This study was performed to investigate airborne volatile organic compounds(VOCs), formaldehyde, respiratory particulate for concentration in primary schools. The concentrations of major indoor air pollutants(VOCs , benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde, PM-10) were observed from November to December 2006. Sampling was undertaken at 81 primary schools. The sampling sites of air pollutants are classroom and hallway. VOCs with distribution of most of general environmental contamination material will be able to confirm that it shows the log-normal distribution which is similar exposure distribution. The exposure quality of VOCs and the place pollution level was indoor> hallway>outdoor, which whole is located in the metropolis and the industrial areas is higher than farm village area. It tried to observe the I/O ratio, it appeared highly from the interior of the material of most. The mean concentrations of formaldehyde, respiratory particulate were 22.07㎍/㎥, 88.06㎍/㎥ respectively. Indoor and outdoor ratios(I/O) of formaldehyde and respiratory particulate were 3.6 and 1.4, respectively. The concentration of respiratory particulate is 27.2% higher than guideline for school hygiene(100㎍/㎥). From the comparison in the construction year, the highest concentration of formaldehyde is showed under one year. However, as time passed by the concentrations of formaldehyde become lower.
