The Effect of Ventilation, Age, and Asthmatic Condition on Ultrafine Particle Deposition in Children

Figure 3

Measured and modeled deposition fraction curves by age for non-asthmatics. The curves suggest a strong effect of age on deposition. Age was used as a covariate in the ANCOVA analysis for total deposited fraction. Note reasonable agreement between our measurements and the ICRP model estimates.
