Air quality in passenger cars of the ground railway transit system in Beijing, China☆

Granulometric and magnetic properties of deposited particles in the Beijing subway and the implications for air quality management

“…Frictional abrasion contributes 40-73% of PM10s at the platforms in the Milan subway system in Italy (Colombi et al, 2013). The secondary source is the particles carried by regular passengers and air flow from the outside urban environment (Kang et al, 2008;Li et al, 2006). Earlier toxicological research has pointed out that subway PMs induce oxidative stress in cultured human lung cell (Karlsson et al, 2005(Karlsson et al, , 2008 and impose strong self-limiting biological reactions on rodents (Bachoual et al, 2007), suggesting that the same PM might trigger health hazards in passengers.…”

“…Studies have been made to monitor the in-train PM2.5 levels in the Beijing subway system (Li et al, 2006(Li et al, , 2007. However, observations of PM concentrations alone may not be sensitive enough to characterize the intrinsic nature of the iron-containing particles.…”

“…While some studies (e.g. Li et al, 2006) have monitored the in-train levels of PM2.5s (particles < 2.5 μm), there is a lack of systematic assessment of the concentration and characteristics of iron-containing particles in the Beijing subway system. Here we report results of a study on the granulometric and magnetic properties of particulate samples collected at different localities of the Beijing subway system.…”
