The indoor air quality in public facilities has been well maintained as consciousness of facility owners is improved.However, the risk of PM2.5 and heavy metals in particulate matters have not been highlighted until now. So weinvestigated the particulate matters on major public transportation facilities such as subway, port and bus terminals.And we tried to figure out the characteristics of each facility groups by comparing the mass and metal concentrationbetween PM2.5 and PM10. As a results, the correlation between concentration of indoor particulate matters andthat of outdoor particulate matters shows higher strength in the case of bus terminals and port platforms thansubway platforms. However the total concentration of particulate matters and heavy metals were much higher insubway platforms than that of terminals and port platforms.
