Abstract

This study was performed to investigate airborne volatile organic compounds(VOCs), formaldehyde,respiratory particulate for concentration in primary schools. The concentrations of major indoor airpollutants(VOCs ; benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde, PM-10) were observedfrom November to December 2006. Sampling was undertaken at 81 primary schools. The sampling sites ofair pollutants are classroom and hallway. VOCs with distribution of most of general environmentalcontamination material will be able to confirm that it shows the log-normal distribution which is similarexposure 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 villagearea. It tried to observe the I/O ratio, it appeared highly from the interior of the material of most. The meanconcentrations of formaldehyde, respiratory particulate were 22.07㎍/㎥, 88.06㎍/㎥ respectively. Indoor andoutdoor ratios(I/O) of formaldehyde and respiratory particulate were 3.6 and 1.4, respectively. Theconcentration of respiratory particulate is 27.2% higher than guideline for school hygiene(100㎍/㎥). Fromthe comparison in the construction year, the highest concentration of formaldehyde is showed under oneyear. However, as time passed by the concentrations of formaldehyde become lower.
