초록

This paper was conducted concerning the degree of indoor air quality in public transport vehicles such as taxicabs, buses and subway trains, as sampled through the active participation of drivers and passengers in Seoul between 13th August 2005 and 2nd November 2005. The results were summarized as follows: 1. Among the measured substances especially respirable particulate matters ($PM_{10}$), total bacteria counts (TBC) and carbon dioxide ($CO_2$) exceeded the standard level of $150{\mu}g/m^3,\;800CFU/m^3$ and 1000ppm. 2. The concentration of carbon dioxide ($CO_2$) in taxi recorded 2491ppm, which is more than the standard amount of 1000ppm. This level was comparatively higher than all other public transportation methods. Total bacteria counts (TBC) in bus and subway recorded $1082CFU/m^3\;and\;1856CFU/m^3$, respectively. 3. The drivers who regularly work long hours showed the higher concern about contamination of the air inside the public transport vehicles and they considered it to be worse than the air outside. In contrast, the general public showed less concern about the air quality inside the public transport vehicles. However, they too acknowledged that the quality of the air inside the public transport vehicles was poor. In regards to the degree of indoor air quality in the public transport vehicles, a counterplan must be implemented urgently to effectively combat the excessive levels of $PM_{10}$, microorganism and $CO_2$. We need to gather more conclusive evidence pertaining to other possible contaminants and influencing factors.
