 Abstract
Objectives: High concentrations of airborne particulate matters (PM) can affect the health of passengers using public transportation. The objectives of this research were to develop a PM control system for a railway cabin and to evaluate the performance of the device under conditions of an actual journey. Methods: This study measured the concentrations of and simultaneously in a reference cabin and a cabin with the PM control device. Results: The average concentration in the reference cabin was 100 , and the concentration in the cabin with the control device was 79 . While the overall control efficiency of the control device was 15.4%, reduction was more effective for peak concentration. However, levels did not differ greatly between the reference cabin and the cabin with the control device. The ratio of to was 0.37. concentrations in cabins were not associated with ambient concentrations, indicating that the main sources of were present in cabins. Additionally, average concentration in the cabins was 1,359 ppm, less than the maximum of 2,000 ppm set out by the Korean Ministry of Environment`s guideline. The concentration in cabins was significantly associated with the number of passengers: the in-cabin concentration
