Abstract(s)
Indoor air pollution remains a great global concern. Particulate matter (PM), namely ultrafine particles
(aerodynamic diameter smaller than 0.1 μm; UFP), is considered as one of the most health-relevant air
pollutant for various subpopulations, one of which is children. Knowledge on the specific dose deposition
of PM may provide a critical link for better understanding of the relationship between individual exposure
and the respective health effects. Mathematical models have proven to be important tools for analysing
PM dose deposition in the respiratory tract providing relevant data for health risk assessment, source
apportionment of human lung burdens and control strategies purposes. This work aimed to estimate the
deposition dose of different PM sizes at different age categories. Inhalation dosimetry estimations were
carried out using the multiple-path particle dosimetry model (MPPD, v3.04). Age specific 5-lobe model
with uniform expansion was adopted in the present study
