Although a scooter is a convenient transportation means for a short distance traveling with a light package in the congested urban center, it might be one of the significant sources of air pollutants to which many people can easily be exposed during its passing-by. In this paper, we measured concentrations of gases and particles emitted from a scooter at roadside with no other traffic. To understand the characteristics of scooter emissions with respect to driving speed (idling, 30 ㎞/h) at the roadside, total particle number concentration, particle size distribution, average surface area of particles deposited in the alveolar region, and concentrations of black carbon, CO, and NO<SUB>x</SUB> were measured. The concentrations of the particle number, surface area of deposited particles, CO, and NO<SUB>x</SUB> were highly fluctuated in the scooter’s idling condition. The trends of particle number concentration, CO, and NO<SUB>x</SUB> generation were similar to one another. When the scooter started to move, all of NO<SUB>x</SUB>, CO and particle number concentrations increased and after it passed by at the speed of 30 ㎞/h, the concentration peaks of the particles and gases appeared at the same time. Unimodal size distribution with ~70 and ~93 ㎚ mode diameters was observed for the idling and cruising condition, respectively. From this work, we found that emission from a passing vehicle could be characterized using a roadside monitoring technique.
