VEHICLE OCCUPANTS' EXPOSURE TO AROMATIC VOLATILE ORGANIC COMPOUNDS WHILE COMMUTING ON AN URBAN-SUBURBAN ROUTE IN KOREA

In this study. levels of exposure to six selected aromatic volatile organic compounds (VOC) inside cars and buses are identified for commuting journeys on an urban-suburban route in Korea. A bus-service route was selected to include three segments of Taegu and one suburban segment (Hayang) to satisfy the criteria specified for this study. This study indicates that motor vehicle exhaust and evaporative emissions are major sources of both car and bus occupants' exposures to aromatic VOCs in both Taegu and Hayang. A nonparametric statistical test (Wilcoxon test) showed that inside cars benzene levels were significantly different from those in buses for both urban-segment and suburban-segment commutes. The test also showed that the benzene-level difference between urban-segment and suburban-segment commutes was significant for both cars and buses. An F-test showed the same statistical results comparing the total concentration of the six target VOCs (benzene, toluene, ethylbenzene, and o,m,p-xylenes) inside cars as those for comparison of the benzene concentration. There was no significant difference among the three urban-segment commutes between the morning and evening commutes.
