Abstract
The main aim of the present study was to estimate size segregated doses from e-cigarette aerosols as a function of the airway generation number in lung lobes. After a 2-second puff, 7.7Â ÃÂ 1010 particles (DTot) with a surface area of 3.6Â ÃÂ 103Â mm2 (STot), and 3.3Â ÃÂ 1010 particles with a surface area of 4.2Â ÃÂ 103Â mm2 were deposited in the respiratory system for the electronic and conventional cigarettes, respectively. Alveolar and tracheobronchial deposited doses were compared to the ones received by non-smoking individuals in Western countries, showing a similar order of magnitude. Total regional doses (DR), in head and lobar tracheobronchial and alveolar regions, ranged from 2.7Â ÃÂ 109 to 1.3Â ÃÂ 1010 particles and 1.1Â ÃÂ 109 to 5.3Â ÃÂ 1010 particles, for the electronic and conventional cigarettes, respectively. DR in the right-upper lung lobe was about twice that found in left-upper lobe and 20% greater in right-lower lobe than the left-lower lobe.
