Living-room air pollution linked with self-reported symptoms in Ethiopian households

Researchers used systematic random sampling to assess indoor air quality and household characteristics in 265 households in Jimma Town, Ethiopia. Measurements of total volatile organic compounds (TVOC) and particulate matter (PM2.5–10) were taken in living rooms during non-cooking periods. The study also recorded ventilation, room size, household product use and self-reported health problems.

TVOC concentrations were 501–750 µg/m³ in 36.2% of households; PM concentrations most commonly fell in the 0.051–0.1 mg/m³ range (30.2%). Nearly 60% of households had living rooms smaller than 60 m³, and 39.6% lacked proper ventilation. Respondents reported using cleaning products (81.5%), personal care products such as perfumes (72.8%) and insecticides (53.6%); 37% said they lacked a kitchen. Respiratory or eye-related problems were reported by 46.4% of households.

The findings draw attention to living rooms as a possible exposure setting beyond kitchens. However, the cross-sectional design, short-term spot measurements and self-reported symptoms mean the results show associations, not causation. The authors call for further research on locally appropriate interventions.
