The paper investigates PM2.5 levels and composition in 3 different locations in Poland for cold and warm period of 2013. The highest share of SOC and POC in PM2.5 was found in heating season, which was probably due to an increase in the activity of local emission sources of PM, especially biomass burning and fossil fuel combustion in residential sector, while SIA contribution in PM2.5 mass was relatively constant during heating and non-heating period at all 3 sites. During non-heating season air mass back trajectories were grouped into 5 clusters representing mostly westerly flows (50–72 %). During heating season the trajectories were grouped into 6 clusters coming mostly from eastern directions (54–64 %).
