这项研究检查了通勤者接触六种与汽油相关的挥发性有机化合物（VOC）的情况：苯、甲苯、乙苯、间/对二甲苯、邻二甲苯和甲醛。比较了马萨诸塞州波士顿市四种不同通勤方式（驾车、地铁、步行和骑自行车）下通勤者暴露的VOC浓度。此外，亦测量了参与者家中及办公室的挥发性有机化合物浓度。此外，亦评估了不同交通模式、汽车型号及车辆通风条件等因素对车内挥发性有机化合物浓度的影响。驾驶私家车与较高的VOC浓度有关，在城市道路上通勤导致VOC浓度最高。使用汽车加热器导致车内VOC浓度较高。地铁通勤者在地下停留的时间越长，他们的VOC暴露量就越高。从家到工作的汽车或地铁通勤约占这些化合物暴露总量的10%至20%。
This study examines the commuter's exposure to six gasoline-related volatile organic compounds (VOCs): benzene, toluene, ethylbenzene, m-/p-xylene, o-xylene, and formaldehyde. The VOC concentrations to which commuters were exposed in four different commuting modes (driving, subway, walking, and biking) in Boston, Massachusetts, are compared. The VOC concentrations in participants' homes and offices were also measured. Factors that could influence in-vehicle VOC concentrations, such as different traffic patterns, car model and vehicle ventilation conditions, were also evaluated. Driving a private car was associated with higher VOC concentrations and commuting on urban roadways resulted in the highest VOC concentrations. The use of car heaters resulted in higher in-vehicle VOC concentrations. The longer the subway commuters stayed underground, the higher their VOC exposures. The home-to-work car or subway commute represented about 10 to 20 percent of an individuals total VOC exposure for these compounds.
