ABSTRACT: The deposition of ultrafine particles, in
the human respiratory tract, from four highly impacted megacities across the
globe, was evaluated by using a pulmonary deposition model. It was found that,
for the locations studied, an average of 62% of atmospheric particles was retained
in the respiratory system. As expected, the model shows that smaller particles
penetrate deeper in the airways. In addition, it’s shown that children are more
susceptible than adults, retaining 8% more ultrafine particles.
