Particulate matters levels in subway tunnels and cabins

초록

This research aims to discern the characteristics of PM10 concentrations measured in subway cabins, tunnels and outdoors at the Seoul Metropolitan subways. PM10 concentrations in cabins were found between the range of 45.3 and 101.9μg/m3, and in tunnels the ranges were between 155.3 and 230.6μg/m3. PM10 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.
