Figure 2

Measured size-dependent deposition fractions of diesel exhaust particles (DEPs). Data are shown as group means of both types of DEPs for healthy subjects and COPD patients. For comparison, the deposition fractions are also shown for spherical hydrophobic oil particles for healthy subjects in a previous study (Löndahl et al. 2007). Bars indicate standard deviation between subjects.
