Abstract
This research aims to discern the characteristics of PM<sub>10</sub> concentrations measured in subway cabins, tunnels and outdoors at the Seoul Metropolitan subways. PM<sub>10</sub> concentrations in cabins were found between the range of 45.3 and 101.9μg/m<sup>3</sup>, and in tunnels the ranges were between 155.3 and 230.6μg/m<sup>3</sup>. PM<sub>10</sub> concentrations in cabins and tunnels during rush hours were 16.5% and 3.8% respectively higher than non-rush hours. Fine particles were higher than that of coarse particles both in subway cabins and tunnels.
Highlights
From the time its first line began operations in 1974, the Seoul Metropolitan Subway has been expanding to connect the entire city area
PM10 is a major pollutant in subway stations that is known to be generated from various factors such as subway train operation, passenger movement, and the inflow of outside air through the ventilation system
As PM10 concentrations measured in subways are generally higher and more toxic than those in the air (Nieuwenhuijsen et al, 2007), they play a major role in deteriorating subway air quality and as such require proper control
Summary
From the time its first line began operations in 1974, the Seoul Metropolitan Subway has been expanding to connect the entire city area. As additional subway lines are planned for other metropolitan cities, the number of passengers using subways nationwide is expected to grow significantly (Seoul, 2009). Air quality in subway cabins is comparatively worse than in the indoor spaces of other public buildings at ground level. PM10 is a major pollutant in subway stations that is known to be generated from various factors such as subway train operation, passenger movement, and the inflow of outside air through the ventilation system. As PM10 concentrations measured in subways are generally higher and more toxic than those in the air (Nieuwenhuijsen et al, 2007), they play a major role in deteriorating subway air quality and as such require proper control
