Abstract

This study was performed to investigate the concentration levels of CO2 and the associated parametersin the subway from lines 1 to 8 in Seoul metropolitan area, during 1 to 30 Sept. 2005. CO2 concentrationwas measured at the entrance and center in subway passenger cabin by non-dispersive infrared analyser.The associated parameters for CO2 were estimated based on the number of passenger, open and closeddoors etc.The mean CO2 concentrations were measured to be 1,646±712 ppm in subway passenger cabins. The CO2concentrations showed the highest values between 7 and 9 AM in rush hour(p〈0.01). The correlationcoefficient between CO2 and the number of passenger was highly significant(r=0.824). The general linearmodel indicated that subway line, subway location (ground and underground tract), and measurement point(enterance and center of cabins) and running time (morning and afternoon) significantly influenced theconcentrations of CO2. An extended study is needed to examine the sources of CO2 in subway cabins andto compare pollutants concentration among subway lines.
