Physicochemical Characterization of Airborne Particulate Matter at a Mainline Underground Railway Station

Underground railway stations are known to have elevated particulate matter (PM) loads compared to ambient air. As these particles are derived from metal-rich sources and transition metals may pose a risk to health by virtue of their ability to catalyze generation of reactive oxygen species (ROS), their potential enrichment in underground environments is a source of concern. Compared to coarse (...

Temporal variability of the bioaerosol background at a subway station: concentration level, size distribution, and diversity of airborne bacteria.

Naturally occurring bioaerosol environments may present a challenge to biological detection-identification-monitoring (BIODIM) systems aiming at rapid and reliable warning of bioterrorism incidents. One way to improve the operational performance of BIODIM systems is to increase our understanding of relevant bioaerosol backgrounds. Subway stations are enclosed public environments which may be re...

Exposure level and distribution characteristics of airborne bacteria and fungi in Seoul metropolitan subway stations.

The exposure level and distribution characteristics of airborne bacteria and fungi were assessed in the workers' activity areas (station office, bedroom, ticket office and driver's seat) and passengers' activity areas (station precinct, inside the passenger carriage, and platform) of the Seoul metropolitan subway. Among investigated areas, the levels of airborne bacteria and fungi in the worker...

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...

Target-hardening at a New York City Subway Station: Decreased Fare Evasion — at What Price?

This paper evaluates the effect of the installation of "high-wheel" turnstiles on the incidence of fare evasion at a subway station in New York City. Ridership, summons and arrest data at the treatment station and two adjacent control stations suggest that the new high-wheel turnstiles were somewhat effective in reducing fare evasion, with little evidence of displacement. In light of these resu...
