Abstract

Volatile Organic Compounds(VOCs) contribute to the formation of ozone and PAN which are injurious to health through complex photochemical reactions. Growing consumption of fossil fuels results in significant emission of VOCs and other air pollutants into the atmosphere. In this study, Ambient an grab samples of VOCs were collected at the platform and the concourse of six stations in the subway from February 21th to 28th. Among the total contents, Toluene (118.74 ppm) showed the highest concentration in the Indukwon station platform while other contents were measured low concentrations. Also, the platform concentrations were higher than the concourse concentrations through the whole contents.
