A Darío Torrenti I Todo el viaje fue un error. Para ir a encontrarte necesitaba ropa gruesa, lo más abrigada posible. Pero si decidía no ir nada de eso era necesario. Le voy a decir que me caí, que me quebré una pierna y que no puedo ir, pensé. Le voy a decir que me desmayé y que desperté en un hospital y que no puedo ir, pensé. Comíamos lentejas, queso, olivas. Concentrado y sin hablar sacabas pequeñas piedras negras que ponías aparte y con las que yo jugaba a formar figuras sobre el mantel. Al principio era como un juego, como ir caminando solos, pero no. Traté de concentrarme en esos detalles, en mis pies cada vez más fríos y húmedos.

Commuters' Exposure to Particulate Matter Air Pollution Is Affected by Mode of Transport, Fuel Type, and Route
Background: Commuters are exposed to high concentrations of air pollutants, but little quantitative information is currently available on differences in exposure between different modes of transport, routes, and fuel types. Objectives: The aim of our study was to assess differences in commuters' exposure to traffic-related air pollution related to transport mode, route, and fuel type. Methods: We measured particle number counts (PNCs) and concentrations of PM₂.₅ (particulate matter ≤ 2.5 um in aerodynamic diameter), PM₁₀, and soot between June 2007 and June 2008 on 47 weekdays, from 0800 to 1000 hours, in diesel and electric buses, gasoline-and diesel-fueled cars, and along two bicycle routes with different traffic intensities in Arnhem, the Netherlands. In addition, each-day measurements were taken at an urban background location. Results: We found that median PNC exposures were highest in diesel buses (38,500 particles/cm³) and for cyclists along the high-traffic intensity route (46,600 particles/cm 3 ) and lowest in electric buses (29,200 particles/cm³). Median PM₁₀ exposure was highest from diesel buses (47 μg/m³) and lowest along the high-and low-traffic bicycle routes (39 and 37 μg/m³). The median soot exposure was highest in gasoline-fueled cars (9.0 х 10⁻⁵/m), diesel cars (7.9 х 10⁻⁵/m), and diesel buses (7.4 х 10⁻⁵/m) and lowest along the low-traffic bicycle route (4.9 х 10⁻⁵/m). Because the minute ventilation (volume of air per minute) of cyclists, which we estimated from measured heart rates, was twice the minute ventilation of car and bus passengers, we calculated that the inhaled air pollution doses were highest for cyclists. With the exception of PM₁₀, we found that inhaled air pollution doses were lowest for electric bus passengers. Conclusions: Commuters' rush hour exposures were significantly influenced by mode of transport, route, and fuel type.
