Fig. 13From: Quantitative biokinetics over a 28 day period of freshly generated, pristine, 20 nm silver nanoparticle aerosols in healthy adult rats after a single 1½-hour inhalation exposureComparison of retained [105Ag]Ag activity fractions in secondary organs and tissues after [105Ag]AgNP inhalation with those after [195Au]AuNP inhalation. Panels a and b show the activity fractions of total translocation, carcass, and blood; panels c and d show fractions for the liver, spleen, and kidneys; panels e and f show fractions for the heart, brain, and uterus. Fractions are normalized to ILD. Mean (± SEM) for [105Ag]AgNP inhalation (n = 4) and n ≤ 6 for [195Au]AuNP inhalationBack to article page
