Abstract:PM1 exposure by typical transport modes (bus and subway) in Shanghai were measured from Nov. 14th to Nov. 26th , 2011 using DustTrakTM-II-8530 to understand the fine particulate matter exposure characteristics by these transport modes. The average PM1 exposure concentrations were (0.079±0.067) mg/m3 and (0.065±0.056) mg/m3 for bus and subway trips respectively. The in-transit exposure concentrations, especially in-train, were lower than the outdoor exposure concentration. The inhalation doses were (0.028±0.024) mg and (0.034±0.033) mg for bus and subway trips respectively. The in-transit exposure dose contributed 52.2% to the total inhalation dose along bus trips. The inhalation doses on subway trips mainly occurred in the outdoor and in-station sections (42.4% and 44.2% respectively). The difference between the inter-mode relationship of the exposure concentrations and that of the inhalation doses indicated that travel pattern and inhalation rate as well as exposure concentration were key factors for the evaluation of the public health impact of air pollution.
