoring over a year
Sample: 5 participants
Caveat: printed as ± 68.41 without naming the measure of spread; the identified indoor sources were tobacco use, open fireplaces and cooking
