It is well-documented that subway stations exhibit high fine particulate matter (PM 2.5) concentrations. Little is known about the potential of river-tunnels to increase PM 2.5 concentrations in subways. We hypothesized a "river-tunnel" effect exists: Stations adjacent to poorly ventilated tunnels that travel beneath rivers exhibit higher PM 2.5 co...
