  • 摘要:Air fresheners are very popular and their aerosols contain components known to be toxic but we lack data on their penetration in the lungs which is dependent on their particle sizes. Thus we measured the particles sizes of various indoor deodorants and/or perfumes and derived an estimation of their regional deposition in the lungs. We used an Electronical Low Pressure Impactor which can separate aerodynamic diameters as low as 0.006 (6 nm) and as high as 10 µm. For all of our samples, 82 to 99% of the total number of particles have sizes of less than 0.3 µm and are thus susceptible to penetrate up to the smallest bronchi and alveoli: for a nose-breathing adult the probability of deposition in the airways of an aerosol with a MMAD of 0.2 µm is of 30% of the inhaled quantity, of which 15 % in alveoli and 3% in the bronchi according to the ICRP model. These results suggest a deposition in the deep lung and thus a potential for diffusion into the blood for most of the tested products.
