This study was performed in the 48 selected public facilities in three metropolitan cities (Seoul, Daejeon, and Kwangjoo) and three general cities (Suncheon, Gwangyang, and Yeosu) to measure of the characteristics from May to October 2011. Air samples (PM2.5) were collected at the indoor and outdoor places for 24-hrs using the mini volume air sampler and analyzed 24 gaseous and particulate polycyclic aromatic hydrocarbons (PAHs) through the GC/MS. The recoveries of gaseous and particulate PAHs ranged between 60.7% to 127.2% and 57.7% to 132.5% respectively and its relative standard deviation (RSD) was 11.1%. This QA/QC results about the were adequate for the Korean national standards. The concentration levels of the PAHs in present study were acenaphthene 〉dibenz(a,h)anthracene 〉benzo(g,h,i)perylene 〉3-methylcholanthrene 〉 indeno[1,2,3-cd]pyrene for the particulate PAHs in the 48 selected public facilities. In the case of acenaphthene, the mean concentration showed the highest levels of 22.42 ng/㎥ and 34.57 ng/㎥ in the level of gaseous and particulate phase, respectively. The total PAHs concentration for the PC room is the highest in surveyed public facilities of this study and the smoking/non smoking ratio in the PC room was 3.45. This results indicated that smoking in the PC room is seemed to play a major source and the effective risk management strategies were needed to minimize or eliminate the public health effect for customers in the PC room.
