Fig. 14From: 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 fractional concentrations (/g organ) after [105Ag]AgNP inhalation with those after [195Au]AuNP inhalation in secondary organs and tissues. Panels a and b show fractional concentrations of total translocation, carcass, and blood; panels c and d show fractional concentrations of liver, spleen, and kidneys; panels e and f show fractional concentrations of heart, brain, and uterus. Fractional concentrations are normalized to ILD. Mean (± SEM) for [105Ag]AgNP inhalation (n = 4) and n ≤ 6 for [195Au]AuNP inhalationBack to article page
