在通勤时，人们暴露在高浓度的城市空气污染物中，可能对健康产生不利影响。本研究旨在评估通勤者在里斯本乘汽车、自行车、地铁和公共汽车旅行时对颗粒物（PM）的暴露。PM2.5和PM10的质量浓度在地铁内较高。另一方面，最高的BC和PN0.01-1的平均浓度分别在汽车和公共汽车模式。在汽车中，室外浓度和通风类型似乎影响室内浓度。事实上，通风的使用导致PM2.5和PM10浓度的降低和BC浓度的增加。最高吸入剂量主要在自行车旅行中观察到，这是由于旅行时间最长，加上体力活动增强，因此吸入率最高。(C)2019爱思唯尔有限公司版权所有。
While commuting, individuals are exposed to high concentrations of urban air pollutants that can lead to adverse health effects. This study aims to assess commuters' exposure to particulate matter (PM) when travelling by car, bicycle, metro and bus in Lisbon. Mass concentrations of PM2.5 and PM10 were higher in the metro. On the other hand, the highest BC and PN0.01-1 average concentrations were found in car and bus mode, respectively. In cars, the outdoor concentrations and the type of ventilation appeared to affect the indoor concentrations. In fact, the use of ventilation led to a decrease of PM2.5 and PM10 concentrations and to an increase of BC concentrations. The highest inhaled doses were mostly observed in bicycle journeys, due to the longest travel periods combined with enhanced physical activity and, consequently, highest inhalation rates.
