Our study was aimed at assessing the effects of indoor and outdoor emission sources on indoor and outdoor concentrations of ambient particulate matter (PM) and PM-bound polycyclic aromatic hydrocarbons (PAHs) in a small sawmill in Silesia, Poland. The concentrations of total suspended particles (TSP), of their respirable fraction (PM₄), and of 16 PM₄- and TSP-bound PAHs were measured. The indoor PM emission sources (i.e. the saw and other tools for wood processing) did not cause a significant hazard to the sawmill workers. Nonetheless, the concentrations of the 16 PAH mixtures within the sawmill were high, especially indoors. Such high indoor PM-bound PAH concentrations were due to sawdust-adsorbing PAHs coming from industrial PAH sources beyond the sawmill (a cokery).
