Traffic is a main source of air pollutants in urban areas and consequently daily peak exposures tend to occur during *** exposure to particulate matter(PM)was monitored while cycling and travelling by bus,car and metro along an assigned route in Lisbon(Portugal),focusing on PM_(2.5) and PM_(1)0(PM with aerodynamic diameterindoor-outdoor interplay was also *** PM_(2.5) mean concentrations were 28±5,31±9,34±9 and 38±21μg/m 3 for bus,bicycle,car and metro modes,*** carbon concentrations when travelling by car were 1.4 to 2.0 times higher than in the other transport modes due to the closer proximity to exhaust *** are marked differences in PM chemical composition depending on transport *** particular,Fe was the most abundant component of metro PM,derived from abrasion of rail-wheel-brake *** concentrations of Zn and Cu in cars and buses were related with brake and tyre wear particles,which can penetrate into the *** the motorised transport modes,Fe,Zn,Cu,Ni and K were correlated,evidencing their common traffic-related *** average,the highest inhaled dose of PM_(2.5) was observed while cycling(55μg),and the lowest in car travels(17μg).Cyclists inhaled higher doses of PM_(2.5) due to both higher inhalation rates and longer journey times,with a clear enrichment in mineral *** presented results evidence the importance of considering the transport mode in exposure assessment studies.
