Fig. 10From: Quantitative biokinetics over a 28 day period of freshly generated, pristine, 20 nm titanium dioxide nanoparticle aerosols in healthy adult rats after a single two-hour inhalation exposureMechanisms and pathways of NP relocation, NP re-entrainment, and translocation across the ABB. Graphical sketch of mechanisms and pathways of NP relocation into the epithelium and the interstitium, subsequent re-entrainment back onto the alveolar epithelium and translocation across the ABB into blood circulation for distribution throughout the entire organismBack to article page
