영문 초록

personal nitrogen dioxide(NO ) exposures for 31 professional drivers were measured using passive sampler and time activity diary in Asan and Chunan area, and were estimated using time-weighted average model. Mean concentrations of driver’s indoor and outdoor were 24.7±10.7 ppb and 23.3±8.3 ppb, respectively with indoor/outdoor of 1.1. Mean personal NO2 exposure was 30.3±9.7 ppb. Personal NO2 exposures were strongly correlated with indoor car NO2 levels (R2=0.80) rather than residential indoor NO2 level (R2=0.55). and outdoor NO2 level (R2=0.50). The driver’s NO2 exposure using LP-gas with 24.4±8.0 ppb were statistically different from those using diesel with 36.3 ±14.1 ppb(p<0.01). The effect of driver’s smoking for personal NO2 exposure was not found. It was considered that the main NO2 in driver is transportation. Since drivers mostly spent their times in indoor and inside car, time-weighted average model could be used to estimated personal NO2 exposure using time activity diary, Though we did not measure all microenvironments, the estimated personal NO2 exposures with 26.9±10.2 ppb were statistically correlated with measured personal NO2 exposures30.3±9.7 ppb (R2=0.89). The mean and standard deviation of personal NO2 exposure using Mote-Carlo simulation were 26.6 ±7.2 ppb.
