Abstract
To effectively reduce PM10 generated in concourses and platforms of subway stations, a research is being conducted to find the PM10 source. The main source of PM10 in subway stations was PM10 generated in the main line tunnels, which was generated in proportion to the frequency of the train operation. Each amount of the PM10 generated when the train was operated once, was constant regardless of the time. On the assumption that the PM10 level in a tunnel of a line is a sum of newly generated amount of dust when the subway passes and the amount carried from the adjacent stations by the wind generated from the subway rolling stocks, the method which estimates the intensive PM10 occurring section was developed and applied to the 12 stations between Cheongdam and Jangseungbaegi in Seoul Subway Line 7.
