Geochemistry of Respirable Particles in Barcelona ’ s Subway : How Reducing Commuting Exposure ? /

Concerning indoor air quality into the subway systems two aspects are considered. The first is the air quality on the platform of the stations and the second the air quality inside the train units. In both cases, suspended atmospheric Particulate Matter (PM) is the main critical parameter (Nieuwenhuijsen et al., 2007). This arises mostly from the abrasion products of rail track, wheels, and brake pads, as well as from sparkling in the catenaries.
