Figure 3.

PM concentration and mass inhaled by a pedestrian for a typical acceleration test. Once the data was acquired following a typical drive-by acceleration test, particle size-mass correlations and human breathing rates were applied to the data. The red line in the figure represents the PM concentration measured at the mannequin's mouth. The light blue line corresponds to the mass inhaled using the breathing rate of an adult walking. The dark blue line represents the mass inhaled using a breathing rate of an adult standing still.
