However, air quality in urban railway environments is worse than ambient air quality due tothe internal location of the source of air pollutants and the isolated space. In this paper, characteristics of particulatematter (PM) pollution in urban railway environments are described from the perspective of diurnal variation,chemical composition and source apportionment of PM. PM concentrations in concourse, platform, passengercabin, and tunnel are summarized through an analysis of 34 journal articles published in Korea and overseas. Thisinformation will be helpful in developing effective policies to reduce PM pollution in urban railway environments.
