OBJECTIVES ': 'This study determined the influence of exposure to environmental tobacco smoke (ETS) in aircraft on measured and perceived cabin air quality (CAQ), symptoms, tear-film stability, nasal patency, and biomarkers in nasal lavage fluid.'

'

METHODS ': 'Commercial aircrews underwent a standardized examination, including acoustic rhinometry, nasal lavage, and measurement of tear-film break-up time. Eosinophilic cationic protein, myeloperoxidase, lysozyme, and albumin were analyzed in the nasal lavage fluid. Inflight investigations [participation rate 98% (N=39)] were performed on board 4 flights, 2 in each direction between Scandinavia and Japan. Scandinavian crew on 6 flights from Scandinavia to Japan participated in postflight measurements after landing [participation rate 85% (N=41)]. Half the flights permitted smoking on board, and the other half, 0.5 months later, did not. Hygienic measurements showed low relative air humidity on board (2-10%) and a carbon dioxide concentration of %K acoustic rhinometry %K aerospace medicine %K environmental tobacco smoke %K eosinophil cationic protein %K lysozyme %K myeloperoxidase %K nasal congestion %K ocular symptom %K respirable particle %K tear-film break up time %R 10.5271/sjweh.576 %U https://www.sjweh.fi/show_abstract.php?abstract_id=576 %U https://doi.org/10.5271/sjweh.576 %P 514-522
