High-level black carbon (BC) pollution is associated with traffic emissions in metropolitan areas with high vehicle density. Mobile monitoring was conducted to assess the in-vehicle BC exposure on three backbone ring roads (inner, middle, and outer ring roads) on October 14 and October 18, 2015 in Shanghai. Ambient BC monitoring was also simultaneously conducted in three fixed roadside stations from October 14 to October 20, 2015. Results of the mobile monitoring showed median BC personal exposure concentrations ranging from 5.0 μg m on the inner ring road to 13.5 μg m on the outer ring road. The ambient BC concentrations during the entire observation period showed an arithmetic mean and a standard deviation of 3.5 ± 2.9 μg m. The correlation analysis of urban roadside monitoring (Caoxi Road and South Zhongshan Road) and personal data showed a high and significant correlation. The results of this study highlight the critical level of BC pollution in Shanghai and facilitate the development of evidence-based public health interventions and control strategies to prevent the adverse health effects of BC pollution.
在车辆密度高的大都市地区，高浓度黑碳（BC）污染与交通排放有关。2015年10月14日和18日，在上海的三条主干环路（内环、中环和外环道路）上进行了移动监测，以评估车内BC暴露情况。2015年10月14日至20日，还在三个固定路边站点同时进行了环境BC监测。移动监测结果显示，BC个人暴露浓度中位数在内环路为5.0微克/立方米，在外环路为13.5微克/立方米。整个观测期内的环境BC浓度算术平均值和标准差为3.5±2.9微克/立方米。城市路边监测（漕溪路和中山南路）与个人数据的相关性分析显示出高度显著的相关性。本研究结果突出了上海BC污染的严重程度，并有助于制定基于证据的公共卫生干预措施和控制策略，以预防BC污染对健康的不利影响。
