Fig. 1 — Characterization of PbO NPs. A Particle number-size distribution of PbO NPs in the inhalation chambers measured by Scanning Mobility Particle Sizer (SMPS). B STEM image of PbO NPs. C Design of the inhalation experiment. Symbols of light circle indicate clean air, and symbols of dark circles indicate PbO NPs. D Surface area of PbO NP size distribution (dS/dlogD_p) calculated according to the ICRP deposition model. The surface area of fractions of PbO NPs deposited in the extrathoracic (S_ET), tracheobronchiolar (S_TB) and alveolar region (S_A) of lungs, S_T—the total surface area of generated PbO NPs, S_TB+A—the lung-deposited surface area. E Analysis of Pb concentration (ng/g) in organs following 11 weeks of PbO NP inhalation. Limit of detection in the lung, liver, kidney, and spleen was 75, 13, 84, and 117 ng/g Pb, respectively. The graphs values denote average ± SD; *p < 0.05; ***p < 0.001 by unpaired t-test
