[Deposition of air particles with polycyclic aromatic hydrocarbons (PAH) in human respiratory tract].
Atmospheric concentrations of five sizes of particles with PAH were determined in Taiyuan, and deposition of PAH in human respiratory tract was estimated. Results showed 47%-70% of air PAH concentrated in the particles less than 2 microns in diameter. Total PAH deposition in respiratory tract measured 12. 53 micrograms per day, and 53% of them deposited in nasopharyngeal region, 65% in tracheobronchial region and 32% in alveoli.
