摘要: Abstract Background: Respiratory tract deposition of air pollution particles is a key to their adverse health effects. This study was aimed determine the size-resolved fraction (DF) sooty wood smoke in lungs healthy subjects. The type investigated typical for household from solid fuels, which among largest environmental problems globally. Methods: Twelve volunteers inhaled diluted incomplete soot-rich combustion common stove. DF (10–500 nm) measured during three 15-min exposures each subject spontaneous breathing. Lung function using standard spirometry. Results: total DFs by particle number concentration were 0.34±0.08. can be compared with 0.21–0.23 subjects previous experiments pellet combustion. For mass, found this 0.22±0.06. and breathing frequency neg...
