Abstract
In order to evaluate the hazardous effects of environmental tobacco smoking (ETS), we measured the concentrations of major aromatic VOC from those who decided to participate in a program to quit smoking. By acquiring the air samples both before and after quitting smoking (QS), we were able to compare their BTEX concentration levels in their breathing air. The results of our study clearly showed that BTEX levels in respiring air samples were significantly high prior to the QS period. It was found that toluene maintained the highest concentration levels both before and after the QS period. However, the level of reduction was most significant in the case of benzene, as it was decreased 10 times from 4.8 to 0.46 ppb. When their reduced BTEX levels are compared to those who never smoked before, differences were not significant enough to distinguish in statistical terms. The overall results of this preliminary study suggest that BTEX levels in breathing air samples can be used as one of the most sensitive signals to judge the effect of QS.
