As the National Health Promotion Act was again revised, expanding the coverage of non- smoking areas to include restaurants and Internet Cafe, as well as entertainment venues such as bars and pubs, the purpose of this study was to determine the change in PM2.5 concentrations before and after non-smoking policy was enforced and to evaluate the status of the non-smoking policy on its own. PM2.5 Concentration levels were measured on Internet Cafes (n=12) in Hayangsi using fine-particle direct monitor, from December in 2013 through February in 2014. For accurate measurement of the concentration of PM25, researchers investigated the environmental impacts of each factor in Internet Cafe (block form between Internet Cafe and smoking room, the number of cigarettes and users observed). Measured PM2.5 concentration data were processed and analyzed. When non-smoking policy is not enforced the average indoor and outdoor PM2.5 concentrations were found to be 90.89±64.92 μg/m3 and 26.69±14.51 μg/m3 respectively, otherwise when non-smoking policy is enforced, the average indoor and outdoor PM2.5 concentrations were 77.90±53.67 μg/m3 and 44.77±23.77 μg/m3. Though we found that concentrations were numerically lower than before, the concentration of post results showed no significant difference compared to the previous results.
