 1. Background There is controversy about the differences in air pollution exposure and inhalation dose between different modes of transportation. The aim of this study was to review air pollution exposure and inhaled dose according to mode of transport and pollutant, and their effects on years of life expectancy, YLE. 2. Methods This systematic review searched 10 online databases from Inception to April 13, 2016, for cohort, cross-sectional, and experimental studies that compared exposure to carbon monoxide, black carbon, nitrogen dioxide, and fine and coarse particles in active commuters, pedestrian or cyclist, and commuters using motorized transport, car, motorcycle, bus, or massive motorized transport, MMT. The study excluded studies that measured air pollution exposure exclusively with biomarkers or on the basis of simulated data.
