Environmental health in subway stations, a typical type of urban underground space, is
becoming increasingly important. Ventilation is the principal measure for optimizing the …

Due to the rapidly increasing ridership and the relatively enclosed underground space, the
indoor air quality (IAQ) in underground subway stations (USSs) has attracted more public …

This research paper presents a comprehensive review of different types of air pollutants,
their concentration levels, sources contributing to air pollution, health impacts of pollutants …

The air quality in the subway metro indoor microenvironment has been of particular public
concern. With specific reference to the growing demand of green transportation and …

We present the first report of exposure to particulate matter by commuters at 12 underground
subway stations in Philadelphia, Pennsylvania, USA. Particle measurements were taken …

The effects of air pollution within subway systems on public health has far been overlooked.
A few previous studies have warned that particulate matter (PM)-bound metals in subway air …

Environmental particle exposure, often estimated as the particulate mass of particles with a
diameter< 10 μm,< 2.5 μm or< 1 μm (PM10, PM2. 5 or PM1), is known to have a negative …

Indoor air quality (IAQ) ventilation systems are widely used to control air pollutants in
subway platforms. When outdoor air is heavily contaminated by particulate matters (PMs), it …

As part of the European-funded IMPROVE LIFE project work programme experiments were
performed in the Barcelona Metro system with the objective of better understanding the …

In this study, variations of particulate matter (PM) concentrations in subway trains following
installation of platform screen doors (PSDs) in the Seoul subway system were investigated …
