Abstract: This study investigated bus commuter exposure to PM₁₀, NO_X, CO and O₃, measured alongside traffic corridors at bus stops in Guangzhou, China. The average commuter exposure was 158.4 µg m⁻³, 192.0 ppb, 2.0 ppm, and 7.7 ppb for PM₁₀, NO_X, CO, and O₃, respectively. The pollutant concentrations (with the exception of O₃) were significantly higher at bus stops compared to those at the city's fixed monitoring station (FMS) that is located away from the bus stop. Combined with other studies, the exposure of bus passengers to PM₁₀, NO_X and CO was observed to be higher than it was when they were near the roadside or at the bus stop. The average bus commuter spent 36.4% and 56.1% of the travel time riding the bus and walking along the roadside, implying that the bus commutation and the roadside were two major exposure scenarios encountered during their daily journey.
