This study examines the levels of suspended particles (PM10 and PM2.5) in residential settings in Bor, Serbia, alongside simultaneous outdoor measurements of PM. The project lasts 2 years and involves 30 apartments per year, selected based on criteria such as window type, connection to central heating, non-smoking status, distance from major pollution sources, and prevailing wind direction. Results from the winter measurement campaign (heating season) in 15 apartments, presented here, show that indoor PM concentrations vary significantly depending on ventilation habits, window type, and proximity to pollution sources. Measurements were conducted over 45 days during the heating season, and residents maintained activity diaries to document household activities. The average PM10 concentration in apartments was 18.2 µg/m³, while the average PM2.5 concentration was 12.0 µg/m³. The average indoor/outdoor concentration ratio was 0.58 for PM10 and 0.68 for PM2.5. The final results of this project will support the development of recommendations aimed at reducing indoor air pollution in urban homes across Serbia.
