Abstract
The particle number concentration in ambient air is dominated by nanometer sized particles and most airborne particles carry a few charges. Our deposition studies in hollow airway casts demonstrate that electrical forces can result in significantly enhanced deposition of these particles in human airways. Deposition of highly charged airborne particles by electrical forces has been previously demonstrated experimentally in the respiratory tract in animals and people. Theory predicts that image forces will increase deposition of charged compared with neutral particles. However, modeling and experiments with particles whose deposition is dominated by inertial and gravitational forces suggest the effect is only discernible for highly charged particles. Our results show that the effect of single electrostatic charges carried by ultrafine particles cannot be neglected in modeling lung deposition.
