Average exposures and doses during Plane Leaving (PL), Plane Arrival and fueling the plane (PA + FT combined), and over one flight cycle (t_PM4). From left to right: average event time (t) in minutes, average particle number concentration (n), mass concentration (m) and mass fraction smaller than 4 μm (m_PM4), inhaled number dose per minute (DR_N), predicted fraction of particles deposited in extra-thoracic (HA), tracheo-bronchial (TB) and alveolar (AL) lung regions, inhaled mass dose per minute (DRm), predicted fraction of mass deposited in extra-thoracic (HA), tracheo-bronchial (TB) and alveolar (AL) lung regions, total particles per event and total mass per event
