Seasonal variation in health exposure to PM-bound Polycyclic Aromatic Hydrocarbons in selected sport facility

In this paper, for the one selected sport facility in Warsaw in heating and non-heating periods: 1) average concentration of 15 polycyclic aromatic hydrocarbons (PAHs) associated with respirable fraction of particulate matter (PM4); 2) health hazards from the PM4-bound PAHs; 3) PM4-bound PAHs origin are described. PM samples were collected for 10 days of June and 10 days of November simultaneously inside and outside of the sports hall and next were analysed in term of PAHs content. Obtained results allowed to calculate selected indicators of cumulative exposure to the PAH mixture and the specific diagnostic ratios for individuals compounds from the PAHs group which indicate origin of PAHs. It has been shown that the exposure of sports hall users to PM4-bound PAHs is significantly higher in heating than non-heating season. It also confirm that fossil fuels and biomass combustion in heating period in Warsaw have a strong influence on the level of health exposure to PAH mixture both outdoor and inside of the buildings
